Error of using share extension

[uncompleted]

The scripts I have is only two imports:
import os import appex

when a photo is shared by selecting 'Run Pythonista Script' -> personalized scripts, it shows below error message:

Traceback (most recent call last): File "/private/var/mobile/Containers/Shared/ AppGroup/0659F643-BA52-4098-B9D4-B225AC75C2C7/ Pythonista3/Documents/Examples/Extension/Text Statistics.py", line 3, in <module > import appex File "/var/containers/Bundle/Application/ 1B6CFCED-8420-4F81-AB4D-E29379C12097/ Pythonista3.app/Frameworks/Py3Kit.framework/ pylib/site-packages/pythonista/appex.py", line 5, in ‹module> import ui File "/var/containers/Bundle/Application/ 1B6CFCED-8420-4F81-AB4D-E29379C12097/ Pythonista3.app/Frameworks/Py3Kit.framework/ pylib/site-packages/pythonista/ui.py", line 4, in ‹module> import re File "/var/containers/Bundle/Application/ 1B6CFCED-8420-4F81-AB4D-E29379C12097/| Pythonista3.app/Frameworks/Py3Kit.framework/ pylib/re.py" ', line 146, in ‹module› class RegexFlag (enum.IntFlag): AttributeError: module 'enum' has no attribute 'IntFlag'

Anyone knows how to solve this issue?

I have googled the error message, and found this reference:

It looks like you may have the wrong "enum" module imported. May be you have packages installed in "site-packages (user)" that override the enum module that comes with Pythonista.

To pinpoint the problem, you could enter the following in the Pythonista console:

>>> import enum
>>> print(enum.__file__)
/var/containers/Bundle/Application/508A7160-E8FF-41BE-BDB6-96FAD245BE04/Pythonista3.app/Frameworks/Py3Kit.framework/pylib/enum.py

>>> enum.IntFlag
<enum 'IntFlag'>
