【问题描述】：
我正在尝试在 Windows 上的 Rails 上运行一个项目。我安装了 mysql --version 5.7.12。
我运行了bundle install，一切都安装正确。
但是，在运行rake db:structure:load --trace 之后，我收到了以下错误消息：
DL is deprecated, please use Fiddle
For a better pry experience, please use ansicon: http://adoxa.3eeweb.com/ansicon/
** Invoke db:structure:load (first_time)
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:structure:load
rake aborted!
failed to execute:
mysqlPlease check the output above for any errors and make sure that `mysql` is installed in your PATH and has proper permissions.
