fabric自動(dòng)化部署的配置遇到個(gè)問題！希望您能抽空回答！(｀?ω?′)

這是代碼python

#!/usr/bin/env python
# -*- coding: utf-8 -*-

# fabfile.py
import os, re
from datetime import datetime

# 導(dǎo)入Fabric API:
from fabric.api import *


env.use_ssh_config = True
# 服務(wù)器登錄用戶名:
# env.user = 'ubuntu'
# sudo用戶為root:
# env.sudo_user = 'ubuntu'
# 服務(wù)器地址，可以有多個(gè)，依次部署:
env.hosts = ['ubuntu@ec2-18-220-216-89.us-east-2.compute.amazonaws.com']
# env.key_filename = '/cygdrive/c/Users/jiaji/.ssh/jiajixuqqcom.pem'
# env.ssh_config_path = '/cygdrive/c/Users/jiaji/.ssh/config'

# 服務(wù)器MySQL用戶名和口令:
db_user = 'root'
db_password = '6Sb8qzM38'

_TAR_FILE = 'dist-awesome.tar.gz'
_REMOTE_TMP_TAR = '/tmp/%s' % _TAR_FILE
_REMOTE_BASE_DIR = '/srv/awesome'


def touchfile():                         # 隨便創(chuàng)建一個(gè)任務(wù)，用來測(cè)試
    run('touch /tmp/www.txt')

這是ssh的config配置

Host myserver
  HostName ec2-18-220-216-89.us-east-2.compute.amazonaws.com
  Port 22
  User ubuntu
  IdentityFile C:\Users\jiaji\.ssh\jiajixuqqcom.pem

ssh 測(cè)試可通過

但是運(yùn)行fab touchfile無(wú)反應(yīng)

其他一些信息：amazon EC2 服務(wù)器，ssh私密.pem是從服務(wù)器后臺(tái)下載，可ssh連接成功。用了Cygwin64 Terminal來執(zhí)行tab touchfile
