一些问题，当我在红宝石

安装机械化我在Ubuntu 12.04使用Ruby 1.8.7和rubygem 1.8.15一些问题，当我在红宝石

首先，我在sudo gem install mechanize --no-ri --no-rdoc

它似乎运作良好类型。

Building native extensions. This could take a while...

Successfully installed unf_ext-0.0.5 
Successfully installed unf-0.0.5 
Successfully installed domain_name-0.5.4 
Successfully installed mechanize-2.5.1 
7 gems installed

然后我写了我的第一个程序

require 'rubygems' 
require 'mechanize' 

agent = Mechanize.new

这是行不通的

./mechanize.rb uninitialized constant Mechanize (NameError) 
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in  gem_original_require' 
    from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in `require' 
    from mechanize.rb:2

有人能帮助我吗？

将文件重命名为'mechanize-test.rb'或其他内容以避免与库混淆。它看起来像1.8的require行为奇怪。

太棒了！它的工作原理。 – user1668903

它不需要行为不当，但轨道加载类的方式文件名预计是类名，所以当你有mechanize.rb它期望找到它的类名机械化，因此导致未初始化的常量异常 – bjhaid

@bjhaid - 实际上问题是1.8从'.'加载mechanize.rb，而不是由于'LOAD_PATH'问题引起的gem文件夹问题。这不是铁轨问题，这里没有铁轨。 – pguardiario
