如何在rails3.2和rails4.0之间切换？

Question

I have installed rails3.2.13 and rails4.0 on my pc.Browsercms needs rails3.2 and don't support rails4.0,so when I run browsercms, I need to swicth from rails4.0(general use) to rails3.2.The way is:

$rvm use 1.9.3
$gem install rails -v 3.2.13
$rvm gemset create rails3.2
$rvm use 1.9.3@rails3.2
$rvm info

It can switch from rails4.0 to rails3.2.but after I want to be back to rails4.0,but can't complete.So how can I switch from rails3.2 to rails4.0?

Answer 1

您可以在应用程序的Gemfile中放置gem'rails gem 'rails', '3.2.13' 。
