Problem installing socket.io on Fedora Core - node.js

I'm trying to install socket.io on my machine, but I keep encountering errors when I run npm install socket.io as directed on their website. I'm not sure if I have version incompatibilities for npm or node.js or if I'm simply missing something obvious. As far as I can tell, I have the most recent stable version of both of them.
When I run the install command, the console outputs 40+ errors, and at the end I am given the line npm not ok. Any ideas as to what is going wrong?

What is the error?
Are you installing npm using code from git? I can only guess that you are not using a stable code, because the master branch from git is often unstable.
If that is the case, what you can do is to get the latest code from the git repository and install it again.
$ cd npm
$ git pull
$ make install
Hope it will solved your problem.

You need to provide an error log if you want anyone to try and troubleshoot your problem. It would also be helpful to know whether you installed Node and NPM from source or RPM. Furthermore, if you installed from source, did you do a standard install or did you make customisations?
If you are able to start from scratch, I suggest following the steps below and seeing how you go. Installing into your home directory won't require root and it makes it easier to clear everything out if you need to start again.
Install the stable release of Node in your home directory (use ./configure --prefix=~/Node/)
Set your path as appropriate (ie. PATH=/home/user/Node/bin:$PATH)
Run the standard NPM installer (curl http://npmjs.org/install.sh | sh)

LESS instalation - node file does not exist on Linux

I'm trying to install LESS css in Netbeans, but I'm running into one problem after another. As such, I already have LESS installed, but I can't get it running.
Less is installed via the npm package, I installed it using the packaging system, less itself via Terminal. The first problem I had was that despite a successful installation, Netbeans didn't get to the files he needed (usr/local/), I could either change permissions there, which I don't want to dig into, or change the location. So I changed the location of the .npm and .npm-global folders to my root (home/ivet/), from where Netbeans managed to load it.
So I set everything there, the general settings and the specific project and it looked fine.
I want it to be converted to css automatically after saving, but it throws the message "/usr/bin/env:"node": Directory or file does not exist" and the target css file is still empty.
I found a few advices, basically the same: "ln -s /usr/bin/node/ usr/local/bin/nodejs", but it tells me that the link already exists and nothing will solve it. On closer inspection, I found that the link does exist, but the target file does not exist.
I've also found that installing Nodejs legacy solves this, but this is an older piece of advice, the package no longer exists, and terminal pretends to have the packages that replace this installed. Even when searching for via grep, I couldn't find the file it should link to (neither node nor nodejs).
There are the same tips everywhere that don't work for me and I don't know what to try next. I use Linux Mint 20, but I call myself a Linux BFU, so please write answer step by step :-D
Thanks for the advice
Try completely removing NodeJS & npm and try to install NodeJS using nvm i.e., node version manager.
You can follow this link on how to install nodejs and npm using nvm.
It's always a tedious task sometimes when it comes to package managment with npm, so it's better to go with nvm and I strongly suggest to always have a fallback option for node version when using with or without nvm i.e.,
NodeJS LTS version & NodeJS latest/stable version.
There's also an alternative solution i.e.,you can try switching to yarn package manager.
I've had this issue on Ubuntu and I've resolved it likes this:
First of all I've removed node and npm packages via
sudo aptitude remove node npm
Then I've added the official repositories
curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash -
After which I've just updated the list of packages with sudo aptitude update and then installed Node
sudo aptitude install nodejs npm
And that was it. With these steps done, everything just started to work.

npm hangs on postinstall / unlock

I have a Linux server that runs some virtual Machines using KVM. Host machine is a Debian derivate with kernel 2.6.32-32(-pve).
In roughly 75% of the times I run npm install, it hangs while installing modules. I ran it in silly debug level and it always hangs at the line
npm info postinstall [module name] (older npm versions)
or
npm verb unlock done using [...] (newer npm versions)
forever.
It happens in every project on the host machine and on the virtualized systems for every node and every npm version I have tested (a lot, including the newest ones (2.7.x atm)).
It also is not deterministic. Sometimes it works, sometimes not and most of the times it hangs on a different module.
On my dev machine (which is in the same network, running OS X 10.10) it works fine.
I am not behind any kind of proxy.
What could possibly be wrong here?
EDIT: For the time being I solved this problem by checking in all my dependencies as gzipped files using https://github.com/JamieMason/shrinkpack
I was having the same issue for several hours, and couldn't work out what the problem was. I tried re-installing everything a few times, manually installing individual modules, switching from x64 to x86 versions of NodeJS, etc, and got nowhere.
In the end, I changed networks, from WiFi over ADSL2+ [~2mbps] to 4G Hotspot [~20mbps] and it worked in 30 seconds. No idea why, since it didn't seem like a network speed issue, but it solved the problem.
Hope this helps someone else, too!
I had the same problem on our Jenkins slaves based on Ubuntu, and it was solved by upgrading npm.
Default npm installed by apt-get has version 1.3.10 now, which is very old (shown by npm --version). There are at least two ways to upgrade it:
Run sudo npm install -g npm command. If you want to install a specific version you can run append it at the end of command: sudo npm install -g npm#2.1.3.
Or you could add NodeSource repositories using these instructions and run usual sudo apt-get update.
I have the same problem on Windows. I deleted my npm-cache folder and reinstalled npm. Everything started working normally after that.
The npm-cache folder can be found at
<your-drive>\Users\<your-name>\AppData\Roaming\npm-cache
Remember to turn on 'View hidden files because the AppData folder by default is hidden
You can reinstall npm by using the command,
npm i npm -g
On Windows make sure you are in a native CMD (not in VSCODE or whatever IDE). Also, try increasing the max memory limit for node:
set NODE_OPTIONS=--max_old_space_size=8096
I did the same, switched my network from WiFi to 3G and it worked.
I'm experiencing the same problem, this is the issue on Github:
https://github.com/npm/npm/issues/7862
There are some useful tips that seemed to help a few people.
For me doing $ npm install -g node-gyp (as suggested here: http://gangmax.me/blog/2013/05/13/resolve-npm-update-node-gyp-hung-problem/) fixed the problem.
I had the same problem and just run
npm cache clean
And it works!
Had this same problem in Windows. The solution was to restart after installing node and npm and then run command prompt as administrator.
In my case, a system restart did the work.
I ran npm install --verbose which suggested some lock on a file in npm-cache. And I think the system released the file (which was under use) after the system restart. I am using windows.
Try cloning the project again and then run npm install to install the packages in your terminal.
I ran into this with npm v6, and it turned out I was just being impatient. I just needed to wait a little longer and it proceeded to the next step.
npm cache clean --force
works for me :)
=> this method working with me When npm block in installation Package for IONIC installation and ReactNative and another package npm.
you can change temporary :
npm config set prefix C:\Users[username]\AppData\Roaming\npm\node_modules2
change the Path in Environment Variables set C:\Users[username]\AppData\Roaming\npm\node_modules2
Run the your command to install your package .
open file explorer copy the link C:\Users[username]\AppData\Roaming\npm\node_modules
ok file yourpackage.CMD created another folder Created "node_modules2" in node_modules and contain your package folder.
copy your package file CMD to parent folder "npm"
copy your package folder to parent folder "node_modules"
now run npm config set prefix C:\Users[username]\AppData\Roaming\npm
change the Path in Environment Variables set C:\Users[username]\AppData\Roaming\npm
now package working correctly with Command line

Why does Yeoman require connecting to the internet when starting a new project?

Recently, I started using Yeoman to create static site projects built with Jekyll. yo jekyllrb runs fine but, in terms of security, I'm concerned about the part that comes after it prints:
I'm all done. Running bower install & npm install for you to install the required dependencies. If this fails, try running the command yourself.
If I'm not connected to the internet bower install still runs fine, but npm install gives the following error:
npm ERR! git fetch -a origin (git://github.com/gruntjs/grunt-contrib-watch.git) fatal: unable to connect to github.com:
npm ERR! git fetch -a origin (git://github.com/gruntjs/grunt-contrib-watch.git) github.com: Name or service not known
npm ERR! git fetch -a origin (git://github.com/dannygarcia/grunt-jekyll.git) fatal: unable to connect to github.com:

From what I understood by reading what is said in response to this question about sudo, npm, and chroot, running an npm install potentially executes code from the internet and is therefore recommended to prefix such command with sudo in order to allow npm to downgrade privileges. Doing an npm config set unsafe-perm=false is supposed to force one to follow this recommendation. This, however does not have any effect on npm install, I guess, because it's a local install. This makes sense to me since (especially in a dev. env.) the code that is installed locally is most likely supposed to be executed by one's own user. What does not make sense to me is that, in the case of Yeoman, code has to be fetched from the web and executed with the same frequency that I start a new (simple) project, especially since npm does not check signatures. I imagine that a solution to this would be to disable npm for my user and copy the double-checked node_modules dir from another similar project. In the case of projects with more diverse needs, I would consider using a sandbox (perhaps with chroot).
What is the standard way of dealing with this issue? Does Yeoman provide any options that would allow one to work around this problem?
I think Bower is a little smarter about handling packages than npm, most times it will use a cached copy of a plugin so if you have jQuery version X installed in one project, and then use that same version in another, then Bower doesn't need to connect to the Internet in order to resolve that dependency, it will just pull from cache instead. That being said you still would have had to download that package in the first place in order to have that cached copy.
On the sudo thing, I've since learned that you shouldn't use sudo with package managers. Just going to quote from this answer here: "sudo npm install -g grunt-cli" gives me an error
According to the maintainer of npm, installing packages with sudo is
considered bad practice because you are allowing that package to have
complete control of your system and you can't and SHOULDN'T trust
these packages with root access. Think Debian's long release cycles as
an extreme example of protecting end users from community maintained
packages for this exact reason.
http://howtonode.org/introduction-to-npm
You should do what Issaacs suggests and chown your /usr/local folder
so you have RW permissions.
So the issue you're having is that you don't want to run things with sudo. So don't. But if npm install throws an error it may be that you need to chown -R /usr/local, or another issue. In the case of node modules, they are installed per project, unless you install them globally with the -g flag, and even then you can have multiple projects with different versions of packages.
If you already have a project that uses Y version of grunt, yeoman etc, you might just want to copy over the relevant modules from another project. This will still work. However it's a lot simpler to do npm install <package, ...> --save or --save-dev to persist these dependencies in your package.json file, which makes cloning the project to another machine a lot easier (git clone <project> && npm i)
TLDR: Both Bower and npm install packages from the Internet, whether run under Yeoman or not; Bower is different in that sometimes it can make use of a cache.

NPM appears to do nothing on Linux Mint 15

searched, and did not see this specific problem.
Trying to get a MEAN stack built on my Linux Mint machine, and bumping into a bit of an unusual issue.
Got MongoDB installed, and finally got it running correctly (none of the instructions ANYWHERE mentioned having to create the /data/db/ directory and set permissions, go figure).... it works now.
Got NodeJS installed, and it appears to work correctly.
I had been told (apparently incorrectly) that NPM installs right alongside Node, with:
sudo apt-get install nodejs
but:
$ npm
bash: /usr/bin/npm: No such file or directory
So I go ahead and install NPM separately.
$ sudo apt-get install npm
Seems to work, so far, no errors, and it looks like it is pulling down the NPM package and installing it...
$ nodejs -v
v0.10.21
$ npm -v
$
?? It simply fails to respond without any error... so I try:
$ npm install grunt -g --save-dev
$
Same completely silent failure... in fact, NOTHING I could do gets a response out of NPM.
Looked all over the web, and saw nothing similar anywhere... found out that NPM holds its cache files in ~/.npm and noticed that this folder didn't exist (kinda like the mongo issue above), so I created it, and set permissions to 7777... still nothing.
Purged and re-installed both node and npm, tried installing them both together and separately (yes, desperation)... still no love.
WTF am I doing wrong?
I would love, eventually, to have a nice development environment setup, hopefully with Cloud9 as a local IDE.... but already pulling my hair out.
=========================================================================================
OK, after a few more headaches, this is up and built now... thank you all.
Would love to mark both as answers, but it won't let me.
npm does come with node. Where is apt-get pulling it from? I install the Mac OS X packages on my Mac for development and npm does in fact come with it. I compile from source on my CentOS server and npm comes with it.
Your package provider may be providing them separately as a (in)convenience to you.
As for why your npm command does not work after installation, I can't say for sure, but I am suspicious of your use of --save-dev and -g together.
-g means to install globally, which means 2 things:
It will be installed outside of your npm package's structure into a system location like /usr/bin or /usr/local/bin
It requires root access to install. Did you use sudo to run it with root access?
Both of those requirements conflict with --save-dev which records the package as a dependency in your package.json file so that future npm install commands will install that package within the project space.
That said, I happen to know a lot about grunt. It has 2 parts, a globally installed tool and the package-specific tool. The correct way to install it is:
$ [sudo] npm install -g grunt-cli
$ npm install grunt --save-dev
This will install the grunt-cli package into a system location guaranteed to be in the $PATH, which turns around and looks for a package-specific grunt installed which is not system-wide.
When installing nodejs with npm, this one-liner worked for me.
sudo apt-get install nodejs nodejs-dev npm
I don't believe npm comes with the nodejs installation in the apt repo. Try to install npm separately using the following tutorial http://www.giantflyingsaucer.com/blog/?p=1688 'To install NPM ....'
====== Edit ====
node and npm IS separate. Follow the official wiki and everything should be fine

npm comes with node now. What does this mean?

Node noob here.
I had previously installed both npm and node separately.
Apparently, npm comes with node now. (link)
To my newbie mind, this means my previous dual installation is old and ugly. 1 binary > 2 binaries. So i uninstalled both.
Then I installed the latest node following the procedure. (i am running eOS)
Terminal
user#box:-$ which node
/usr/bin/node
user#box:-$ node -v
v0.10.22
user#box:-$ which npm
user#box:-$ npm -v
bash: /usr/bin/npm: No such file or directory
I can always run:
curl https://npmjs.org/install.sh | sh
but that seems to indicate that npm is actually NOT included in node.
When they say they are included do they just mean the code is in the same repo, but the binaries are still different?
Final question I have /usr/bin/node as well as /usr/bin/nodejs
can i delete one of these? im not sure when/where i picked up a second copy.
Yes, the nodejs package includes both node and npm executables. The code for each has its own repo, but when packaged both are included.
npm source: https://github.com/isaacs/npm
node source: https://github.com/joyent/node
When you install that .deb file from the PPA, you should get both /usr/bin/nodejs and /usr/bin/npm and 2 symlinks at /usr/bin/node (which points to) /etc/alternatives/node (which points to /usr/bin/nodejs).
If any of this isn't true, your install didn't fully succeed, most likely due to conflicting files you left around from your manual install. I would suggest uninstalling the .deb then making sure there are no stale files left from your manual install and then installing again.
Only node.js packages comes with npm. so if you are installing using an .msi, .exe, .dmg .pkg, .deb or using a package installer like apt-get, yum or brew, then you'll have both node and npm.
However,npm is not part of the node core. if you are installing node and using a method where you are using ./configure or make install || make link, then npm will not be installed, and will need to be compiled using the same type of installation, and node will have to be placed on your path.
If you used git, or unzipped node and you can see a configure script, then you will also need to acquire npm.
I've had issues (mostly on Mac) with npm ending up in directories that aren't in the terminal PATH. If you can figure out where npm is located, you can just add it to your path with something like:
export PATH=$PATH:/path/to/npm
I think (I'm not on a mac so I can't check at the moment) that it sometimes gets put in /usr/local/share/. But at any rate, the problem is likely NOT that npm isn't installed, but that it's installed somewhere you're not expecting.
Few months ago i had started learning the react so all this stuff i needed to install my laptop that had the ubuntu operating system.
What i did -- First i installed the node and without knowing that it came up with the npm package. I installed the npm package again.. but there was no conflict at all.
But after exploring all these things that nodejs have npm package. So i uninstalled the npm package due to concern about memory usage..
And Now everything is working fine....
