我在我的 OpenSUSE 发行版中安装了 meanjs，但是当我运行 npm start 时，我得到了以下结果：
+ Important warning: config.domain is empty. It should be set to the fully qualified domain of the app.

我已经重新安装了两次meanjs，但都没有成功。 Mongo也在运行。顺便说一句：
tasher@linux-hcjz:~/Projects/meanjs_test> node -v
v6.11.1
tasher@linux-hcjz:~/Projects/meanjs_test> npm6 -v
3.10.10
有什么想法吗？

MongoDB 错误是因为您无权在数据库上运行命令。默认情况下，连接字符串 MEAN 使用的是
mongodb://localhost/mean-dev。如果在本地 mongod 上启用了身份验证，则需要更改连接字符串以包含用户名和密码。有关更多信息，请参见此处：docs.mongodb.com/manual/tutorial/enable-authentication 另一个选项是在本地 mongod 上禁用身份验证（仅当您仅使用本地数据库进行开发时才应该这样做）。
