ruby-on-rails - NoMethodError: private method `open' called for Gem::Package:Class 安装 rake (10.0.3) 时出错，Bundler 无法继续

Question

我正在尝试处理从 github 同步的 ruby​​ on rails 项目。即使 rake-10.0.3 安装成功，“bundle 安装”也会失败。我是 Rails 新手，不知道如何继续。我用谷歌搜索了错误，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。

这就是我想要做的......请帮忙。

您应该首先更新 Rubygems:

gem update --system

然后更新 Bundler:

gem install bundler
