我收到上面的错误..

如何解决这个问题?？

Answer 1

这是因为您安装的RubyGems对于您的Rails版本来说太新了。降级(并重新运行update_rubygems)或将Rails升级到2.3.11。

Answer 2

解决方案相当简单。只需运行以下命令返回到rubygems的前一个版本，您应该就可以了：

$ gem install rubygems-update -v='1.4.2'
$ gem uninstall rubygems-update -v='1.5.0'
$ update_rubygems

Answer 3

这可能是因为您已经安装了rails 3，但正在尝试运行rails 2.3.4应用程序。我以前遇到过这个问题，解决方案是删除rails 3，因为这个依赖是rails 3的一个依赖项，而不是2.3.4
