在我的应用程序中，在过去的几天里，我无法再运行rails server/rails s甚至bundle exec rails server命令。它以前像魅力一样运行。

我尝试使用 git 还原更改，但没有运气，我尝试了我能想到的所有可能的礼仪。我使用 ruby​​mine，但使用 Terminal 时同样的问题。

当我运行时：

ma@SL510:~/ts$ rails server

我得到以下错误堆栈跟踪：

    from script/rails:6:in `<main>'

我不知道我该如何解决这个问题，让 rails server 命令再次运行！任何帮助将不胜感激！

ps：如果我需要提供更多信息，请告诉我。谢谢。

感谢 Jef 创建了一个新的 gemset 并使用它，然后：

gem install unicorn

修复了该命令的问题:)

您可以尝试创建一个全新的 gemset（并使用它），然后bundle install让 Bundler 安装 Gemfile 中列出的 gem。堆栈跟踪似乎表明您正在使用全局 gemset，这是一个非常糟糕的主意。
