Question

我正在运行Python3并且一直在尝试运行sshls.py脚本但总是失败：

AttributeError：'module'对象没有属性'spawn“

我试过跑：

python3 sshls.py

我甚至修改了脚本以设置env或python脚本但仍然失败：

#!/usr/bin/python3

OR

#!/usr/bin/env python3

我尝试使用python2.7并仍然得到相同的错误。

脚本内容：

from __future__ import print_function

from __future__ import absolute_import

import pexpect
import getpass, os, traceback
def ssh_command (user, host, password, command):
     ssh_newkey = 'Are you sure you want to continue connecting'
     child = pexpect.spawn('ssh -l %s %s %s'%(user, host, command))
     i = child.expect([pexpect.TIMEOUT, ssh_newkey, 'password: '])
     if i == 0: # Timeout
         print('ERROR!')
         print('SSH could not login. Here is what SSH said:')
         print(child.before, child.after)
         return None
     if i == 1: # SSH does not have the public key. Just accept it.
         child.sendline ('yes')
         child.expect ('password: ')
         i = child.expect([pexpect.TIMEOUT, 'password: '])
         if i == 0: # Timeout
             print('ERROR!')
             print('SSH could not login. Here is what SSH said:')
             print(child.before, child.after)
             return None
     child.sendline(password)
     return child

def main ():
     host = "www.example.com"
     user = "root"
     password = "password"
     child = ssh_command (user, host, password, '/bin/ls -l')
     child.expect(pexpect.EOF)
     print(child.before)

if __name__ == '__main__':
     try:
         main()
     except Exception as e:
         print(str(e))
         traceback.print_exc()
         os._exit(1)

Answer 1

好的，最后通过将pexpect.py脚本复制到我的脚本所在的目录中来实现它。奇怪的是，通过在IDLE中独立执行我的代码它可以工作，但不能通过python，除非pexpect.py与你的脚本在同一个目录中。

请参阅：http://pexpect.readthedocs.io/en/stable/overview.html#windows

要求此版本的Pexpect需要Python 3.3或更高版本，或Python 2.7。

从4.0版开始，Pexpect可用于Windows和POSIX系统。但是，pexpect.spawn和pexpect.run（）仅适用于POSIX，其中pty模块存在于标准库中。有关详细信息，请参阅Pexpect on Windows。

pexpect - 无法运行示例，不断获取AttributeError：'module'对象没有属性'spawn'

AttributeError：'module'对象没有属性'spawn“
