回滚轨道版

Question

我目前已经安装了Rails 3.2.13（gem install rails -v 3.2.13）。但由于某些原因，我需要回滚到版本3.2.13。我该怎么做？ 现在：

> rails -v    
You have requested:

  rails = 3.2.13

The bundle currently has rails locked at 3.2.12.
Try running `bundle update rails`
Run `bundle install` to install missing gems.

Answer 1

在您的Gemfile中，查找gem 'rails'行并将其更改为

gem 'rails', '3.2.12'

然后运行bundle install
