Question

当系统宝石不在$ PATH中时，我遇到了使用自制软件查询系统宝石的问题。

这是我的gem env，表明我的宝石安装在我的.rvm / gems目录中：

    RubyGems Environment:
  - RUBYGEMS VERSION: 2.4.5
  - RUBY VERSION: 2.2.2 (2015-04-13 patchlevel 95) [x86_64-darwin14]

     - /opt/X11/bin
     - /Users/scott/.rvm/bin
     - /Users/scott/.composer/vendor/bin
     - /usr/local/sbin

现在这是我不断收到的各种命令的错误信息（特别是来自brew services start httpd22）：

Error: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/nokogiri-1.6.1 for inspection.

了解它如何看待Ruby＆amp;的系统版本。宝石？我安装了XCode并且是最新的。

brew doctor没有结果，brew update已准备好酿造。

我正在使用OS 10.10.3。我忘记了任何事情，只要问一下。

修改

这是我的.zshrc $ PATH导出：

export PATH="$PATH:$HOME/.composer/vendor/bin"
export PATH="$PATH:/usr/local/sbin"
export PATH="$PATH:$HOME/.rvm/bin"

编辑2

$GEM_HOME

/Users/scott/.rvm/gems/ruby-2.2.2

$GEM_PATH

/Users/scott/.rvm/gems/ruby-2.2.2:/Users/scott/.rvm/gems/ruby-2.2.2@global

思想？

Answer 1

看着brew：

https://github.com/Homebrew/homebrew/blob/master/bin/brew

https://github.com/Homebrew/homebrew/blob/master/bin/brew#L22

所以brew正在扰乱GEM_PATH并做自己的事情。

找到答案，系统rubygems.rb引用了错误版本的Ruby。更多详情：https://github.com/Homebrew/homebrew/issues/31220
