PG камень на OSX Yosemite не обновляя

Question

Рубин Версия 2.0.0p481

Рельсы Версия 4.1.8

PG версии 0.18.1

Я пытаюсь следовать Heroku-х Getting Started with Heroku Tutorial. Все работает нормально, пока мне не нужно запускать приложение локально и перенести базу данных. Команда bundle exec rake db:create db:migrate дает мне ошибку:

Could not find gem 'rails (= 4.1.8) ruby' in the gems available on this machine. 
Run `bundle install` to install missing gems. 

Когда я бегу bundle install:

Я пробовал все, что я могу найти, используя gg gg на google. Я понятия не имею, что случилось. Любая помощь высоко ценится! Я запускаю приложение Postgresql, и раньше я разрабатывал приложения, используя драгоценный камень PG на этой машине, только после обновления до Yosemite.

Answer 1

Похоже, что дергает за pg_config значения из /usr/local/bin/pg_config однако я имел лучший опыт с приложением Postgres, когда говорю это, чтобы использовать собственный pg_config значение.

Вы можете сделать это с with-pg-config флагом:

gem install pg -v '0.18.1' -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config 

Вы должны найти правильный путь для вашей машины. Перейдите в папку «Приложения», щелкните правой кнопкой мыши на Postgres.app и выберите «Показать содержимое пакета», и вы можете найти файл pg_config.

Update:

Некоторые очень любезны лицо было бдительно уточненный список pg_config путей на Cannot install pg gem in Mavericks with Postgres.app
