python运行报pywintypes.com_error: (-2147352567, '发生意外。哪位大神知道？求解惑

初学python，完全是照着别人的写了一下，结果运行就报错，网上也找了下，确实不知道怎么解决。

import time
import os, sys, platform
import _winapi
class cpuMonitor:
def __init__(self):
return
def getCpu(self):
sysName = platform.system()
if sysName == 'Windows':
return self.getWinCpu()
else:
return self.getLinuxCpu()
return
def getWinCpu(self):
import win32com.client
com = win32com.client.Dispatch("WbemScripting.SWbemRefresher")
obj = win32com.client.GetObject("winmgmts:\\root\cimv2")

processorItems = com.AddEnum(obj, "Win32_PerfFormattedData_PerfOS_Processor").objectSet

while(1):
com.Refresh()
for item in processorItems:
if item.Name == '_Total':
return item.PercentProcessorTime
break
def _read_cpu_usage(self):
try:
fd = open("/proc/stat",'r')
lines = fd.readlines()
finally:
if fd:
fd.close()
for line in lines:
l = line.split()
if len(l) < 5:
continue
if l[0].startswith('cpu'):
return l
return []
def getLinuxCpu(self):
cpustr = self._read_cpu_usage()
if not cpustr:
return 0
usni1 = int(cpustr[1])+int(cpustr[2])+int(cpustr[3])+int(cpustr[5])+int(cpustr[6])+int(cpustr[7])+int(cpustr[4])
usn1 = int(cpustr[1])+int(cpustr[2])+int(cpustr[3])

usni2 = int(cpustr[1])+int(cpustr[2])+int(cpustr[3])+int(cpustr[5])+int(cpustr[6])+int(cpustr[7])+int(cpustr[4])
usn2 = int(cpustr[1])+int(cpustr[2])+int(cpustr[3])
cpuper = (usn2-usn1)/(usni2-usni1)
return 100*cpuper
def main():
aaa = cpuMonitor()
# result = aaa.getCpu()
print(aaa.getCpu())

if __name__ == '__main__':
main()

错误信息：

Answer 1

SWbemRefresher，这个class需要确认是否存在。你可以用OLEViewer查看。

Answer 2

你的程序我运行成功，能不能私信交流。

追问
