Rake Abort 错误，除了撞墙之外没有任何答案。如有必要，请重复

Question

我是一个勇敢的小程序员。我五周前开始对 Rails 进行编程，并且在整个过程中我都陷入了同样的错误。事情是这样的。我安装了mysql应用程序，有最新的rails（2.3.5），ruby（1.8.6）和mysql（5.1.40）。

我多次创建了一个非常漂亮的数据库和表格，其中包含 Rails 中的内容，同样的事情只是为了确保。它就在那里。有用。

然后我进入我的database.yml并确保我的登录名/密码root访问数据库是mysql，一切都很好。绿灯。

然后我做了一个 rake db:migrate..

然后我得到了这个

    rake aborted!
    undefined method `generate_best_match=' for ActionController::Routing:Module

说真的，没有交易..

五周了..

一个家伙要做什么？谢谢！

Answer 1

这相关吗？ 回复：部署错误：未定义方法“generate_best_match=”

Answer 2

注释掉以下行：

ActionController::Routing.generate_best_match = false

尝试在 config/initializers/new_rails_defaults.rb 中

您会丢失 2.3.4 中引入的一些路由更改，但至少它可能会让您的应用程序运行。

Answer 3

这个错误是由于没有使用正确的mySQL版本引起的。就我而言，是 32 位。一旦我安装了 32 位 mySQL，并使用了 32 位 gem，这一切就完美了。
