ruby-on-rails - Rails - 500 内部服务器错误

Question

当我尝试启动一个旧应用程序时出现以下错误，但似乎无法查明问题所在。我收到“call_with_exception”错误，谷歌搜索没有提供任何帮助。谁能指出我正确的方向？我正在使用 Rails 2.3.5、Ruby 1.8.7 并使用 RVM。

$ script/server 
=> Booting Mongrel
=> Rails 2.3.5 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

Answer 1

首先，您可能已经知道，请确保您使用了正确的 ruby​​ 版本

rvm list #find the right ruby-1.8.7 version you have used to get this app running back then

然后(例如，如果您使用 p249)

rvm ruby-1.8.7-p249

如果这不起作用，现在是尝试一下并调试 rails 核心的好时机。 “put”方法在这里有很大帮助。

在执行此操作之前，我个人首先将我的 Rails 卡住到我的应用程序中，然后直接在那里进行任何更改(不推荐，大多数时候我编写混入，但不是所有时候)。

卡住 rails gem :

rake gems:unpack

然后

rake gems:install
