在您的任何源中都找不到"config/databases/mysql.yml" 路径。您当前的源路径为：/home/ronggothelast/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/railties-5.2.1/lib/rails/generators/rails/app/templates
您似乎已使用命令从模板文件夹中删除了 mysql.yml.tt，以删除系统上的所有MySQL文件。
要修复它： 1( 在目录模板/配置/数据库/中创建 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( 使用 vim 从 rails github 粘贴原始文件中的基本代码，或者从其源代码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
