我有一个Python脚本,它作为Windows服务运行.该脚本分叉另一个进程:

with subprocess.Popen( args=[self.exec_path], stdout=subprocess.PIPE, stderr=subprocess.STDOUT) as proc:

这会导致以下错误:

OSError: [WinError 6] The handle is invalid
   File "C:\Program Files (x86)\Python35-32\lib\subprocess.py", line 911, in __init__
   File "C:\Program Files (x86)\Python35-32\lib\subprocess.py", line 1117, in _get_handles
