在rails交互式shell(rails c
)中,当我运行No such file to load -- Mechanize'
时收到错误消息:require 'mechanize'
。
奇怪的是,当我在ruby shell(require 'mechanize'
)上输入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

此致
答案 0 :(得分:3)
将此添加到Gemfile
gem 'mechanize'
然后在shell上执行此命令
bundle
