물어볼곳도 없고 하다보니 이렇게 질문드리게 되었습니다 ㅠㅠ

XE3 설치 후 익스텐션 설치 부분에서 해결이 안되고 있습니다..

AWS Lightsail로 설치했는데 도통 원활하게 설치가 안되서 곤욕중입니다. ㅠ

내용을 보아하니 컴포저 1버전을 사용할수 없으니 2버전으로 업그레이드 하라는걸까요?

sudo composer self-update 하고 2.3.5로 올린 상태에서 하면 "시스템에 오류가 있습니다. 관리자에게 문의하세요."라고 뜨고, composer upgrade라고 하면

  Problem 1
    - Root composer.json requires wikimedia/composer-merge-plugin 1.3.1 -> satisfiable by wikimedia/composer-merge-plugin[v1.3.1].
    - wikimedia/composer-merge-plugin v1.3.1 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.3.0] but it does not match the constraint.
  Problem 2
    - Root composer.json requires xpressengine/installer ~1.1.1 -> satisfiable by xpressengine/installer[1.1.1, 1.1.2].
    - xpressengine/installer[1.1.1, ..., 1.1.2] require composer-plugin-api 1.1.* -> found composer-plugin-api[2.3.0] but it does not match the constraint.

라고 뜹니다;;

계속 반복이에요.. xe 가이드처럼 $ sudo composer self-update 1.8.6했다가 2.3.5로 올렸다가 XE는 문의해도 답도없고 ㅠㅠ

답답하네요;
