안녕하세요.
Do It Django 책 덕분에 장고 열심히 공부 중에 있습니다.
현재 로컬 환경에서 블로그 작성은 모두 마친 상태로 「도커로 이사 준비하기」 부분 진행 중에 있습니다.
도커 관련 각종 설정 마친 상태로 도커 빌드 하면 잘 넘어가다가 다음과 같은 오류로 더 이상 진행이 되지 않습니다.

==================================
에러나는 패키지 삭제하고 다시 빌드하면 다른 패키지에서 또 에러나고...
책과 같은 버전에 맞춰서 다시 만들어야 할까요?
추가로 아래 패키지에서도 에러가 발생합니다.
idna==3.2
PyJWT==2.1.0
해결 방법 좀 알려주시면 감사하겠습니다.

안녕하세요. cryptography 설치과정에서 문제가 생기고 있네요.
저희가 책을 쓸 때와 달리, AWS의 우분투를 활용할 경우, cryptgraphy 설치가 잘 안되는 현상이 보고되었습니다.
이 부분에 대해 저희 doitdjango의 블로그에 cryptography 오류시 대처법 이라는 글로 안내해 두었으니, 참고하시기 바랍니다.
혹시 글로만 파악이 어려우시다면, 인프런 동영상 강좌를 참고해주세요. 이 문제가 발생하지 않도록 작업하는 과정을 동영상으로 찍어놓았습니다. 유료강좌이지만, 도커 부분부터는 무료로 보실 수 있도록 공개해두었습니다.

덕분에 해결했습니다.
추가로 idna==3.2 → idna==2.10으로 변경해야 에러가 발생하지 않습니다.
감사합니다.
