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:

有人可以帮忙吗?
答案 0 :(得分:1)
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
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
