Question

与ftp服务器进行交互时，我尝试使用Promise方法。我正在使用节点包'promise-ftp'v1.3.5。

我的代码如下：

const appFeedBuffer = Buffer.from('somedatastring', 'utf8');
var Client = require('promise-ftp');
var ftpClient = new Client();

ftpClient.connect({ host: 'myHost', user: 'me', password: 'mypassword' })
    .then(() => {
        return ftpClient.mkdir('newDir')
    }).then(() => {
        return ftpClient.put(appFeedBuffer, 'fileName')
    }).then(()=> {
        return ftpClient.rmdir('oldDir')
    }).then(() => {
        return ftpClient.rename('newDir', 'oldDir')
    }).then(() => {
        return ftpClient.end();
    }).catch(err => {
        console.log("something went wrong: " + err);
        res.status(500).send('SERVER ERROR');
});

问题是put命令-我收到错误消息'未知的命令'，该错误似乎来自@icetee/ftp库，promise-ftp是依赖库的。 put无疑是promise-ftp库中的有效命令！

堆栈：

我找不到其他人遇到此问题。我在做什么错了？
