scss-lint fails

[shawnacscott]

Any time I commit a scss file, pre-commit fails with this error:

pre-commit: Stopping commit because of errors.
sh: scss-lint: command not found

I am using pre-commit with a YAML configuration file like this:

:checks:    [common, rails, rspec_focus, pry, ruby_symbol_hashrockets, tabs, console_log, debugger, tabs, whitespace, merge_conflict, rubocop, scss_lint]
:warnings:  []

are you using version manager like rvm or chruby?

[shawnacscott]

I do use chruby.

@postmodern / @havenwood given https://github.com/jish/pre-commit/blob/master/templates/hooks/automatic I assume the command would be ~ sh -c ruby -rrubygems -rpre-commit -e "PreCommit.run" - question: how to identify which ruby would be run and install the missing gem(scss-lint) for it?

btw. if there is more to do to support chruby than just calling ruby in the subprocess, can you open a PR for the template?

[postmodern]

As @mpapis informed me, the command is being ran in a plain shell from git? As long as auto.sh gets loaded by the shell, auto-switching should take; before the first command for zsh and after the first command for bash. Maybe invoking sh -l ... would work?

[mpapis]

as discussed in irc sh -l is out of question as it would slow down every commit, maybe new template could be an option where the auto-switching is loaded and then call to ruby is made ... or maybe chruby could provide this script and our automatic template would use it

[postmodern]

Or since git does not preserve the current shell environment, maybe install scss-lint globally under system ruby?

[mpapis]

what would be the flow for chruby to do that?

[postmodern]

chruby system
sudo gem install scss-lint
# scss-lint should now be accessible to git and cron

[mpapis]

assuming there was a system ruby, this is complicated, is there a "default" ruby in chruby like it is in RVM?

[postmodern]

The default ruby is system ruby. You can configure a default ruby via the shell configuration or via .ruby-version. However, since git blows away the current environment, the default ruby may not be the user selected ruby.

[mpapis]

this sounds like nightmare, maybe we could promote an description/wiki that shows what to do, maybe selecting one ruby and setting it in git config --global pre-commit.ruby="chruby..."?

[postmodern]

It is not a nightmare to install a gem globally. system ruby exists for a reason. Don't fear the system ruby, don't fear your own system.

[mpapis]

assuming there is a system ruby, I know it's really common this days, but still not a base requirement for a linux system
