无法在NodeJS应用程序中的Heroku上添加npm模块

Question

我在Heroku上托管了一个NodeJS应用程序，它重命名了sFTP服务器上的文件。请在下面找到我的app.js代码。如果我删除ssh2-sftp-client npm模块，一切工作正常。但是这样我就不能进行sFTP连接了。我对Heroku和NodeJS都是新手。你能帮我解决这个问题吗。在本地，一切都是工作文件。我对如何将npm ssh2-sftp-client添加到Heroku以正确执行nodeJS代码感到困惑。

    let Client = require('ssh2-sftp-client');
let sftp = new Client();
sftp.connect({
  host: 'host',
  port: 'port',
  username: 'user',
  password: 'password'
}).then(() => {
     return sftp.rename('/After30/Sunil.txt','/After30/Sunil.csv')

}).then(() => {
  console.log('Closing SFTP');
   return sftp.end();

}).catch(err => {
  console.log(err, 'catch error');
});

请查找package.json文件代码，

在package.json中更改了node js引擎版本后开始工作(Put最新版本)
