4-3 마지막 웹서비스 개시에서 실행이 되지 않습니다

[DRamghi]

안녕하세요. 좋은 책을 만나게 되어 기쁜 마음으로 공부하고 있습니다. 그런데 4-3에서 플라스크 웹서비스 개시에서 계속 로딩만 되고 실행이 되지 않습니다.

실행하면 아래와 같이 나오네요. 어떻게 하면 될지 알려주시면 감사하겠습니다.

안녕하세요 @DRamghi 님, 해당 에러는 authtoken이 잘못 입력되어서 발생한 문제로 보입니다. 다음과 같이 입력해서 다시 실행해보시겠어요?

현재

!mkdir /root/.ngrok2 && echo "authtoken: {2H8...Dw4}" > /root/.ngrok2/ngrok.yml

수정

!mkdir /root/.ngrok2 && echo "authtoken: 2H8...Dw4" > /root/.ngrok2/ngrok.yml

자세한 내용은 다음 이슈를 참고하셔도 좋을 것 같습니다.
