节点ssh2: TypeError：<Object>不是构造函数

Question

我有node v14.17.0和ssh2 1.1.0 https://www.npmjs.com/package/ssh2

我尝试使用下面的代码进行连接，但它在TypeError: NodeSSH is not a constructor上崩溃

我也试过

var NodeSSH= require('ssh2');

var c = new NodeSSH();

和

var NodeSSH= require('ssh2').Client;

和

const {NodeSSH} = require('ssh2');
const c = new NodeSSH();

c.on('keyboard-interactive', function(name, instructions, instructionsLang, prompts, finish) {
    console.log('Connection :: keyboard-interactive');
    finish(['pswd']);
    }).on('end', function() {
        console.log('Connection :: end');
        console.log(callback());
    }).on('error', function(error) {
        console.log(error);
    }).connect({
        host: 'XX.XX.XXX.XXX',
        username: 'usr',
        port: "22",
        tryKeyboard: true,
        debug: console.log
    });

我似乎找不出是什么原因造成的。

我认为你应该这样做，你获取实例的方式是不正确的。

const { Client } = require('ssh2'); // it exports Client not NodeSSH

const conn = new Client();

conn.on('keyboard-interactive', function(name, instructions, instructionsLang, prompts, finish) {
    console.log('Connection :: keyboard-interactive');
    finish(['pswd']);
    }).on('end', function() {
        console.log('Connection :: end');
        console.log(callback());
    }).on('error', function(error) {
        console.log(error);
    }).connect({
        host: 'XX.XX.XXX.XXX',
        username: 'usr',
        port: "22",
        tryKeyboard: true,
        debug: console.log
    });

你应该检查文档如何使用它，尽管你已经在问题中分享了它。我建议你再看一遍。
