모든 것은 mysql서버를 설치하지 않고 rails를 하려고 한 것에서 시작되었다. 아래와 같은 문제의 경우, 사용하는 ruby의 플렛폼(x86/x64 여부)와 관련된 문제다. 에러 내용이 link 에러여서 좀 더 유심히 보았다. 그랬더니 얻은 결론! mysql connector는 x64 버젼이고 루비는 x86이였던 것이다. 작동 플렛폼이 다르니 당연히 발생하는 문제였다. 아이구… 어쨋든, 여기에서 x86버젼 커넥터를 받아서 설치하여서 경로를 약간 수정해 다시 실행하였더니 성공적으로 설치되었다.
1. 해결 방법
1) mysql connect (x86)버젼을 다운로드 받는다.
2) 아래 명령을 실행한다.
C:\Ruby193\bin>gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\Program Files (x86)\MySQL\MySQL Connector C 6.1\lib" --with-mysql-include="C:\Program Files (x86)\MySQL\MySQL Connector C 6.1\include"'
