ruby-on-rails - Determine which gems are not being used in Rails App

Question

Hey fellow stackerenos!

I'm working on a massive Rails 2.3.18 app with 90 gems in the Gemfile and 60 vendor plugins.

What's the best systematic way to determine which gems/plugins I don't need anymore?

Answer 1

移除一个 gem，运行你的测试套件。如果它失败了，你仍然需要那个宝石。如果没有，您可能不再需要它。我建议您在删除它之前进行进一步调查，也许您尚未测试的某些代码需要它。
