로드 오류 - Ruby on Rails에서 MySQL 사용하기

Question

Ruby on Rails에서 SQL을 사용하려고 시도해 왔지만 제대로 작동하지 않는 것 같습니다.

저는 SQLite를 거의 포기 했으므로 이제 MySQL에 중점을 둡니다. 나는 프로그램을 완전히 설치했고 그것은 독자적으로 작동한다. 그러나 Ruby on Rails에서 작동하도록 할 수는 없습니다.

다음은 새 프로젝트를 시작하고 데이터베이스를 MySQL로 선택할 때 표시되는 메시지입니다. , 내가 RubyVersionManager, DevKit을 포함하여 관련 StackExchange 질문/답변에 걸쳐 온 거의 모든 시도

Post-install message from mysql2: 

================================================================================ 
====================== 

    You've installed the binary version of mysql2. 
    It was built using MySQL Connector/C version 6.0.2. 
    It's recommended to use the exact same version to avoid potential issues. 

    At the time of building this gem, the necessary DLL files where available 
    in the following download: 

    http://dev.mysql.com/get/Downloads/Connector-C/mysql-connector-c-noinstall-6.0 
.2-win32.zip/from/pick 

    And put lib\libmysql.dll file in your Ruby bin directory, for example C:\Ruby\ 
bin 

================================================================================ 
====================== 

그러나, 나는 다음과 같은 오류가 발생합니다 다양한 .dll 및 .a 파일을 C/Ruby/Bin 등으로 옮긴다. 그러나 운이별로 없다.

이 솔루션은 모든) = 지금까지 잘 진행되어

이 http://dev.mysql.com/get/Downloads/Connector-C/mysql-connector-c-noinstall-6.0.2-win32.zip/from/pick에 압축을 다운로드하고 libmysql을 복사하려면 .dll 파일을 루비 디렉토리 (C :/Ruby200/bin)에 복사하십시오. 그러면 Rails 애플리케이션에서 MySQL에 액세스 할 수있다.
