ruby-on-rails – rake db：migrate失败并显示错误：“rake aborted！未定义的方法`弃用’为#“

花了一些时间没有在轨道上编程,现在我“回来了”事情出了问题.
我安装了 ruby 1.9.2-p0并坚持使用rails 3.0.1.Updated所有gems和bundle运行成功.修复了一个新的rails应用程序并创建了一个迁移但是在运行时

rake db:migrate

我明白了：

rake aborted!

我确实迷失在这里,所以任何小费都会受到高度赞赏

编辑：

跑完之后

bundle exec rake

我明白了：

Run "rake db:migrate" to update your database then try again.

解决方法

如果您使用的是rails 3.0.1,可以在gemfile中尝试：

gem 'rake','0.8.7'

或者尝试在gemfile中迁移到3.0.9更改.

之后运行：

bundle update
