请首先删除Gemfile.lock文件以确保捆绑包重建所有依赖项，并首次安装所有gem as，然后重新创建文件，然后：

$ bundle install

请验证nokogiri gem是否已显示在Gemfile.lock中。然后，为确保nokogiri gem安装正确，请键入：

$ bundle show nokogiri
/path/to/nokogiri/gem

上面的I命令显示了一个错误，其他人无法找到gem'nokogiri'，这意味着您的系统设置不正确。所以请不要使用根帐户，而使用简单用户作为项目的持有者。要将project gem版本彼此分离，请使用

rvm

将gems安装到其编写的gems中。

删除Gemfile.lock并重试，请不要使用root帐户，使用

rvm

将gems安装到gems删除Gemfile.lock没有帮助。。。其他建议？谢谢bundler再次创建了Gemfle.lock，请验证其中是否有nokogiri gem？是的gem列在Gemfile.lock中
