当工作目录位于UNC路径上而不是映射驱动器时调用subprocess.Popen（）

python

#!/usr/bin/env python
import os
import subprocess

def runMySubProcess(cmdstr, iwd):
    p = subprocess.Popen(cmdstr,
        shell=True,
        cwd=iwd,
        stdout=subprocess.PIPE,
        stderr=subprocess.PIPE)
    (stdout, stderr) = p.communicate()
    if stderr:
        raise IOError, stderr
    return stdout

if __name__ == '__main__':
    print runMySubProcess('python -h', 'C:\')
    print runMySubProcess('python -h', '\\htpc\nas')
