Could not find "config/databases/mysql.yml" in any of your source paths. Your current source paths are: /home/ronggothelast/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/railties-5.2.1/lib/rails/generators/rails/app/templates

您似乎已经使用删除系统上所有 MySQL 文件的命令从模板文件夹中删除了 mysql.yml.tt。
要解决这个问题:1)在templates/config/databases/目录下创建mysql.yml.tt文件

$ touch ~/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/railties-5.2.1/lib/rails/generators/rails/app/templates/config/databases/mysql.yml.tt

2) 粘贴 original file from rails github 中的基本代码使用 vim 或从源文件打开文件并粘贴所有代码。

$ vim ~/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/railties-5.2.1/lib/rails/generators/rails/app/templates/config/databases/mysql.yml.tt

现在您可以使用 rails new app-name -d mysql 重新制作项目
