How to run npm through ssh

After installing npm according to https://nodesource.com/blog/installing-node-js-tutorial-using-nvm-on-mac-os-x-and-ubuntu/ , 3 lines were added at the end of ~/.bashrc to load nvm tools.

When connecting to that server with ssh, npm --version outputs 5.5.1 as expected.

But when running remotely :

ssh server /bin/bash -l -c "npm --version"

I get :

--version: npm: command not found

What is the correct way to have npm available when running it remotely in one line?

I have my nvm.sh file in /etc/profile.d with the following content:

export NVM_DIR = "/ usr / local / nvm"
[-s "$ NVM_DIR / nvm.sh"] && \. "$ NVM_DIR / nvm.sh" # This loads nvm
[-s "$ NVM_DIR / bash_completion"] && \. "$ NVM_DIR / bash_completion" # This loads nvm bash_completion

So to connect by ssh from another server I can do it by increasing previously . /etc/profile.d/nvm.sh, that is:

ssh -t "server" ". /etc/profile.d/nvm.sh && npm -v"

Please refer to this question: https://apple.stackexchange.com/questions/12993/why-doesnt-bashrc-run-automatically

It has both a solution and an explanation for the root cause of your problem. Normally you shouldn't have to specify anything at the ssh level - shell initialization is to supposed to be automatic and ssh is supposed to open an interactive shell.

The problem is as you may suspect, your .bashrc is not being sourced. You had the right idea by adding the -l flag but what you really need in this case is the -i flag to spawn an interactive shell, in-turn sourcing your .bashrc prior to command execution.

ssh -t "server" 'bash -i -c "npm --version"'

man ssh

If command is specified, it is executed on the remote host instead of a login shell.

-t Force pseudo-terminal allocation.

man bash

When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist.
