How To Make Node Server Always Load Within Service - node.js

I have a simple service file that is supposed to run a bash script that starts a node js server in my "build" directory.
Contents of the script are
#!/bin/bash
cd /home/path/to/build && npm install -g serve && serve -l 5679
However, I get the error => /usr/bin/env: ‘node’: No such file or directory
Even when I try a symlink like so
#!/bin/bash
cd /home/path/to/build && ln -s /usr/bin/nodejs /usr/bin/node && npm install -g serve && serve -l 5679
I get the error => failed to create symbolic link ‘/usr/bin/node’: File exists
Please how do I fix this? I wouldn't want my user to have to manually start serving on each reboot. It also works if I add the script contents straight to terminal.
Thanks for any help!

Turns out I had to install node with a different method (inspired by https://www.geeksforgeeks.org/installation-of-node-js-on-linux/) to ensure it actually existed in /usr/bin because ExecStart didn't like having the "serve" command working with my symlink node.
Step 1: Open your terminal or press Ctrl + Alt + T and use the following commands to update and upgrade the package manager:
sudo apt-get update
sudo apt-get upgrade
Step 2: Install Python software libraries using the following command:
sudo apt-get install software-properties-common
Step 3: Add Node.js PPA to the system.
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
Note: Here, we are installing node.js version 14, if you want to install version 11, you can replace setup_14.x with setup_11.x.
Step 4: To Install Node.js and NPM to your Ubuntu machine, use the command given below:
sudo apt-get install nodejs
Step 5: Once installed, verify it by checking the installed version using the following command:
node -v or node –version
npm -v or npm –version

Installed Node.js but File Cannot be Found by Command Prompt

I installed node.js onto my Raspberry Pi, which is running on Raspbian Stretch.
To install, I used the command $ sudo apt-get install -y nodejs. There were no problems with installation.
When I try to test the installation by typing $ nodejs -v into the command prompt, it returns
nodejs: command not found
If I try to install it again, the prompt returns
nodejs is already the newest version (8.11.1~dfsg-2~bpo9+1)
Also, when I look into my /usr/bin folder, I see that node.js is there.
I've spent a while searching for what could be causing this issue to no avail. I think maybe the node.js file is in the wrong folder, but none of the tutorials I've read has a step where you would move the file.
Any help to get node.js to work would be greatly appreciated! :)
Try this:
Step 1: This command updates our Debian apt package repository to include the NodeSource packages.
$ curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
Step 2: Install NodeJS (THis will ensure you are installing latest version)
sudo apt install -y nodejs
Step 3: Enjoy NODEJS in RaspberryPi
$ node -v
v10.6.0
$ node
> 1 + 3
4
> # We can hit Ctrl-C twice to exit the REPL and get back to the bash (shell) prompt.
If you are having conflicts with previous NODE installations, do this to remove all existing installations:
Running which node will return something like /path/bin/node
Then run cd /path
Then run rm -r bin/node bin/node-waf include/node lib/node lib/pkgconfig/nodejs.pc share/man/man1/node.1
Hope it helps!

Where is node_modules directory?

If I create a new AWS instance (ubuntu 16.04 LTS) and create a directory (NodeT) then run the 2 commands:
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
( from https://nodejs.org/en/download/package-manager/ )
I then have successfully installed node and npm?
node -v
npm -v
return their versions.
So have I created it locally on NodeT or globally on the whole system?
Where is the node_modules directory?
I am trying to install mongodb on the system and am having troubles. I believe I need to run:
nodejs node_modules/node-sass/scripts/install.js
npm rebuild node-sass
( from https://github.com/sass/node-sass/issues/1579 )
to solve my problems, but the command can't find the node_modules directory and either can I.
I'm clearly missing the basic concept of nodejs. Any help would be appreciated.
type this command in your terminal
sudo npm root -g
Output (example):
/usr/local/lib/node_modules

Rookie error with Node.js, Johnny Five and Raspbian

I'm currently trying to communicate with Arduino through a web server created with Node.js installed on my Orange PI PC. In order to do this, I tried to use the module called johnny five, but the only output I receive is a bunch of errors.
I'm using Raspbian v0.8.0 for Orange PI PC.
I installed node v0.10.0 by using wget plus the link.
Then, I unpacked the file by using:
cd /usr/local
sudo tar xzvf ~/node-v0.10.0-linux-arm-pi.tar.gz --strip=1
The version of node is 0.10.0 and the NPM's version is 1.2.14. When I tried to update the npm with the command npm install npm -g
these errors came in
Then, I tried to install johnny-five by following the guide that I've found on the johnny-five website which is linked to Github
And this happened
If I try to run a program, many error appear saying at the top of them 'cannot find module johnny five'.
This version of node is the only one that works for me after checking many other of them.
Try and set up a more advanced version of node.js. I had success with node v4. This will update NPM/Node.
# install updates
sudo apt-get update && sudo apt-get upgrade
# install node
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs
# test
node -v
npm -v
# clone the code of the project in a folder and continue normally
You can find an old version in the Heroku web:
https://node-arm.herokuapp.com/
But if you want a more recent go to https://nodejs.org/en/download/ and dowload a new one from Linux Binaries (ARM). Unzip the binary archive to any directory you wanna install Node, I use /usr/lib/nodejs:
sudo mkdir /usr/lib/nodejs
sudo tar -xJvf node-v8.9.4-linux-armv7l.tar.xz -C /usr/lib/nodejs
sudo mv /usr/lib/nodejs/node-v8.9.4-linux-armv7l /usr/lib/nodejs/node-v8.9.4
Set the environment variable ~/.profile, adding below to the end:
# Nodejs
export NODEJS_HOME=/usr/lib/nodejs/node-v8.9.4
export PATH=$NODEJS_HOME/bin:$PATH
Refresh profile:
.~/.profile
Test installation using:
node -v
and
npm version

Gulp global installation not possible [duplicate]

NodeJS interpreter name(node) on Ubuntu has been renamed to nodejs because of a name conflict with another package. Here's what the readme. Debian says:
The upstream name for the Node.js interpreter command is "node".
In Debian the interpreter command has been changed to "nodejs".
This was done to prevent a namespace collision: other commands use
the same name in their upstream, such as ax25-node from the "node"
package.
Scripts calling Node.js as a shell command must be changed to instead
use the "nodejs" command.
However, using nodejs mucks up installing packages using npm. Package installation fails with the following error:
sh: 1: node: not found
npm WARN This failure might be due to the use of legacy binary "node"
npm WARN For further explanations, please read /usr/share/doc/nodejs/README.Debian
How do I make npm understand that nodejs is already installed on the system but the interpreter name is different?
TL;DR:
sudo apt-get install nodejs-legacy
First of all let me clarify the situation a bit. In summer 2012 Debian maintainers decided to rename Node.js executable to prevent some kind of namespace collision with another package. It was very hard decision for Debian Technical Committee, because it breaks backward compatibility.
The following is a quote from Committee resolution draft, published in Debian mailing list:
The nodejs package shall be changed to provide /usr/bin/nodejs, not /usr/bin/node. The package should declare a Breaks: relationship with
any packages in Debian that reference /usr/bin/node.
The nodejs source package shall also provide a nodejs-legacy binary package at Priority: extra that contains /usr/bin/node as a symlink to
/usr/bin/nodejs. No package in the archive may depend on or recommend
the nodejs-legacy package, which is provided solely for upstream
compatibility. This package declares shall also declare a Conflicts:
relationship with the node package.
<...>
Paragraph 2 is the actual solution for OP's issue. OP should try to install this package instead of doing symlink by hand. Here is a link to this package in Debian package index website.
It can be installed using sudo apt-get install nodejs-legacy.
I have not found any information about adopting the whole thing by NPM developers, but I think npm package will be fixed on some point and nodejs-legacy become really legacy.
Try linking node to nodejs. First find out where nodejs is
whereis nodejs
Then soft link node to nodejs
ln -s [the path of nodejs] /usr/bin/node
I am assuming /usr/bin is in your execution path. Then you can test by typing node or npm into your command line, and everything should work now.
You can also install Nodejs using NVM or Nodejs Version Manager There are a lot of benefits to using a version manager. One of them being you don't have to worry about this issue.
Instructions:
sudo apt-get update
sudo apt-get install build-essential libssl-dev
Once the prerequisite packages are installed, you can pull down the nvm installation script from the project's GitHub page. The version number may be different, but in general, you can download and install it with the following syntax:
curl https://raw.githubusercontent.com/creationix/nvm/v0.16.1/install.sh | sh
This will download the script and run it. It will install the software into a subdirectory of your home directory at ~/.nvm. It will also add the necessary lines to your ~/.profile file to use the file.
To gain access to the nvm functionality, you'll need to log out and log back in again, or you can source the ~/.profile file so that your current session knows about the changes:
source ~/.profile
Now that you have nvm installed, you can install isolated Node.js versions.
To find out the versions of Node.js that are available for installation, you can type:
nvm ls-remote
. . .
v0.11.10
v0.11.11
v0.11.12
v0.11.13
v0.11.14
As you can see, the newest version at the time of this writing is v0.11.14. You can install that by typing:
nvm install 0.11.14
Usually, nvm will switch to use the most recently installed version. You can explicitly tell nvm to use the version we just downloaded by typing:
nvm use 0.11.14
When you install Node.js using nvm, the executable is called node. You can see the version currently being used by the shell by typing:
node -v
The comeplete tutorial can be found here
Install nvm first using:
curl https://raw.githubusercontent.com/creationix/nvm/v0.11.1/install.sh | bash
Run command
source ~/.profile
Now run this and this will show will all installed or other versions of packages:
nvm ls-remote
Installed packages will be in green. Install whatever version you want:
nvm install 6.0.0
Check where is not installed:
which node
Check current version:
node -v
n=$(which node);
n=${n%/bin/node};
chmod -R 755 $n/bin/*;
sudo cp -r $n/{bin,lib,share} /usr/local
sudo apt-get --purge remove node
sudo apt-get --purge remove nodejs-legacy
sudo apt-get --purge remove nodejs
sudo apt-get install nodejs-legacy
source ~/.profile
Combined the accepted answer with source ~/.profile from the comment that has been folded and some clean up commands before. Most likely you will also need to sudo apt-get install npm after.
for me problem was solved by,
sudo apt-get remove node
sudo apt-get remove nodejs
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo ln -s /usr/bin/nodejs /usr/bin/node
alias node=nodejs
rm -r /usr/local/lib/python2.7/dist-packages/localstack/node_modules
npm install -g npm#latest || sudo npm install -g npm#latest
Here's another approach I use since I like n for easy switching between node versions.
On a new Ubuntu system, first install the 'system' node:
curl -sL https://deb.nodesource.com/setup | sudo bash -
Then install n module globally:
npm install -g n
Since the system node was installed first (above), the alternatives system can be used to cleanly point to the node provided by n. First make sure the alternatives system has nothing for node:
update-alternatives --remove-all node
Then add the node provided by n:
update-alternatives --install /usr/bin/node node /usr/local/bin/node 1
Next add node provided by the system (the one that was installed with curl):
update-alternatives --install /usr/bin/node node /usr/bin/nodejs 2
Now select the node provided by n using the interactive menu (select /usr/local/bin/node from the menu presented by the following command):
update-alternatives --config node
Finally, since /usr/local/bin usually has a higher precedence in PATH than /usr/bin, the following alias must be created (enter in your .bashrc or .zshrc) if the alternatives system node is to be effective; otherwise the node installed with n in /usr/local/bin takes always precedence:
alias node='/usr/bin/node'
Now you can easily switch between node versions with n <desired node version number>.
On Linux Mint 17, I tried both solutions (creating a symlink or using the nodejs-legacy package) without success.
The only thing that finally worked for me was using the ppa from Chris Lea:
sudo apt-get purge node-*
sudo apt-get autoremove
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs
This installed node version 10.37 and npm 1.4.28. After that, I could install packages globally.
As other folks already mention, I will suggest not to use "sudo apt-get" to install node or any development library. You can download required version from https://nodejs.org/dist/v6.9.2/ and setup you own environment.
I will recommend tools like nvm and n, to manage you node version. It is very convenient to switch and work with these modules.
https://github.com/creationix/nvm
https://github.com/tj/n
Or write basic bash to download zip/tar, extract move folder and create a soft link. Whenever you need to update, just point the old soft link to new downloaded version.
Like I have created for my own, you can refer:
https://github.com/deepakshrma/NodeJs-4.0-Reference-Guide/blob/master/nodejs-installer.sh
#Go to home
cd ~
#run command
#New Script
wget https://raw.githubusercontent.com/deepakshrma/NodeJs-4.0-Reference-Guide/master/nodejs-installer.sh
bash nodejs-installer.sh -v lts
#here -v or --version can be sepecific to 0.10.37 or it could be latest/lts
#Examples
bash nodejs-installer.sh -v lts
bash nodejs-installer.sh -v latest
bash nodejs-installer.sh -v 4.4.2
Simple solution from here
curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash --
sudo apt-get install nodejs
You can specify version by changing setup_x.x value, for example to setup_5.x
Your System is not able to detect the path node js binary.
1.which node
2.Then soft link node to nodejs
ln -s [the path of nodejs] /usr/bin/node
I am assuming /usr/bin is in your execution path. Then you can test by typing node or npm into your command line, and everything should work now.
Uninstall whatever node version you have
sudo apt-get --purge remove node
sudo apt-get --purge remove nodejs-legacy
sudo apt-get --purge remove nodejs
install nvm (Node Version Manager) https://github.com/creationix/nvm
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh | bash
Now you can install whatever version of node you want and switch between the versions.
I fixed it unlinking /usr/sbin/node (which is linked to ax25-node package), then I have create a link to nodejs using this on command line
sudo ln -s /usr/bin/nodejs /usr/bin/node
Because package such as karma doesn't work with nodejs name, however changing the first line of karma script from node to nodejs, but I prefer resolve this issue once and for all
For me the fix was removing the node* packages and also the npm packages.
Then a fresh install as:
sudo apt-get install autoclean
sudo apt-get install nodejs-legacy
npm install
Problem is not in installer
replace nodejs with node or change the path from /usr/bin/nodejs to /usr/bin/node
This is the your node is not properly install, first you need to uninstall the node then install again.
To install the node this may help you
http://array151.com/blog/nodejs-tutorial-and-set-up/
after that you can install the packages easily. To install the packages this may help you
http://array151.com/blog/npm-node-package-manager/
you can create a link ln -s nodejs node in /usr/bin
hope this solves your problem.
node -v // first check it's install or not
npm -v
sudo apt install npm
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash –
sudo apt-get install nodejs
then check
node -v or node –version
npm -v or npm –version
or you can remove package.lock json file / node_modules than run npm i
I hope it'll work fine
steps : https://www.geeksforgeeks.org/installation-of-node-js-on-linux/
Faced same issue, steps below worked for me.
Install curl on your system then run NVM installer script.
sudo apt install curl
curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
Load the environment
source ~/.profile
Install the supported version of Node.js.
nvm install 16.15.1
Confirm the installation
node -v

Installing NPM on AWS EC2

Working on Ec2 on AWS.
I have installed Node.js and it works fine.
But the problem arises when trying to install npm.
I am using the following command to install it:
sudo curl http://npmjs.org/install.sh | sh
But the install seems to freeze...
I get "fetching: http://registry.npmjs.org/npm/-/npm-1.0.106.tgz" at the prompt and it stays on like this.
Have any idea what is going on here?
sudo yum install nodejs npm --enablerepo=epel
Follow this AWS Tutorial that uses Node Version Manager.
Node Version Manager (NVM) lets you install multiple versions of Node.js and switch between them.
Here are the steps:
Install NVM
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.0/install.sh | bash
Activate NVM
. ~/.nvm/nvm.sh
Install Node (choose version)
nvm install 15.0.0
Confirm Successful Installation
node -e "console.log('Running Node.js ' + process.version)"
To install NodeJS 6.x execute the following commands:
curl -sL https://rpm.nodesource.com/setup_6.x | sudo -E bash -
yum install nodejs --enablerepo=nodesource
Update
You can install NodeJS 7 and 8 in the same way. Just specify the version you need instead of 6 in the command above.
Update
To update to NodeJS 16 (or any other version) do the following:
rm -rf /etc/yum.repos.d/nodesource-el*
curl -sL https://rpm.nodesource.com/setup_16.x | sudo -E bash -
yum install nodejs --enablerepo=nodesource
Simplest way to install npm/nodejs on Amazon Linux 2 ec2 isntance:
First install epel repo using amazon-linux-extras command as below:
sudo amazon-linux-extras install epel
Now install npm and nodejs as below:
sudo yum install nodejs npm
you can verify the version of node and npm as below:
node -v
npm -v
PS. I've tested this on Amazon Linux 2 AMI (HVM) ec2 instance.
This guide worked perfectly: https://tecadmin.net/install-latest-nodejs-amazon-linux/
Make sure you have make
# sudo yum install -y gcc-c++ make
Install source
# curl -sL https://rpm.nodesource.com/setup_14.x | sudo -E bash -
Install node
# sudo yum install -y nodejs
Note - you'll have to run sudo npm install to get the installs to work.
Firstly
sudo yum install make
You can run this to get zip of desired version of node
wget https://nodejs.org/dist/v8.10.0/node-v8.10.0.tar.gz
Then you can unzip it like this
tar -xvf node-v8.10.0.tar.gz
then go in to the extracted directory and install node like this
./configure && make && sudo make install
I found his tutorial that has been very usefull to me: The last chapter explains how to install node and npm compiling it.
http://iconof.com/blog/how-to-install-setup-node-js-on-amazon-aws-ec2-complete-guide/#installNode
Get the http://npmjs.org/install.sh file on your system first and then execute it directly instead of piping with curl.
Use chmod +x install.sh to make it executable
Then run ./install.sh
I did it manually. Why mess with installers that break or don't put things where I want them? Such were the problems encountered while installing *node.js" on Amazon Web Services, that a manual install was the easy way to get the result I wanted.
I want a GLOBAL install of node and npm on AWS. By that I mean install should be put in a place like /usr/bin, so that all users have access. Surprisingly, AWS apparently doesn't give support to that idea. AWS encourages using nvm, node version manager, but that seems to always install in a user directory, and not a system level directory. After being frustrated when the "rpm" solutions (mentioned elsewhere) failed, I finally decided to just do the installation manually.
In a browser, go to nodejs.org download page:
https://nodejs.org/en/download/
Find a link that says:
All download options
Click through that; it goes to an index page with a URL like:
https://nodejs.org/dist/v14.16.1/
There I looked for the name that had "linux" and "x86" in the name.
I wrote this down, or select-and-copied, to get the correct spelling.
In my case it was:
node-v14.16.1-linux-x64.tar.gz
Putting the two parts together, I got the following URL:
https://nodejs.org/dist/v14.16.1/node-v14.16.1-linux-x64.tar.gz
So that's what is to be downloaded using curl.
I have a "temp" directory conveniently located in my home dir.
cd ~/temp
The download was accomplished with "curl". Note that the -o option was used to give the output file the name of my choosing. Of course, I chose to give it the same name as the web site file.
curl -o node-v14.16.1-linux-x64.tar.gz https://nodejs.org/dist/v14.16.1/node-v14.16.1-linux-x64.tar.gz
Untar the downloaded file.
tar xf node-v14.16.1-linux-x64.tar.gz
Conveniently, it creates its own directory. Go there.
cd node-v14.16.1-linux-x64 || exit 1;
Observe that the delivery consists of a relatively small number of files and directories (since node_modules is dealt with as a unit).
In my case, I had an old and bad implementation still installed, so the following commands were used to move aside any junk that might happen to be in the way. Some commands errored out because the old junk didn't exist. That's ok, error while moving to -OLD just means there is nothing to move; which is good.
Note: I put all these mv (move) commands into a script file, made it executable, and ran it as sudo. The alternative is to run each line individually as sudo.
mv /usr/bin/node /usr/bin/node-OLD
mv /usr/bin/npm /usr/bin/npm-OLD
mv /usr/bin/npx /usr/bin/npx-OLD
mv /usr/include/node /usr/include/node-OLD
mv /usr/lib/node_modules /usr/lib/node_modules-OLD
mv /usr/share/doc/node /usr/share/doc/node-OLD
mv /usr/share/man/man1/node.1 /usr/share/man/man1/node.1-OLD
mv /usr/share/systemtap/tapset/node.stp /usr/share/systemtap/tapset/node.stp-OLD
An here is the actual install. Remember, this is occurring in the untarred directory, in my case node-v14.16.1-linux-x64.
mv bin/node /usr/bin
mv bin/npm /usr/bin
mv bin/npx /usr/bin
mv include/node /usr/include
mv lib/node_modules /usr/lib
mv share/doc/node /usr/share/doc
mv share/man/man1/node.1 /usr/share/man/man1
mv share/systemtap/tapset/node.stp /usr/share/systemtap/tapset/
That's it, all finished.
Latest version 18 has dependency I think..
node: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by node)
Finally I got solution by running by running following commands.
sudo apt-get remove nodejs
nvm install 16.15.1
v16.15.1 node version and npm v v16.15.1 is installed.
For same make sure nvm is installed in your machine.
This works for me:
sudo apt install npm
Edit as my answer wasn't pertinent anymore:
Try:
curl --silent --location https://rpm.nodesource.com/setup | bash -
yum -y install nodejs
