처음보는 모듈이었지만 일단 모듈을 찾지 못했다고 하니, pip install werkzeug를 하여 설치를 시도해보았다.

 

(base) E:\Project\universe\Real-Time-Face-Expression-Recognition-master>pip install werkzeug
Requirement already satisfied: werkzeug in c:\anaconda3\lib\site-packages (0.14.1)

 

그러나 현재 내 컴터에는 werkzeug가 설치(0.14.1 버전)가 되어 있었다. 

 

스택오버플로우를 보면 아래의 답변에서 0.15.4를 설치하니 해결이 되었다고 한다.

 

pip install werkzeug==0.15.4

(base) E:\Project\universe\Real-Time-Face-Expression-Recognition-master>pip install werkzeug==0.15.4

위와 같이 0.15.4 버전을 설치하니, 에러가 발생하지 않는다. -끝-
