导轨 - 耙分贝：创建错误

Question

我试着运行耙分贝：创建一个MySQL数据库，但得到的错误

$ rake db:create 
rake aborted! 
undefined method `task' for #<Sharebox::Application:0x0000010085a010> 

伊夫运行--trace并获得信息

这是我的database.yml文件

development: 
    adapter: mysql 
    encoding: utf8 
    reconnect: false 
    database: sharebox_development 
    pool: 5 
    username: root 
    password: 
    host: localhost 

伊夫重新安装红宝石，导轨和MySQL，但仍然得到同样的错误任何帮助，将不胜感激。欢呼声

您应该在您的GemFile中精确定位您的Rake版本。

Rake 0.9刚刚出来，但打破了Rails。

这里的dhh鸣叫：

Rake 0.9,released yesterday, broke Rails (and others). While we wait for a fix, you'll want gem 'rake', '0.8.7' in your Gemfile.

尝试吗？

编辑：另外，如果您真的需要Rake 0.9而不是Rake 0.8.7，请参阅that post。也许这种解决方案会为你工作。
