Mysql Service Recipe抛出未定义的方法错误

Question

我尝试使用主厨mysql recipe，但我一直收到错误undefined method '[]' for nil:NilClass。

mysql.rb

mysql_service 'mysql' do
  port '3306'
  version '5.7.10'
  initial_root_password 'SuperSecretPassword'
  action [:create, :start]
end

mysql_config 'foo' do
  source 'wp-config.php.erb'
  notifies :restart, 'mysql_service[mysql]'
  action :create
end

错误日志

该方法涉及查找当前平台的包名称等。可能意味着你正在尝试使用OS /发行版，食谱不支持。
