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，请查看该post 。 也许这种修复对你有用。
