bash doesn't load node on remote ssh command

Question

Excuse me if the subject is vague, but I tried to describe my problem to the best of my possibilities. I have my raspberry pi which I want to deploy to using codeship. Rsyncing the files works perfectly, but when I am to restart my application using pm2 my problem occurs.

I have installed node and pm2 using the node version manager NVM.

ssh [email protected] 'source /home/pi/.bashrc; cd project; pm2 restart app.js -x -- --prod'0 min 3 sec
bash: pm2: command not found

I have even added:

shopt -s expand_aliases in the bottom of my bashrc but it doesn't help.

How can I make it restart my application after I have done a deploy? Thanks in advance for your sage advice and better wisdom!

EDIT 1: My .bashrc http://pastie.org/10529200 My $PATH: /home/pi/.nvm/versions/node/v4.2.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games

EDIT 2: I added /home/pi/.nvm/versions/node/v4.2.0/bin/pm2 which is the full path to pm2 and now I get the following error: /usr/bin/env: node: No such file or directory

It seems that even if I provide the full path, node isn't executed.

Answer 1

Like Sukima said, the likelihood is that this is due to an environment issue - SSH'ing into a server does not set up a full environment. You can, however, get around much of this by simply calling /etc/profile yourself at the start of your command using the . operator (which is the same as the "source" command):

ssh [email protected] '. /etc/profile ; cd project; pm2 restart app.js -x -- --prod'

/etc/profile should itself be set up to call the .bashrc of the relevant user, which is why I have removed that part. I used to have to do this quite a lot for quick proof-of-concept scripts at a previous workplace. I don't know if it would be considered a nasty hack for a more permanent script, but it certainly works, and would require minimal modification to your existing script should that be an issue.

Answer 2

For me I have to load :nvm as I installed node and yarn using :nvm

To load :nvm when ssh remote execution, we call

ssh :user@:host 'source ~/.nvm/nvm.sh; :other_commands_here'

Answer 3

You should enable some environment values by "source" or dot command ".". Here is an example.

ssh [email protected] '. /home/pi/.nvm/nvm.sh; cd project; pm2 restart app.js -x -- --prod'
