I have installed Strongloop using npm install -g strongloop on my Ubuntu 14.04 server. The slc command does not work. It says
The program 'slc' is currently not installed. You can install it by typing:
sudo apt-get install heimdal-multidev
How can I get it to run the Strongloop CLI instead of looking for this package? I have added this to my PATH and it still doesn't work. Any ideas?
Other Strongloop commands, like sl-build work and strongloop is listed in npm list -g.
Ubuntu 14 with node.js 4.1.2
By default somehow slc is not created or not added to PATH.
I solved this problem by adding symlink:
sudo ln -s /usr/lib/node_modules/strongloop/bin/slc.js /usr/bin/slc
A soft link named slc should have been created at /usr/local/bin which will point to strongloop binary.
Please verify if the following exists.
/usr/local/lib/node_modules/strongloop/bin/slc
If no, then strongloop did not get installed successfully, otherwise verify the existence of the softlink slc at /usr/local/bin/.
/usr/local/bin/slc -> /usr/local/lib/node_modules/strongloop/bin/slc
If yes, then /usr/local/bin needs to be added to the $PATH, otherwise create the softlink and verify that /usr/local/binin $PATH.
Looks like the Node installation that optionally comes with a Digital Ocean Droplet installs to a different location that's not in $PATH. I'm pretty sure that was the issue. Anyways, I fixed it by spinning up a server without Node pre-installed and followed this guide. Just use npm install -g strongloop instead of strong-cli because the latter has been deprecated.
Ubuntu 14.04 with node.js 4.4.2 (LTS) :
The installation of strongloop was done without any errors but slc was not added to the PATH. I solved this problem by adding the symlink:
sudo ln -s /usr/local/lib/node_modules/strongloop/bin/slc.js /usr/bin/slc
Actually i am not sure my case matches with yours but i want to share my experience. i got the same message anyway.
I realized that i had changed prefix of global packets before. Then i checked prefix with the following command.
$ npm config get prefix
/home/myUser/.node_modules_global
Then i added the path to PATH variable (but .profile, .bash_profile files will be better) in active command line window and problem solved.

I am using my corporate's laptop and am a new mac User (used Ubuntu before) :
OS: macOS Monterey Version 12.2
There are two accounts, administrator and mine - I don't have sudo rights. To install homebrew without administrator rights, I followed this Installation.
To install the node - I used brew install node. Both node -v and npm -v were working. When I restarted the laptop, I cannot find node/npm.
On running $ node -v, I get -bash: node: command not found (I changed my default terminal from zsh to bash and the output is the same for both of them)
I tried this solution but couldn't find nvm in the system. Am new to mac and I believe nvm is some kind of package manager like homebrew so this solution is not applicable to me (correct me if I am wrong).
How can I install things in my system without sudo rights and keep them permanently(like node)?
EDIT:
(After adding brew to the PATH) On running - brew list|grep node, I got - node
$ echo $PATH gives /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/parthkapadia/homebrew/bin
EDIT2:
Adding brew to path solved the issue, now I can even access node and npm (even after restarting). I used this site to add homebrew/bin to path (in zsh terminal)
The issue was homebrew's path. It was not added to the PATH variable.
When I restarted the system, homebrew was no longer in the PATH (as it was temporarily added probably when I installed it). As homebrew was not added to PATH, the terminal didn't recognize brew or any package installed using it like node or npm.
I solved it by adding Users/username/homebrew/bin to PATH. The steps I followed are -
cd - to move to the home directory
touch .zshrc to create .zshrc file as it didn't exist
nano .zshrc to open the file for editing
Added export PATH=$PATH:/Users/yourusername/homebrew/bin in the file (this appends homebrew/bin to the PATH variable)
Now the terminal can recognize brew and hence node and npm too.
Refer this for more detailed explanation on how to add to PATH in macOS.
Thanks to all the people who helped in the comments.
I am trying to change the version of nodejs using cmd n installed globally by yarn. Neither yarn is detected by sudo nor n.
Please help me to fix this:
When running the n command to change node version, it shows permission is denied by many files to be written by n
Two approaches to avoid permission issues without requiring use of sudo when running n:
install and run Node.js from your home folder using N_PREFIX and PATH (see also n-install which automates this)
if it is your personal computer, take ownership of the folders used with default install location of /usr/local
See the project README for more: https://github.com/tj/n
(Disclaimer: I am the maintainer of n.)
I have successfully installed loopback CLI using npm i -g #loopback/cli after that I'm trying to create app using lb4 app command terminal and it shows me Command 'lb4' not found.
Only lb app works for version 3 and 2 but I want to create application compatible with loopback version 4.
I had the same problem and solved it by updating to the latest version of Node.js (10.7 as of now). Then I reinstalled the LoopBack CLI with npm i -g #loopback/cli and the lb4 app command worked just fine. Also, I was executing all the commands as admin, in case it helps.
If you're having trouble creating a global link on Windows 10 (like I did).
Consider installing in the NodeJS project folder as a work-around.
Simply execute:
npm install #looback/cli --no-save
Notes:
This will install the cli without listing it as a dependency in your package.json.
This will allow you to run lb4 app only in the root folder of project where you ran the command.
This solution is not ideal since you'll have to do this for each project. However I figured it beats having to install a new version of NodeJS just for the installer to clear some cache/configuration that got messed up over a long time-period.
Upgrade your Node.JS to version 8.9 or higher.
It's a Prerequisites.
See the doc: https://loopback.io/doc/en/lb4/Getting-started.html#prerequisites
Also some time npm installs the JS module successfully but does not add in environment variable. Find the npm folder path (in my case C:\Users\user_name\AppData\Roaming\npm) and add into class path. After adding environment variable restart the command prompt.
I was also facing same problem. But then I ran the command using sudo and it worked. sudo npm i -g #loopback/cli.
sudo update-alternatives --install /usr/bin/lb4 lb4 /opt/nodejs/node-v19.1.0/bin/lb4 0
This command will be more useful to solve this problem.
You can replace nodejs path according to your system.(/opt/nodejs/node-v19.1.0/bin)
When I run sudo npm install -g express-generator:
/Users/myname/npm/bin/express -> /Users/myname/npm/lib/node_modules/express-generator/bin/express-cli.js
/Users/myname/npm/lib
└── express-generator#4.15.5
And when I run express:
express not found
Also, I thought it was interesting that when I run which npm:
/usr/local/bin/npm
That is the path.
It seems that whenever I try to install something like yeoman or this express generator globally, it never works.
It should also be noted that I am on an Mac running zsh.
Most likely your npm bin directory is not in the path. Try to list the files in that directory by ls -l /usr/local/share/npm/bin/.
If you find the express file, you can add that directory to the path by export PATH=/usr/local/share/npm/bin:$PATH. If not, most likely something went wrong with your installation and you can try installing the module again.
Running this in the command line:
export PATH=/usr/local/bin/npm:$PATH
Fixed the issue...for now. I'm not totally sure why that worked.
This affects Homebrew users using Node.js & npm
When you install Node.js using Homebrew it does not put npm on the PATH for you, however it suggests that you should do so.
Homebrew doesn't modify the user's environment or dotfiles. However, brew install node does print a message suggesting the user add that path to their PATH.

I am having this error with node. Running Debian 7 (Wheezy) a VPS.
I have this error if I for example run this command (in the directory of the .js)
node sell.js
or
screen node sell.js
They both don't work, because I am getting this error:
-bash: /usr/sbin/node: No such file or directory
Can somebody help me?
As in #Quentin's answer, the name of the executable may be incorrect. In many cases, what got installed was nodejs, not node. The line below creates a symbolic link that points to nodejs from where your system looks when you type node. It is a work-around - an alternative to simply typing nodejs
sudo ln -s /usr/bin/nodejs /usr/sbin/node
The Debian package for NodeJS is called nodejs and installed the executable /usr/bin/nodejs.
node is the wrong program, it is for ham radio operations, and your install of it appears to be broken anyway).
I ran the command:
sudo apt-get install nodejs-legacy
and nodejs worked again!
Maybe something wrong happened during your node's installing.
And system environment variable shows the command "node" referes to /usr/sbin/node .
Try download node linux binaries from official. Rename and put it in /usr/sbin after extracting the source. Of course you can put it in another folder as long as you update the system environment variables.
