Ruby on rails rake在使用gem'时中止；mysql2''&书信电报；0.3'；

嗨，我的档案里有这个

gem 'rails', '3.0.5'

gem 'mysql2', '< 0.3'

现在我已经运行了bundle安装并获得了这个版本的mysql2-0.2.24。 我什么时候做

rake数据库：创建

这给了我错误

现在请指导如何解决这个问题。提前谢谢。

试试跑步

bundle exec rake db:create

试试这个

gem 'rake', '0.9.2.2'

在Gemfile中，然后运行rake作为

bundle exec rake db:migrate

---

gem'rake'，'10.1.0'将此添加到您的gem文件中，然后捆绑安装仍然是它的给定错误安装了多少个rake版本？通过使用'gem list rake'，只有一个rake-10.1.0您运行过该命令吗？转到您的Rakefile并在第7行设置rdoc/task而不是rake/rdoctask，或者完全删除该行。

bundle exec rake db:migrate
