在 rails 交互式 shell ( rails c) 中，我收到一条错误消息：No such file to load -- Mechanize'当我运行require 'mechanize'.

奇怪的是，当我进入require 'mechanize'ruby​​ shell ( irb) 时，我没有收到任何错误。

示例输出如下所示：

    rails c 
    Loading development environment (Rails 4.0.2)
    irb(main):001:0> require 'mechanize'
    LoadError: cannot load such file -- mechanize

将此添加到 Gemfile

gem 'mechanize'

然后在shell上执行这个命令

bundle
