我在我的OpenSUSE發行版安裝meanjs，但是當我運行npm start，這裏就是我得到：MEAN：未處理拒絕MongoError：沒有被授權就意味着-dev的執行命令

我有重新安裝meanjs兩次，但徒勞無功。 Mongo也在運行。順便說一下：
[email protected]:~/Projects/meanjs_test> node -v
v6.11.1
[email protected]:~/Projects/meanjs_test> npm6 -v
3.10.10
有什麼想法？
MongoDB的錯誤是因爲你沒有授權的數據庫上運行命令替換路徑path_for_package。默認情況下，MEAN使用的連接字符串是'mongodb：// localhost/mean-dev'。如果在本地mongod上啓用了auth，則需要更改連接字符串以包含用戶名和密碼。請參閱此處以獲取更多信息：https://docs.mongodb.com/manual/tutorial/enable-authentication/ 另一種方法是禁用本地mongod上的身份驗證（只應在您僅使用本地數據庫開發）。 – tfogo
