RailsBump，一个在线小工具

[veryitman]

RailsBump lets you check your Ruby gems for compatibility with all major Rails versions. This is useful if you're planning to upgrade a Rails app to the next major version. You can either check an individual gem or a "lockfile" generated by Bundler (Gemfile.lock) containing all the gems of your Ruby project.
Read more about how RailsBump works and the history of this project on GitHub and please open an issue if you encounter any problems.

 

如果你要是升级工程的 Rails 版本，可以使用这个工具检查一下你的 gem 兼容性。
