我也尝试了网络上的其他一些东西： -gem install mysql2从命令行运行得到与上面相同的消息。- 运行gem 'mysql2'给我这个错误：ERROR: While executing gem ... (Gem::CommandLineError) Unknown command mysql2即使我有它我的 Gemfile：http ://d.pr/n/jc3i
- 我已经尝试添加rvm install libmysql-ruby希望能解决它.. 不..
我应该提到这是我第一次真正涉足 RoR，所以很可能我是问题所在......我已经查看了 StackOverflow 并且在那里也没有真正的运气。任何帮助将不胜感激。
