Rbenv default ruby issue on install

[abuxton]

I am trying to install MDL v0.11.0

i get the following error during install

pre-commit
[INFO] Installing environment for git://github.com/markdownlint/markdownlint.
[INFO] Once installed this environment will be reused.
[INFO] This may take a few minutes...
An unexpected error has occurred: CalledProcessError: command: ('/usr/local/bin/bash', '/Users/abuxton/.rbenv/shims/gem', 'build', 'mdl.gemspec')
return code: 1
expected return code: 0
stdout: (none)
stderr:
    rbenv: version `default' is not installed (set by RBENV_VERSION environment variable)

seems to be the same issue as #369 on a previous version of pre-commit
pre-commit.log https://gist.github.com/abuxton/d29e6265f3230f838a746d7a5defd5e3

i have tried, ensuring local rbenv, I have tried pre-commit clean/uninstall and reinstall to no success, mdl will brew install mdl successfully and works fine.

ah yeah, this has regressed because it's difficult to test! pre-commit ~correctly identified that you're using shims globally so it shouldn't necessarily trust that ruby, but then used it anyway 😆 -- this if here needs to also apply to 'default':

pre-commit/pre_commit/languages/ruby.py

Line 43 in 59acc7e

if language_version == 'system':

actually hmm this seems really strange -- pre-commit should still be creating an rbenv shim in that case so my suggested patch above isn't quite correct

[asottile]

@abuxton can you try out the patch in #1700 -- it fixed the case I tried locally but I'm not 100% it solves your usecase

I had exactly the same issue today in AWS CodeBuild.

Tried the fix #1700 and it solves it for me.

Now that this has been merged in, when is the next planned package release?

if you look at the release history, nothing is "planned", I maintain this in my free time :) if you or your company depend on this package I'd recommend sponsoring
