我的经验有限，但我相信既然你是“sudo”安装py2.6，你就需要是“sudo”来运行它，或者至少是在正确的组中（在Ubuntu上是“wheel”还是类似的东西？） 我想一个简单的测试是，改变这个：
_sudo('apt-get install python2.6')
version = run("python2.6 -V").split()[1]
_sudo('apt-get install python2.6')
version = _sudo("python2.6 -V").split()[1]
&看看是否仍然提示您输入密码。请添加整个脚本，或者至少在包含所有定义的地方。我刚刚添加了完整脚本，我更新了现有的postAs Auston说。注意run（）和sudo（）是相同的。如果希望另一端出现提示，请使用sudo（）。（因此相反，如果我在sudoers中将用户的命令配置为NOPASSWD，那么当我运行sudo命令时，我不会使用sudo（），而是使用run（'sudo blahcommand'））
