python - 在 fabric 中作为 sudo 执行

Question

我有一个命令 service app start-demo 要求我在命令行中键入 sudo service app start-demo。

我使用了 sudo(service app start-demo) 和 sudo(sudo service app start-demo) 但我还是得到了

警告:sudo() 在执行“sudo service app start-demo”时遇到错误(返回代码 1)

我在终端中将其作为命令行执行没有问题。

我不确定 SADeprecationWarning: 是否算作构造失败？

谢谢。

user@box:/var/lib/app$ fab kickstart
You are installing prereqs..........
### Install Prereqs for Populate ###
No hosts found. Please specify (single) host string for connection: localhost
[localhost] Login password: 

### I am starting demo ###
[localhost] sudo: sudo service app start-demo
[localhost] out: Starting demo

Fatal error: sudo() encountered an error (return code 1) while executing 'sudo service app start-demo'

Aborting.
Disconnecting from localhost... done.

代码

def pserve():
    print '### I am starting demo ###'
    #with settings(warn_only=True):
    sudo('sudo service app start-demo')
    #sudo('service app start-demo')

sudo 命令都会失败。

这与 faq 中的提及密切相关，而且如果命令不返回 0(所有好的 unix 标准)，除非您告诉它仅发出警告，否则它将快速失败。
