NodeJS Child Process EXEC Command Failed with NVM Permission denied OSX

Question

I am attempting to launch nvm within a child process in Nodejs on OSX However in doing so, I am getting the following error: /bin/sh: /Users/miker/.nvm/nvm.sh: Permission denied

Answer 1

~/.nvm/nvm.sh is not executable script, it is meant to be "sourced" (not run in a separate shell, but loaded and executed in the current shell context).

Trying to run it as if it were executable would result in a permission error, because it doesn't have executable permissions.

I don't know if it's going to work, but try this instead:

echo $NVM_DIR && source $NVM_DIR/nvm.sh && nvm use VERSION && npm install

You may have to explicitly set the shell option for child_process.exec() to make sure that the command line is run in a "full" shell (like /bin/bash).
