Ruby没关系，Rails没问题，但是“rails console” 需要帮忙感谢

Answer 1

看起来你错过了ruby版本中的文件。你刚刚更新到OS X 10.7吗？您可能需要重新安装Rails。一如既往，这可以通过以下方式完成：

sudo gem install rails

抱歉，我无法提供更多帮助。

Answer 2

建议使用bundler来管理项目中的gem。

如果你把

 source 'http://rubygems.org'

 gem 'rails', '3.0.9'

Gemfile中的

（另请参阅http://gembundler.com/）

然后

 bundle install

将安装正确版本的rails和

 bundle exec rails console

将启动您的控制台。 bundle exec rails server将启动服务器等。

您可能还想考虑使用rvm来安装和管理您的红宝石（如果您还没有） - http://beginrescueend.com/

Ruby，Rails控制台以错误开始...需要帮助
