v8 빌드 GN에서 오류가 발생했습니다

Question

소스 코드 (link)에서 정적 라이브러리를 빌드 할 수 없기 때문에 v8 엔진을 배우기 시작했고 매우 초기 단계에 쌓여있었습니다. 나는이 가이드 에 단계적으로 갔다하지만 난 내 V8 로컬 복사본이 D에 배치됩니다

python tools/dev/v8gen.py x64.release 

을 실행에 오류가 :

저는 크롬 제작 과정을 이미 읽고 인터넷에서 설명한 비슷한 문제를 확인했지만 실제로 도움이되는 것은 없습니다.

Answer 1

Windows 10 독립 실행 형 SDK를 설치하십시오. https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk

Windows 10 SDK를 설치하기 위해 VS2015를 선택해도 cdb.exe가 설치되지 않습니다.

Answer 2

DEPOT_TOOLS_WIN_TOOLCHAIN ​​= 0으로 설정했는지 확인하십시오. Chromium의 depot tools instructions 및 requirements도 참조하십시오.
