Question

我使用ssh2库作为nodejs。

# server.coffee
new ssh2.Server
    privateKey: fs.readFileSync './id_rsa'
    port: 57037
, (client) ->
    console.log 'Client connected'

    client.on 'authentication', (ctx) ->
        ctx.accept()
    .on 'ready', ->
        console.log 'Client authenticated'
        client.on 'session', (accept, reject) ->
            console.log 'session'
            session = accept()
            console.log 'accept'
            console.log session.on
            session.on 'shell', (accept, reject, info) ->
                console.log('Client wants to execute: ' + inspect(info.command));
                stream = accept()
                stream.stderr.write 'Error!'
                stream.write 'Just kidding'
                stream.exit 0
                stream.end()
            session.on 'error', ->
                console.log 'error'

# client.coffee
conn = new Client()
conn.on 'ready', ->
    console.log 'Client :: ready'
    conn.shell (err, stream) ->
        console.log 'shell'
        if err then throw err
        stream.on 'close', ->
            console.log 'Stream :: close'
            conn.end()
        .on 'data', (chunk) ->
            console.log 'STDOUT:', data
        .stderr.on 'data', (chunk) ->
            console.log 'STDERR:', data
        stream.end 'ls -al'
.connect()

当我这样做时，我收到以下错误：

Error: Unable to request a pseudo-terminal

    at doWrite (_stream_writable.js:301:12)
    at writeOrBuffer (_stream_writable.js:288:5)

我该怎么办？

您没有处理pty会话事件。没有事件处理程序时的默认操作是拒绝请求。因此，要允许所有pty个请求，请添加以下内容：

session.on 'pty', (accept, reject, info) ->
    accept()

nodejs的ssh2库：错误：无法请求伪终端
