创建新的Rails应用程序时出现NoMethodError

Question

创建新的Rails文件夹（带有rails new my_app ）时出现此错误：

http://cl.ly/image/3S071x1l0w3J

-> NoMethodError: private method 'open' called for Gem::Package:Class
An error occured while installing rake (10.0.3), and Bundler cannot continue.
Make sure that 'gem install rake -v '10.0.3' succeeds before bundling.

有什么帮助吗？
