ruby - 我在 ruby​​ 中安装 Mechanize 时的一些问题

Question

我在 ubuntu 12.04 上使用 ruby​​ 1.8.7 和 ruby​​gem 1.8.15

首先，我输入sudo gem install mechanize --no-ri --no-rdoc

它似乎运作良好。

WARNING: ntlm-http-0.1.1 has an invalid nil value for @cert_chain

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

它只是行不通

./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

有人可以帮助我吗？

将您的文件重命名为“mechanize-test.rb”或其他名称以避免与库混淆。看起来1.8的require行为很奇怪。
