윈도우에서 mysql2 ruby gem이 아래와 유사한 이유로 설치가 안되는 경우 해결방법. (rails4, ruby2 에서 확인)

Building native extensions. This could take a while…

 1. 이 유


1. mysqlclient 또는 mysql connector가 설치되어 있지 않기 때문

2. mysql connector가 설치되어 있다 하더라도 경로 지정이 안되있는 경우

 

2. 해결방법


1) mysql c connector를 설치한다. [http://dev.mysql.com/downloads/connector/c/] (설치되어 있는 경우 생략)

2) 아래와 같은 방법으로 설치한다. 굵은 글씨 부분은 mysql connector가 설치된 환경에 맞게 수정한다.

C:\>gem install mysql2 –platform=ruby — ‘–with-mysql-lib=”C:\Program Files\MySQL\MySQL Connector C 6.1\lib” –with-mysql-include=”C:\Program Files\MySQL\MySQL Connector C 6.1\include”‘
