每当我开始乘客时，它都会引发一个奇怪的错误

Passenger 4.0.19运行良好，仍然在ruby 2.0.0-p0上运行良好，但未在ruby 2.0.0-p247上运行。我使用rvm升级了ruby版本，因为我的rails应用程序中的其他gems无法正常工作，现在乘客在ruby版本升级后无法正常工作。以前有人见过这个错误吗？
答案 0 :(得分：1)
我在虚拟专用服务器上使用rails应用程序时出现此问题，我可以运行webrick但不会运行乘客，瘦或独角兽而不会

这最终成为旧版rubygems-bundler中的一个错误。这为我解决了这个问题。
gem update rubygems-bundler
希望这有帮助。

可能很奇怪，但请再次尝试gem install bundler然后bundle install
