Question

我有一个简单的脚本：

require 'rubygems'
require 'mechanize'
p 'Success!'

当我运行脚本时，我得到：

/Users/.../.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mechanize.rb (LoadError)
from /Users/.../.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from test.rb:2:in `<main>'

在绝望中我安装了RVM并从系统1.8.7更新了ruby。然而，我仍然遇到与安装rvm之前相同的错误。我现在正在跑步：

mute:nfg ..$ ruby -v
ruby 1.9.3p385 (2013-02-06 revision 39114) [x86_64-darwin10.8.0]

irb报告相同：

1.9.3p385 :001 > require 'rubygems'
 => false 
1.9.3p385 :002 > require 'mechanize'
LoadError: cannot load such file -- mechanize
from /Users/../.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from /Users/../.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from (irb):2
from /Users/../.rvm/rubies/ruby-1.9.3-p385/bin/irb:16:in `<main>'

我已经从项目目录中多次使用sudo重新安装了机械化。

我试过手动要求宝石及其完整路径。

mute:nfg ..$ ruby -l ~/.gems/gems/mechanize-2.5.1/lib/mechanize.rb
/Users/../.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mime/types (LoadError)
from /Users/../.rvm/rubies/ruby-1.9.3-p385/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from /Users/../.gems/gems/mechanize-2.5.1/lib/mechanize.rb:4:in `<main>'

（我也试过安装mime-types。）

RVM列出了精美的宝石：

mute:nfg ..$ rvm all do gem list
*** LOCAL GEMS ***
...
libxml-ruby (2.3.3, 1.1.2)
mechanize (2.5.1)
mime-types (1.21, 1.19)
...

和宝石一样：

mute:nfg ..$ gem list
*** LOCAL GEMS ***
...
libxml-ruby (2.3.3, 1.1.2)
mechanize (2.5.1)
mime-types (1.21, 1.19)
...

奇怪的是，$ GEM_PATHs ~/.rvm/gems/ruby-1.9.3-p385，~/.rvm/gems/ruby-1.9.3-p385@global和~/.rvm/gems/ruby-1.9.3-p385@project大部分都是空的（第一个中有两个宝石，最后一个中没有宝石）。但是，GUI JewelleryBox确认所有三个gemset都包含Mechanize。

编辑：这是gem env的结果：

RubyGems Environment:

有人可以帮忙吗？

您的环境设置为使用宝石的自定义路径，这会在您安装到PATH

中不可用的地方时混淆rubygems

运行rvm get head并仔细阅读输出，它会警告您*gemrc中违反rubygems / RVM的条目

无法在OSX 10.6上加载此类文件 - mechanise.rb（LoadError）
