You have already activated rake 0.9.2.2, but your Gemfile requires rake 0.9.2. C
onsider using bundle exec.

这可能是因为您的系统上有更新的 Rake 版本。您可以按照错误所述执行操作：bundle exec rake db:migrate在您的应用程序上下文中运行 rake（rake 0.9.2），或者只是删除您的 Gemfile.lock 并再次捆绑。

我也遇到了同样的情况，bundle exec当然在终端中工作，但 RubyMine 不听。事实证明，globalgemset 使用了rake比我的“本地”gem set 更新的版本，我最终rake从globalgemset 中卸载以使 RubyMine 再次高兴（在重新启动之后）。
