nvm: Attempting to source nvm from within a ruby script does not seem to use parent shell

• Operating system and version: MacOS 10.12.5

• nvm debug output: no debug output, the script won’t load

• nvm ls output: no ls output, the script won’t load

• How did you install nvm? (e.g. install script in readme, homebrew): I don’t remember. Probably zsh-nvm

• What steps did you perform? I’ve added

  system %{
    . ~/.nvm/nvm.sh
    nvm use 4.5.0
    npm install
  }

to a Rakefile. Running the rakefile results in the following error:

/Users/tylerthrailkill/.nvm/nvm.sh: line 27: cd: -q: invalid option
cd: usage: cd [-L|-P] [dir]
N/A: version "4.5.0 -> N/A" is not yet installed.

With my own debugging I don’t understand why -q is not a valid option, since I’m running in a zsh, and I’ve verified SHELL is zsh.

• What happened? nvm won’t load

• What did you expect to happen? nvm to load, since I’m running the rakefile from a zsh, it should run consistently in that shell.

• Is there anything in any of your profile files (.bashrc, .bash_profile, .zshrc, etc) that modifies the PATH? Yes, lots, but I’ve verified through modifying the nvm.sh file to printenv to show that I’m in the proper shell with the property stuff set. Here is that output
