百度了一下，都是直接刪除一個臨時文件夾，重新運行后便正常了。

1. 我在用python處理一個excdl文件時，遇到報錯如下：
Traceback (most recent call last):
File "C:/pythonProject/流量短信詳單時間格式_正式腳本.py", line 320, in <module>
main()
File "C:/pythonProject/流量短信詳單時間格式_正式腳本.py", line 308, in main
cuc_data_process()
File "C:/pythonProject/流量短信詳單時間格式_正式腳本.py", line 170, in cuc_data_process
fileName = xls2xlsx(fileName)
File "C:/pythonProject/流量短信詳單時間格式_正式腳本.py", line 16, in xls2xlsx
excel = win32.gencache.EnsureDispatch('Excel.Application')
File "C:\Python_3.6.8\lib\site-packages\win32com\client\gencache.py", line 531, in EnsureDispatch
mod = EnsureModule(tla[0], tla[1], tla[3], tla[4], bForDemand=bForDemand)

AddModuleToCache(typelibCLSID, lcid, major, minor)

dict = mod.CLSIDToClassMap
AttributeError: module 'win32com.gen_py.00020813-0000-0000-C000-000000000046x0x1x9' has no attribute 'CLSIDToClassMap'
Process finished with exit code 1
2.解決方法：
運行下面 4行代碼，找到報錯的臨時文件夾所在路徑，將其刪除
$ python
Python 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 24 2018, 00:16:47) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from win32com.client.gencache import EnsureDispatch
>>> import sys
>>> xl = EnsureDispatch("Word.Application")
>>> print(sys.modules[xl.__module__].__file__)
C:\Users\hp\AppData\Local\Temp\gen_py\3.6\00020905-0000-0000-C000-000000000046x0x1x9\_Application.p
>>>
3. 再次運行python腳本處理excel，可以執行完畢，會發現剛才刪除的臨時文件夾又出現了，不用管它。
