Question

我目前正在运行Rails 4.0.0，ruby 1.9.3p392（2013-02-22修订版39386）[x86_64-darwin10.8.0]，使用Rake 10.1.1

我正在为Rails中的一个类开发应用程序，当我去运行rake数据库迁移时，我收到以下错误消息：

Joses-MacBook-Air:crumblr JRV$ rake db:migrate
rake aborted!
You have already activated rake 10.1.1, but your Gemfile requires rake 10.1.0. Using      bundle exec may solve this.

(See full trace by running task with --trace)

恢复或覆盖此问题以允许迁移的解决方案是什么？

Answer 1

就像它建议的那样，你可以bundle exec rake db:migrate

对于不需要添加前缀的解决方案，请尝试执行bundle update rake

Rails 4.0.0，Gemfile需要rake 10.1.0 for Rake
