Rails 5.2 업데이트 시 문제점 정리
Rails 5.2 업데이트 시 문제점 정리
개인 프로젝트로 관리중인 rails web server 를 ruby version 을 올리는 김에 같이 업데이트를 하려고 합니다.
기존 버전은 rails 5.0.3 이었고, 이번에 rails 5.2.0 으로 올리고 만난 에러들을 기록하려고 글을 씁니다.
Update
먼저 Gemfile.lock 을 지우고 과감하게 update 룰 합니다.
rm Gemfile.lock
bundle update
Gemfile 을 열어보면 rails 5.2를 확인할 수 있습니다.
업데이트가 안되었다면, 강제로 rails 만 업데이트 해줍니다.
bundle update rails -v 5.2.0
내가 만난 문제들
“Rack::Cors” String 문제
업데이트가 잘 되었으면 console 을 실행합니다.
rails c
output
$ rails c

위의 에러가 났습니다.
이 에러는 application.rb 내부의 Rack::Cors 문제입니다. 아래 링크에 해결책이 자세히 나와있습니다.

엄청나게 긴 에러를 만납니다.
원인을 찾아보니, 원인은 단순합니다.
사용하지 않는 coffeescript 파일들이 프로젝트에 존재하고 있었습니다.
아래 명령으로 확인후 삭제 해줍니다.
$ find . -name "*.coffee"
그러고도 에러가 난다면 **cache*** 문제입니다.
cache 를 삭제해줍니다.
$ rake tmp:cache:clear
관련 내용은 여기서 확인 가능합니다.
web-console 문제
위의 에러에서
NameError: uninitialized constant Mime::HTML
이런 에러가 있는데 이건web-console버전 문제였습니다..
web-console을 업데이트 해줍니다.
$ bundle update web-console
다시 실행합니다.
결론
여기까지 제가 해결한 문제였습니다.
