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

[snowe2010]

• 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

What zsh options do you have? Specifically what's the output of setopt? zsh options often break tools that don't run in a subshell.

[ljharb]

I'd also try disabling omz; it will likely work fine - which implicates one of omz's options.

I disabled oh-my-zsh and still get the error

[snowe2010]

Oh wait, nope. I had to start a new session, not just source zshrc. Looks like disabling oh-my-zsh got rid of the error. But I need a way for this rakefile to work for anyone anywhere.

[ljharb]

I will try to reproduce it, but the fastest method is for you to do a binary search on that option list, until you find out exactly which option is breaking it - then I can quickly work around it.

[snowe2010]

Ok, give me a few minutes then.

[ljharb]

(You can ofc skip the stock zsh options)

[snowe2010]

ofc? and I tried unsetting every option but I still get the error

```/Users/tylerthrailkill/.nvm/nvm.sh: line 30: cd: -q: invalid option
cd: usage: cd [-L|-P] [dir]
N/A: version "4.5.0 -> N/A" is not yet installed.

You need to run "nvm install 4.5.0" to install it before using it.

Do I need to unset the options in omzsh somehow and then create a new session to test each option?

[snowe2010]

and also, if I do disable oh-my-zsh I get these errors.

N/A: version "4.5.0 -> N/A" is not yet installed.

which I would think shouldn't be happening.

[snowe2010]

Ok, it's the zsh-nvm plugin doing something.

[ljharb]

("ofc" means "of course")

If you uninstall zsh-nvm, with your normal omz, what happens?

[snowe2010]

Everything works perfectly if I remove zsh-nvm from plugins=(otherpluginshere...)

[ljharb]

In that case, it sounds like it's a bug in zsh-nvm, and not in this project - can you file it there, and link it, and close this one after doing that?

[snowe2010]

Yes I can. Thank you for your help.
