我创建了一个rails应用程序，然后从另一个应用程序（包括spec文件）导入Gemfile。当我运行rspec时，会出现以下错误。我做错了什么

我也犯了同样的错误。这很奇怪，因为在其他类似的项目中，rspec工作得很好。我用rvm安装了旧版本的ruby（2.2.3），安装了gems，它运行正常

rvm install ruby-2.2.3
rvm ruby-2.2.3
gem install rspec
gem install rspec-its
gem install capybara
gem install poltergeist

然后rspec开始工作

如果有帮助，请写下：）

我所要做的就是删除Gemfile.lock文件，然后进行捆绑安装。不知何故，新的Ruby版本与Nokogiri版本1.6.7.2发生冲突。

是否安装了Nokogiri gem？是否在Windows上运行Rails？
