尝试运行bundle update，但在控制台中出现以下错误。

Bundler could not find compatible versions for gem "rack":

我想继续升级到Rails 5.0。我可以找到解决所有错误的方向。

  railties (>= 3.0)

sass-rails was resolved to 5.0.6, which depends on
  railties (< 6, >= 4.0.0)

删除您的Gemfile.lock文件，然后尝试再次更新。

将Rails应用程序从4.0升级到5.0时，Bundle Update无法找到依赖项
