Question

我试图创建一个python可执行文件，它将运行多个wmic调用来检查可移植可执行文件的版本。

以下代码在命令提示符下工作，因此我尝试从python

运行相同的行

wmic datafile where name="C:\\Program Files\\Internet Explorer\\iexplore.exe" get Version /value

Python代码：

import subprocess

spath = r'C:\Program Files\Internet Explorer\iexplore.exe'
cargs = ["wmic","datafile","where", r'name="{0}"'.format(spath), "get", "Version", "/value"]

process = subprocess.check_output(cargs)

我收到以下错误

---------------------------------------------------------------------------
CalledProcessError                        Traceback (most recent call last)

    709     return CompletedProcess(process.args, retcode, stdout, stderr)
    710 

CalledProcessError: Command '['wmic', 'datafile', 'where', 'name="C:\\Program Files\\Internet Explorer\\iexplore.exe"', 'get', 'Version', '/value']' returned non-zero exit status 2147749911

错误消息末尾的命令对我来说是正确的。我哪里错了？

python中的wmic调用返回无效的查询错误
