오류 : MySQL 설치 오류 : 오류 : 보석 기본 확장자를 빌드하지 못했습니다.

Question

저는 루비 초보자입니다. MySQL을 보석에 설치할 때 오랜 시간이 걸리는 문제가 있습니다. 컴퓨터 시스템이 OSX 10.10이라는 것을 알고 있으므로 brew에서 MySQL을 설치합니다. 나는 stackoverflow에서 찾을 수있는 모든 솔루션을 시도했지만 그것을 해결할 수 없습니다. 같은 :

1. Install xcode-tool 
2. GEM install mysql2 -- --with-mysql-dir=/usr/local/Cellar/mysql/5.5.25a 
3. List itgem install mysql2 -- --with-opt-dir=/usr/local/Cellar/mysql/5.5.25ae 

등등 ....

Answer 1

행복합니다. 문제가 해결되었습니다. 명령을 실행할 때 gem update .i 오류가 발생했습니다. 문제는 보석으로 인한 것 같습니다. 그래서, gem get stable 명령을 실행하고 brew unlink libyaml && brew link libyaml 명령을 실행하면 mysql이 성공적으로 설치됩니다 !!!
