蟒蛇无法从根执行脚本的权限执行降火狐网页浏览器

Question

我不能从滴特权普通用户一个sudoed Python脚本运行的Firefox。如果我写

$ sudo python
>>> import os
>>> import pwd, grp
>>> uid = pwd.getpwnam('norby')[2]
>>> gid = grp.getgrnam('norby')[2]
>>> os.setegid(gid)
>>> os.seteuid(uid)
>>> import webbrowser
>>> webbrowser.get('firefox').open('www.google.it')
True
>>> # It returns true but doesn't work
>>> from subprocess import Popen,PIPE
>>> p = Popen('firefox www.google.it', shell=True,stdout=PIPE,stderr=PIPE)
>>> # Doesn't execute the command
>>> You shouldn't really run Iceweasel through sudo WITHOUT the -H option.
Continuing as if you used the -H option.
No protocol specified
Error: cannot open display: :0

我认为不是蟒问题，但Firefox / iceweasel / Debian配置问题。也许Firefox的只读UID和不EUID，因为UID是等于0.你怎么看待不执行过程？

这可能是您的环境。更改权限将仍然留在像根用户目录$ HOME指点，这将是无法访问的环境变量。这可能是值得尝试通过启动浏览器之前改变os.environ改变这些变量。还可以有值得检查其他变量。
