개발 환경 구축하기 in MacOs - 문제

 

Flutter 문서 제공 사이트 - https://flutter-ko.dev/docs 아름답게 한국어로 번역되어있다.

Flutter는 기본적으로 웹 Document를 제공해줘서 설치하는 데에는 크게 문제가 될 것 같지는 않았다.

게다가 한글 번역이 된다니 너무나 놀라웠다. 하지만 언제나처럼 예상은 빗나가는 법이 었다.

(- 모든 문서가 번역되어 있는건 아니었습니다. :D)

문제 발생

flutter doctor -v

해당 명령어를 검색하면 환경 구축시 문제되는 부분을 조금 더 자세하게 볼 수 있다.

hyeokchani-MacBook-Pro: ~ hyeokchani$ flutter doctor -v

다음과 같이 Flutter와 Dart 플러그인을 Android Studio에서 인식을 하지 못하는 것이 었다.

해결

hyeokchani-MacBook-Pro:~ hyeokchani$ flutter upgrade
Flutter is already up to date on channel stable
Flutter 1.22.5 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 7891006299 (6 weeks ago) • 2020-12-10 11:54:40 -0800
Engine • revision ae90085a84
Tools • Dart 2.10.4

hyeokchani-MacBook-Pro:~ hyeokchani$ flutter channel beta
Switching to flutter channel 'beta'...
git: Switched to a new branch 'beta'
git: Branch 'beta' set up to track remote branch 'beta' from 'origin'.
Successfully switched to flutter channel 'beta'.
To ensure that you're on the latest build from this channel, run 'flutter upgrade'

아마 오류가 있는 git branch를 switch 해줌으로써 새롭게 데이터를 받아올 수 있는 환경을 만들어준 것 같다.

그러면 다음과 같이

hyeokchani-MacBook-Pro:~ hyeokchani$ flutter doctor -v

해당되던 문제도 해결된 것을 볼 수 있었다.

이후 beta channel로 업그레이드 해주면 된다.

 

hyeokchani-MacBook-Pro:~ hyeokchani$ flutter upgrade
Flutter is already up to date on channel beta
Flutter 1.25.0-8.3.pre • channel beta • https://github.com/flutter/flutter.git
Framework • revision 5d36f2e7f5 (8 days ago) • 2021-01-14 15:57:49 -0800
Engine • revision 7a8f8ca02c
Tools • Dart 2.12.0 (build 2.12.0-133.7.beta)

이후에는 Android Studio에서도 환경 변수(Path)가 잘 연결되었는지 확인해본다.

 

 

마지막은 switch 했던 branch를 다시 복구하는 과정이다.

hyeokchani-MacBook-Pro:~ hyeokchani$ flutter channel
Flutter channels:
master
dev
* beta
stable

hyeokchani-MacBook-Pro:~ hyeokchani$ flutter channel stable
Switching to flutter channel 'stable'...
git: Switched to branch 'stable'
git: Your branch is up to date with 'origin/stable'.
Successfully switched to flutter channel 'stable'.

해당 문제를 해결하기 위해서 비슷한 오류가 있는 블로그를 찾았습니다.

그 블로그를 통해 많은 도움을 받을 수 있었고 비록 운영체제는 달랐지만 같은 명령어로 호환이 되게 만들었다는 것에 flutter를 보고 놀라웠습니다.

 

해결 방법 참조.
