我以为我升级了Rails版本，但是没有用

Question

I have an app running on Rails 2.3.3.

I edited my environment.rb

RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION

Then performed rake rails:update

In my console:

>> Rails.version
    2.3.3

What am I forgetting to do?

Answer 1

Try manually installing rails 2.3.8

gem install rails -v=2.3.8

In some env's this works better (I found this to be the case when using rvm).

Answer 2

尝试执行“捆绑更新”，这将更新锁定文件。

Answer 3

You probably just froze your rails gems into your project. This will force the application to load the frozen version. Just remove vendor/rails and you should be all set. Then you can freeze 2.3.8 if you need to. Is there a reason you aren't just going to 2.3.11?
