La instalación de la gema PostgreSQL con ''gem pq'' falla con ERROR: no se pudo construir la extensión nativa de la gema (3)
Estoy aprendiendo Ruby on Rails y tratando de desarrollar una aplicación. En mi aplicación, estoy tratando de usar la base de datos SQLite por defecto en el Modo de Desarrollo y PostgreSQL en el Modo de Producción . Pero recibo el siguiente error al intentar instalar la gema de pg usando: gem install pg

Si está utilizando Ubuntu intente instalar el siguiente archivo lib
sudo apt-get install libpq-dev
y luego joya instalar pg
trabajó para mi.
Tienes que hacer esto
sudo apt-get install libgmp-dev libpq-dev
y entonces
gem install pg
para aquellos que llegaron a esta búsqueda en google si libpq-dev no funcionó o arrojó otros errores, tuve el mismo problema, intente actualizar su sistema y obtener el ruby div-kit
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ruby1.9.1-dev
luego reinicia después de esto solo inténtalo de nuevo
