我正在尝试按照此过程在 Ubuntu 12.04 上安装 Redmine 。
当我尝试使用命令初始化 Redmine 时RAILS_ENV=production rake db:migrate,我收到一条错误消息:please install MySQL adapter.... Can't activate mysql(~> 2.8.1) , already activated MySQL-2.9.1'....
RAILS_ENV=production rake db:migrate
please install MySQL adapter.... Can't activate mysql(~> 2.8.1) , already activated MySQL-2.9.1'...
