I got a problem when using python3.8 to run flask

[somewheve]

I try to use the virtual environment based on python 3.8 to running
a flask program in Arch Linux.

But I got an error

TypeError: required field "type_ignores" missing from Module'

So I search it by google and find a way to solve it.

and I change the code to the next version and it works

werkzeug/routing.py line:950-952

module = ast.fix_missing_locations(ast.Module([func_ast],[]))
code = compile(module, "<werkzeug routing>", "exec")
return self._get_func_code(code, func_ast.name)

Hope for your reply and fix

Can you add a code sample to reproduce as well as a Pipenv.lock file or the results of a pip freeze for me to reproduce the issue? I have been running Flask/Werkzeug in Python 3.8 for a bit and don't have the same issue.

This should have been fixed a while ago, are you using the latest version?
