원래 명령어가 streamlit run app/frontend.py --server.port 30001    라고 했을 때 뒤에 옵션 추가하면 된다.                           

streamlit run app/frontend.py --server.port 30001

 

 

 

해결방법

뒤에 --server.fileWatcherType none 옵션을 붙여준다. 

streamlit run app/frontend.py --server.port 30001 --server.fileWatcherType none

streamlit run app/frontend.py --server.port 30001 --server.fileWatcherType none

그러면 해결

You can now view your Streamlit app in your browser.

메시지가 뜨면 성공
