无法在OSX 10.6上加载这样的文件--mechanize.rb(LoadError)

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1.8.7系统更新了ruby。然而，我仍然会遇到与安装rvm之前相同的错误。我现在正在运行：

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和不使用sudo重新安装mechanize。

我尝试过手动要求宝石，以及它的完整路径。

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类型。(

RVM列出宝石罚款：

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)
...

宝石也是如此：

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_PATH的~/.rvm/gems/ruby-1.9.3-p385、~/.rvm/gems/ruby-1.9.3-p385@global和~/.rvm/gems/ruby-1.9.3-p385@project看起来大多是空的(第一个有两个宝石，最后一个都没有(。但是，GUI JewelleryBox确认所有三个宝石集都包含Mechanize。

编辑：以下是gem-env:的结果

有人能帮忙吗？

您的环境被设置为使用gems的自定义路径，当您安装到PATH 中不可用的位置时，这会混淆rubygems

运行rvm get head并仔细阅读输出，它会警告您*gemrc中的条目会破坏rubygems/RVM
