我按照OpenProject 安装。我的操作系统是 Window-7。当我执行bundle exec rake db:create:all时，我得到如下
C:\Sites\openproject>bundle exec rake db:create:all
DL is deprecated, please use Fiddle
require 'rails/all'... 2.277s
Bundler.require... 5.071s
*** WARNING: You must use ANSICON 1.31 or higher (https://github.com/adoxa/ansic

LoadError: Please install the mysql2 adapter: `gem install activerecord-mysql2-a
dapter` (cannot load such file -- mysql2/2.0/mysql2)

(See full trace by running task with --trace)
这就是为什么，我gem install activerecord-mysql2-adapter按照控制台所说的那样执行。现在，它可以如下所示。
C:\Sites\openproject>gem install activerecord-mysql2-adapter
Successfully installed activerecord-mysql2-adapter-0.0.3
Parsing documentation for activerecord-mysql2-adapter-0.0.3
1 gem installed
我bundle exec rake db:create:all 再次执行，我再次收到错误
C:\Sites\openproject>bundle exec rake db:create:all
