Question

我的代码：

var ttn = require("ttn")  
var appID = "***"  
var accessKey = "ttn-account-********************"  
ttn.data(appID, accessKey).then(function (client) {  
    client.on("uplink", function (devID, payload) {  
        console.log("Received uplink from >>>", devID)  
        console.log("payload >>> ", payload);  
    })  
}).catch(function (error) {  
    console.error("Error >>>", error)   
    process.exit(1)  
})

运行此文件时，出现以下错误：

TypeError: The super constructor to "inherits" must have a prototype

同一代码以前在Windows中工作。我刚刚尝试在ubuntu 18.04中运行此代码。现在，我收到此错误。我不确定该错误的来源。因此，我尝试重新安装npm软件包。它不起作用。请帮助我解决此问题。预先感谢。

使用ttn的mqtt-TypeError：“继承”的超级构造函数必须具有原型
