Rails 4 binstubs错误

Question

我在玩 bundler 和 binstubs 以及“rake rails:update:bin”，下次我尝试运行 rails 时遇到了这个异常：

`inherited': undefined method `application' for Rails:Module (NoMethodError)

即使对于我创建并尝试运行的新项目，也会出现相同的异常。

这是全文：

Answer 1

好吧，在发布后几分钟我尝试了：

gem uninstall railties

然后又

bundle install

它解决了这个问题。不过，我仍然不知道一开始会发生什么。
