在法布里以sudo的身份执行

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。

我用了sudo(service app start-demo)和sudo(sudo service app start-demo)但是我仍然得到

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

作为终端中的命令行执行它没有问题。

我不确定SADeprecationWarning:是否算作构造失败？

谢谢。

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

任何一个sudo命令都将失败。

这主要与faq中提到的有关，但是如果命令不返回0（unix标准是完全正确的），它将很快失败，除非您告诉它只发出警告。
