Ruby on rails NoMethodError：私有方法`打开'；调用Gem:：Package:Class安装rake（10.0.3）时出错，Bundler无法继续

我正在尝试一个从github同步的RubyonRails项目。即使rake-10.0.3安装成功，“捆绑安装”也会失败。我是rails新手，不知道如何继续。我搜索了错误，并尝试按照解决方案的建议安装不同版本的rake，但没有帮助

这就是我要做的。。。请帮忙

谢谢大家!

您应该首先更新Rubygems：

gem update --system

然后更新绑定器：

gem install bundler

试试这个：你在使用rvm还是ebenv？您好，谢谢您的回答，很抱歉延迟回复。在我卸载并重新安装ruby on rails之后，它得到了解决……为了后代：有了完全相同的问题，这个解决方案解决了它，这与大多数其他东西不同。你也确实需要第二步，即使你已经安装了相同版本的Bundler。
