当我运行 bundle exec rake db:initial_setup 时，出现错误:
rake aborted! undefined method `searcher' for Gem:Module.
我该如何解决这个问题？
这里是 bundle exec rake db:initial_setup --trace 的输出
rake aborted!
undefined method `searcher' for Gem:Module

最佳答案
这是因为 Gem.searcher 已被弃用，看来您最近更新了 ruby gems。 使用命令检查你的versiob
$ gem -v
你可以使用命令回到任何旧版本
$ rvm rubygems 1.8.24
关于ruby - Gem :Module 的未定义方法 `searcher'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15651371/
