Question

我试图运行rake db：为mysql数据库创建但得到错误

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

我运行--trace并获取信息

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

我重新安装了ruby，rails和mysql但仍然得到相同的错误任何帮助将不胜感激。干杯

你应该在你的GemFile中准确你的rake版本。

Rake 0.9刚刚离开但是打破了Rails。

这是dhh的推文：

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.

试试吗？

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。也许这种修复对你有用。
