重启后wmi暂时无法使用

标签: python wmi pywin32

登录时我遇到了WMI可用性问题。

重新启动后,我打开cmd并使用python解释器:

>>> import wmi
>>> c = wmi.WMI()
>>> c.Win32_OperatingSystem()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\wmi.py", line 1147, in __getattr__
    return getattr (self._namespace, attribute)
  File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 516, in
__getattr__
    raise AttributeError("%s.%s" % (self._username_, attr))
AttributeError: winmgmts:.Win32_OperatingSystem
>>>

5分钟后,我打开另一个 cmd和python解释器:

Python 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win
32
Type "help", "copyright", "credits" or "license" for more information.
>>> import wmi
>>> c = wmi.WMI()
>>> c.Win32_OperatingSystem()
[<_wmi_object: \\W520-ALEX-WIN7\root\cimv2:Win32_OperatingSystem=@>]
>>>

注意:即使5分钟后,第一个cmd仍然会继续说 AttributeError

注意2:如果我注销并登录wmi可用,那么它会以某种方式重启

使用进程资源管理器我检查环境变量并且它们对于两个cmds都是相同的

那可能是什么? 请帮忙。

更新:显然问题是连接到wbem服务:

>>> import win32com.client
>>> win32com.client.Dispatch('WbemScripting.SWbemLocator')
<COMObject WbemScripting.SWbemLocator>
>>> wmi_service= win32com.client.Dispatch('WbemScripting.SWbemLocator')
>>> wbem_service =  wmi_service.ConnectServer('.','root/cimv2')
>>> wbem_service
<COMObject <unknown>>
>>> items = wbem_service.ExecQuery('Select * from Win32_OperatingSystem')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<COMObject <unknown>>", line 3, in ExecQuery
  File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 282, in
_ApplyTypes_
    result = self._oleobj_.InvokeTypes(*(dispid, LCID, wFlags, retType, argTypes
) + args)
pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'SWbemServicesEx
', u'Generic failure ', None, 0, -2147217407), None)
>>>

注3:wmic os始终有效。

注意4:重新安装pywin32软件包没有帮助。也没有重新注册/重新编译WMI组件和重置WMI数据库(按照建议here

注意5:我的4台其他笔记本电脑没有此问题。
