獲取錯誤： invalid schema, expected mongodb ，同時使用nodeman啟動服務器

C:\Users\NDLM\Documents\workspace\angular-drywall>nodemon app.js
[nodemon] 1.12.0
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*

    throw new Error('invalid schema, expected mongodb');
    ^

准確地看一下mongodb url_parser.js文件第 20 行中的代碼片段。

if(result.protocol != 'mongodb:') {
    throw new Error('invalid schema, expected mongodb');
}

這告訴我，URI連接字符串未使用所需mongodb:// prototcol更改您的URI的連接字符串。 你的服務器應該停止崩潰。

包示例： https : //www.npmjs.com/package/mongodb#connecting-to-mongodb
