wikibook / flask Goto Github PK

I am having some problems with the library version or dependency in chapter 5.
I am working with python 3.8, werkzeug version 2.0.1
This is the error I get.
`2021-08-10 11:15:00,684 - INFO - static folder : /home/jypark/Documents/GitHub/WebDevelopment/flask-repo/wikibooks/ch05/photolog/photolog/../static

I tried to downgrade the werkzeug version to 1.0.0 with pip install werkzeug==1.0.0
but then I get this error
`Traceback (most recent call last):

Did anyone else have the same problem?
Thanks in advance!

안녕하세요. 공부하다 오류가 발생해 더 이상 진행을 할 수가 없어 문의드립니다.

이클립스에서 ch02 hello.py 실행 시 아래와 같은 오류가 나는데
웹서버를 추가로 설치해야 하나요?

조치방법을 구체적으로 부탁드립니다.
