当我在 application.rb 中有以下行时，我的 rails 应用程序无法加载：

Bundler.require(:default, Rails.env)

我收到以下错误：

看起来好像是在抱怨传入的参数——这很奇怪，因为这是预先准备好的 Rails 东西。请注意，Bundler.require 是它所抱怨的 application.rb:5。

我在 Rails 4，Ruby 2.0.0

【解决方案1】：

看起来您正在使用的 rollify gem（所以它不是干净的 rails 项目：P）在 rails 4.x 系列中存在一些问题。看看这个：https://github.com/EppO/rolify/pull/218 有一个叉子已经解决了这个问题。
