推荐答案

也许您不小心在Rails 3.1应用程序上加载了Rails 3.0.x?

Maybe you're accidentally loading Rails 3.0.x on a Rails 3.1 application?

如果您生成一个添加了config/initializers/wrap_parameters.rb的Rails 3.1应用程序，然后尝试使用Rails 3.0.x引导它，它将无法正常工作.

It won't work if you generate a Rails 3.1 application, which adds config/initializers/wrap_parameters.rb, and then try to boot it with Rails 3.0.x.

如果要使用Rails 3.1: 您是否正在使用捆绑软件运行，例如bundle exec unicorn_rails或bundle exec rake?

If you want Rails 3.1: Are you running with bundler, e.g. bundle exec unicorn_rails or bundle exec rake?

如果要使用Rails 3.0.x: 通过运行rails new appname以查看需要更改的内容来重新生成应用程序.

If you want Rails 3.0.x: Regenerate the application by running rails new appname to see what needs to change.
