Answer 1

Der Fehler in der Stack-Trace sichtbar ist:

Can't find the 'libpq-fe.h header 

Sie haben keine libpq Header, erforderlich für den Aufbau des PG-Adapter . Stellen Sie sicher, dass Sie PostgreSQL und die Dev-Abhängigkeiten installiert haben (das libpq-dev-Paket).

Auch müssen Sie Ihre Gemfile reinigen. Sie haben 3 gleichwertige group :development, :test do Deklarationen.

Plus, importieren Sie sowohl die Sqlite3 und PG Edelsteine ​​in der gleichen Umgebung. Treffen Sie eine Entscheidung über Ihre Datenbank und verwenden Sie nur eine davon.

Zu guter Letzt haben Sie keine Datenbank für die Produktion deklariert, daher wird Ihre Bereitstellung in der Produktion fehlschlagen.

Answer 2

Unter Linux installieren Sie einfach sicher, dass diese zwei

sudo apt-get install postgresql 
sudo apt-get install pgadmin3 
bundle install
