Question

使用命令 rake rails:upgrade 将我的应用程序从 rails 3.1.3 升级到 rails 3.2.2 之后 输入 localhost:3000 时出现以下错误

Answer 1

问题是您使用的是过时版本的 OmniAuth (0.3.2)。升级到版本 1.x 来解决这个问题。见：https://github.com/intridea/omniauth

请注意，从 0.3.2 到 1.x 有几个重大更改，因此请仔细阅读升级说明：https://github.com/intridea/omniauth/wiki/Upgrading-to-1.0

更新：作为此升级过程的一部分，您应该从 Gemfile 中删除 oa-oauth 引用。

更新 2：我关于仔细阅读升级说明的警告并没有随意抛出：这不是一个完全微不足道的升级，必须小心才能使其正常工作
