Error: All configured authentication methods failed levels: 'client-authentication' - node.js

Question

I am using node.js ssh2 module.I have installed ssh2 module by executing the command 'npm install ssh2'.However, when I use ssh2 to connect to a remote server, it always output the error:
[Error: All configured authentication methods failed] levels: 'client-authentication'
This is my code
var Client = require('ssh2').Client
var conn = new Client();
var option = {
host: '10.171.65.154',
port: 22,
username: 'root',
password: '123456'
};
conn.on('ready', function(){
console.log('Client :: ready');
conn.sftp(function(err, sftp){
if(err) throw err;
sftp.readdir('home', function(err, list){
if(err) throw err;
console.dir(list);
conn.end();
});
});
}).on('error', function(err){
console.log(err);
}).connect(option);
However, I can not connect successfully.I am sure the username and password are correct and I can connect successfully by SecureCRT.
it always output the error:
[Error: All configured authentication methods failed] levels: 'client-authentication'

Probably, you have to handle keyboard-interactive authentication (which is not the same as password). Try something like this:
connection.on('ready', function(){
console.log("Connected!");
}).on('error', function(err){
console.error(err);
}).on('keyboard-interactive', function (name, descr, lang, prompts, finish) {
// For illustration purposes only! It's not safe to do this!
// You can read it from process.stdin or whatever else...
var password = "your_password_here";
return finish([password]);
// And remember, server may trigger this event multiple times
// and for different purposes (not only auth)
}).connect({
host: "your.host.or.ip",
port: 22,
username: "your_login",
tryKeyboard: true
});
