Bundler 找不到 gem "activerecord" 的兼容版本：

Question

当我尝试升级我的

• Ruby 1.9.3 到 Ruby 2.2.2
• Rails 3.2.14 到 Rails 4.2.4

运行bundle install 时出现此错误：

请帮忙。

我遇到了几乎相同的错误，但我也有一些信息，因为我需要更新 bundler 和 rake，所以常规的更新方式会重现相同的错误。

我的解决方案是在安装行添加“--source http://rubygems.org”： 喜欢： gem install rake -v '11.3.0' --source http://rubygems.org gem install bundler --pre --source http://rubygems.org
