请教各位 gem 问题
Please install the mysql adapter: `gem install activerecord-mysql-adapter` (can't activate mysql (~> 2.8.1, runtime), already activated mysql-2.9.0. Make sure all dependencies are added to Gemfile.)

我卸载2.9.0 后
gem install -v=2.8.1 mysql
gem uninstall -v=2.9.0
执行又出现这个错误,晕了
# rake db:migrate RAILS_ENV=production
Could not find mysql-2.9.0 in any of the sources
Run `bundle install` to install missing gems.
