Question

我有一小段代码（大型程序的一部分）只检查驱动器号和CDROM的状态

import wmi

print '--checkCDContent--'
c=wmi.WMI()

cdrom = c.Win32_CDROMDrive()
status = cdrom[0].MediaLoaded
drive = cdrom[0].Drive

print drive, status

作为更大程序的一部分，我必须使用cxFreeze编译代码来创建一个exe。为了测试我的问题，我单独使用上面的代码来复制它。

当我从硬盘驱动器运行.exe时，它正确运行。当我从CD本身运行它（我的最终目标）时，我收到以下错误

X:\>CDrun.exe
--checkCDContent--
Traceback (most recent call last):

pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'SWbemServicesEx', u'Not found ', None, 0, -2147217406), None)

我怀疑是它有这个错误，因为代码实际上是从CD运行，同时它试图获得CD的状态更新。任何人都可以验证这一点并建议解决方案吗？

python：pywintypes.com_error从CDRom运行而不是HD
