ruby-on-rails - 由于 bundler 版本冲突，无法激活Rails 3.0.1

Question

所以我跑:

$ gem install rails --version 3.0.1

Successfully installed rails-3.0.1
1 gem installed
Installing ri documentation for rails-3.0.1...
Installing RDoc documentation for rails-3.0.1...

然后我得到错误:

$ rails -v

您可能需要更新到 bundle 软件1.1.4。
gem update bundler
应该做到的。
