Can't use nvm from bash script

Question

I am trying to write a shell script to automate my dev environment set-up (install python, nvm, node, mongo etc...). I am using nvm to install Node. It tells you to close and reopen your terminal to start using the nmv command. I tried to source .bashrc and .profile to make the command available right away so I can continue running the script with nvm install, but it doesn't work.

Here is the segment of my script related to installing NVM / Node:

#install nvm and latest node version # sourcing profile and bashrc is not working here. nvm does not execute the next two lines to install node.  wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash source ~/.profile source ~/.bashrc nvm install 5.0 nvm alias default node 

I get these messages, but please note that I've already run the script and NVM / Node are already installed and working. I can also use nvm and node in the same terminal I run the script from after it completes. It just doesn't work in the script.

=> Downloading nvm from git to '/home/myDir/.nvm' => fatal: destination path '/home/myDir/.nvm' already exists and is not an empty directory. fatal: Not a git repository (or any of the parent directories): .git fatal: Not a git repository (or any of the parent directories): .git  => Source string already in /home/myDir/.bashrc => Close and reopen your terminal to start using nvm ./install-programs.sh: line 27: nvm: command not found ./install-programs.sh: line 28: nvm: command not found 

Answer 1

if you have nvm running on the main shell, you just need to add:

export NVM_DIR=$HOME/.nvm; source $NVM_DIR/nvm.sh; 

in your script

Answer 2

Here is what worked for me.

First install nvm (once and separately) using SSH or console:

$ wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash 

Then in your script, loading your profile as follows:

. ~/.nvm/nvm.sh . ~/.profile . ~/.bashrc 

And with some luck nvm should become available inside the script.

nvm install 4.4.2 

Tada!
