* 해결방법

 

1.  (실패) node-pre-gyp 설치

에러에서는  node-pre-gyp을 설치하라고 하고 

인터넷에서는 node-gyp을 설치해보라고 함. (현재 nodejs v12.16.3 버젼을 쓰고 있음) 

npm install -g node-gyp
npm nstall -g node-pre-gyp 

=> 둘다 실패.

 

 

2. (실패) 버젼을 낮추어서 설치

node-pre-gyp install --fallback-to-build

=> 실패

 

 

3.  (성공) 관리자 권한으로 cmd 실행 후 

npm install --global windows-build-tools

후에 다시 

npm install bcrypt --save

bcypt가 속도문제로 내부적으로 c or c++을 사용해서 윈도우 필수적으로 c, c++을 설치해서 다른 언어를 사용하는 라이브러리를 지원할 수 있게 해주는 것 

=> 해결함. 

 

4.  이것도 안되면 바이너리를 설치
