Git 윈도우10에서 SourceTree가 다운될때

윈도우10에서는 Git클라이언트인 SourceTree 최신버전이 다운된다.
그래서 아래 링크에 있는 SourceTree 1.5.2를 받아서 설치하면 해결된다.
하지만 SourceTree 1.5.2는 파일을 add/commit할때 폴더별로 정렬이 안되어서 불편하다.
아직은 윈도우8.1이 가장 편리한 윈도우인것 같다.(최신 지원 기능 및 적은 업데이트)

다운로드

Redis 설치(Mac)

brew redis install
redis-server

        from bin/rails:4:in `<main>'

이를 해결하는 방법은 다음과 같다.
gem instasll pg --pre
gem list pg

확인결과 최신버전은 0.18.3이다.
그럼 Gemfile, Gemfile.lock에서 pg의 버전을 0.18.3으로 변경하면 해결 된다.
