为什么我的Ruby Git脚本钩子运行错误的$ PATH? [英] Why is my Ruby Git script hook run with the wrong $PATH?
问题描述
pre-commit
钩子: !/ usr / bin / env ruby
放RUBY_VERSION
puts`echo $ PATH`
退出(1)
1.8.7 us / / / bin -2.0.0-p195@global/bin:/Users/mgoerlich/.rvm/rubies/ruby-2.0.0-p195/bin:/Users/mgoerlich/.rvm/bin:/用户/ mgoerlich / ADT-bundle- MAC-x86_64-20130219 / SDK /平台的工具:/用户/ mgoerlich / ADT-束-MAC-x86_64-20130219 / SDK /工具:在/ usr / local / bin目录:在/ usr / local / sbin中:/用户/ mgoerlich / .dotfiles /斌:在/ usr / bin中:/ bin中:/ usr / sbin目录:/ sbin目录:在/ usr / bin中/ core_perl:/用户/ mgoerlich /斌:在/ usr / local / share下/ NPM /斌:在/ usr /本地/ share / npm / bin
似乎运行错误的Ruby版本,因为 $ PATH
与bash或zsh或sh不同。似乎git正在操纵 $ PATH
。手动运行时,我得到这个:
$ .git / hooks / pre-commit
2.0.0 $ b美元/ /bin:/Users/mgoerlich/.rvm/bin:/Users/mgoerlich/adt-bundle-mac-x86_64-20130219/sdk/platform-tools:/Users/mgoerlich/adt-bundle-mac-x86_64-20130219/sdk /tools:/usr/local/bin:/usr/local/sbin:/Users/mgoerlich/.dotfiles/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/bin/core_perl: / users / mgoerlich / bin:/ usr / local / share / npm / bin:/ usr / local / share / npm / bin
在提交钩子的输出中,前面有两个路径,其中一个 / usr / bin
其中放置了系统Ruby的可执行文件。 / p>
这是一个已知的行为吗?我可以操纵吗?我知道我可以在shebang中指定正确的Ruby版本的完整路径,但这不是我想要的。
我不想使用 env
而不是ruby或rvm包装器的固定路径的原因是这是一个Team Project,而不是Team中的每个人都在使用RVM。
我的最终解决方案是将自己的包装脚本添加到该项目中。
所有客户端git钩子在$ code> $ PROJECT / bin / hooks 中,都是ruby脚本。
现在,我刚刚把所提到的包装器放在那里,并为所有钩子的 $ PROJECT / .git / hooks
中的包装器创建了一个符号链接。
脚本检查是否使用RVM,如果这样修复了 $ PATH
var,如果有$ code> .ruby-version 和/或 .ruby-gemset
项目根中的文件加载了相应的版本/ gemset。
然后它将运行相应的ruby脚本
这是包装器,以防您感兴趣:
#!/ bin / bash
如果[-d$ HOME / .rvm / bin];然后
PATH =$ HOME / .rvm / bin:$ PATH
[[-s$ HOME / .rvm / scripts / rvm]]&&源$ HOME / .rvm / scripts / rvm
如果[-f.ruby-version];然后
rvm使用$(cat .ruby-version)
fi
如果[-f.ruby-gemset];然后
rvm gemset使用$(cat .ruby-gemset)
fi
fi
rubybin / hooks / $(basename$ 0)。 $ b
所以,我会得到我的rvm版本/ gemset和其他所有他们在路径中的ruby版本,大家都快乐。
I'm using RVM. I wrote a Git pre-commit
hook for a project:
#!/usr/bin/env ruby
puts RUBY_VERSION
puts `echo $PATH`
exit(1)
which outputs this when run by Git:
$ git ci -m 'foo'
1.8.7
/usr/libexec/git-core:/usr/bin:/usr/local/heroku/bin:/Users/mgoerlich/.rvm/gems/ruby-2.0.0-p195@global/bin:/Users/mgoerlich/.rvm/rubies/ruby-2.0.0-p195/bin:/Users/mgoerlich/.rvm/bin:/Users/mgoerlich/adt-bundle-mac-x86_64-20130219/sdk/platform-tools:/Users/mgoerlich/adt-bundle-mac-x86_64-20130219/sdk/tools:/usr/local/bin:/usr/local/sbin:/Users/mgoerlich/.dotfiles/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/bin/core_perl:/Users/mgoerlich/bin:/usr/local/share/npm/bin:/usr/local/share/npm/bin
It seems to run with the wrong version of Ruby because $PATH
is not the same as in bash or zsh or sh. It seems like git is manipulating $PATH
. When run manually, I get this:
$ .git/hooks/pre-commit
2.0.0
/usr/local/heroku/bin:/Users/mgoerlich/.rvm/gems/ruby-2.0.0-p195@global/bin:/Users/mgoerlich/.rvm/rubies/ruby-2.0.0-p195/bin:/Users/mgoerlich/.rvm/bin:/Users/mgoerlich/adt-bundle-mac-x86_64-20130219/sdk/platform-tools:/Users/mgoerlich/adt-bundle-mac-x86_64-20130219/sdk/tools:/usr/local/bin:/usr/local/sbin:/Users/mgoerlich/.dotfiles/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/bin/core_perl:/Users/mgoerlich/bin:/usr/local/share/npm/bin:/usr/local/share/npm/bin
In the output of the commit hook, there are two paths prepended, one of them /usr/bin
where the system Ruby's executable is placed.
Is this a known behavior? Can I manipulate that somehow? I know I could specify the full path to the correct Ruby version in the shebang, but this is not what I want.
The reason i didn't wanted to use env
instead of a fixed path to ruby or a rvm wrapper was that this is for a Team Project and not everyone in the Team is using RVM.
My final solution was to write my own wrapper script an add it to that project.
All client-side git hooks 're living in $PROJECT/bin/hooks
, all of them ruby scripts.
Now, i've just put that mentioned wrapper in there, and created a symlink to that wrapper in $PROJECT/.git/hooks
for all the hooks.
The script check's if RVM is used and if so fixes the $PATH
var and if there are .ruby-version
and/or .ruby-gemset
files in the project root it loads the according version/gemset.
Then it'll run the according ruby script Here's the wrapper in case you're interested:
#!/bin/bash
if [ -d "$HOME/.rvm/bin" ]; then
PATH="$HOME/.rvm/bin:$PATH"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
if [ -f ".ruby-version" ]; then
rvm use "$(cat .ruby-version)"
fi
if [ -f ".ruby-gemset" ]; then
rvm gemset use "$(cat .ruby-gemset)"
fi
fi
ruby "bin/hooks/$(basename "$0").rb"
So, i'll get my rvm version/gemset and everybody else the ruby version they have in their PATH, and everyone is Happy.
