ruby -v:ruby 1.9.3p194(2012-04-20修订版35410)[x86_64-linux]
rails -v:Rails 3.2.3
gem -v:1.8.24
michele@michele:~/rails/my_app$ gem install mysql2
Building native extensions. This could take a while...
Successfully installed mysql2-0.3.11
1 gem installed
Installing ri documentation for mysql2-0.3.11...
Installing RDoc documentation for mysql2-0.3.11...
在此之后我编辑了database.yml并运行:
rake db:create
它返回:
rake aborted!

所以,当我最终尝试安装它时,我收到错误:
michele@michele:~/rails/my_app$ gem install activerecord-mysql2-adapter
ERROR: Could not find a valid gem 'activerecord-mysql2-adapter' (>= 0) in …
