[Flutter/AndroidStudio 삽질 일기] flutter doctor 왜 오류나는데

나는 flutter sdk를 멍청하게 지워서(D에 저장해둬서 프로젝트 파일인줄 앎;;;) 

다시 그대로 깔았는데 오류가 발생했었음

 

뭘 할때는 무조건 cmd 다시 켜기 

flutter doctor을 쳤는데 이렇게 뜸

D:\>flutter doctor
Doctor summary (to see all details, run flutter doctor -v):

1.  [!] Android Studio (version 2022.1)                
       X Unable to find bundled Java version.  해결법

 

- 안드로이드스튜디오 저장 위치로 이동 (설치 위치 지정 안했으면 C:\Program Files\Android\AndroidStudio)

-  jbr 폴더 내 파일 전체 복사

- jre 폴더에 붙여 넣기 

- 해결

 

컴맹이라 오류 날까 고민했는데 그냥 다시깔자 마인드로 했더니 해결 완료!!!

2-1) flutter doctor을 처음한 사람이라면

- 안드로이드스튜디오의 sdk Manager

- Android Studio - SDK Manager - System Settings

- SDK Tools에 Android sdk command-line tools(latest)눌러서 apply

- 해결

 

2-2) 나같은 바보라면 

- 안드로이드스튜디오의 sdk Manager 

- Android Studio - SDK Manager - System Settings 가서 show Package Details클릭

- SDK Tools에 Android sdk command-line tools(latest) 체크해제, 8.0버전만 apply 

-   C:\Users\user\AppData\Local\Android\Sdk\cmdline-tools 가서 8.0 >> latest로 변경

- 해결!!
