Soy make $ gem install pg -v ''0.14.1'' Pero esto no es de ayuda

Ayudame por favor. Gracias.

Perdón por este texto Tu publicación no tiene mucho contexto para explicar las secciones de código; por favor explique su escenario más claramente.

En Mac OS X, ejecute así:

gem install pg -- --with-pg-config=***/path/to/pg_config***

***/path/to/pg_config*** es la ruta a pg_config

En Mac, asegúrese de que su postgres esté vinculado. Puedes hacerlo por

brew link --overwrite postgresql

Esto solucionó el problema para mí.

En los sistemas Fedora / RHEL, este fue el truco:

sudo yum install libpqxx-devel

Esto funcionó para mí:

sudo gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config

Esto se responde en No se puede encontrar el encabezado ''libpq-fe.h cuando se intenta instalar la gema pg

Dependiendo de tu entorno:

Mac: brew install postgresql
Ubuntu : sudo apt-get install libpq-dev
RHEL : yum install postgresql-devel

A continuación, ejecute gem install pg nuevamente

Prueba esto:

brew instalar postgresql
joya instalar pg
paquete de instalación

Solo haz esto

$ sudo apt-get install libpq-dev

Tuve este problema con un servidor de Jenkins en Amazon AMI.

$ pg_config | grep VERSION VERSION = PostgreSQL 9.4.9

Luego, dependiendo de la versión que necesite, puede instalar la lib requerida

$ sudo yum list postgresql* | grep devel postgresql92-devel.x86_64 9.2.18-1.59.amzn1 @amzn-main postgresql94-devel.x86_64 9.4.9-1.67.amzn1 @amzn-main postgresql8-devel.x86_64 8.4.20-5.52.amzn1 amzn-main postgresql93-devel.x86_64 9.3.14-1.62.amzn1 amzn-main postgresql95-devel.x86_64 9.5.4-1.71.amzn1 amzn-main

Luego puede instalar la versión correspondiente, en mi caso para la versión 9.4:

sudo yum install postgresql94-devel

Yo uso Ubuntu-16. Y utilizo el método que se muestra aquí: https://www.postgresql.org/download/linux/ubuntu/ para instalar postgresql-9.6; Y uso "sudo apt-get install libpq-dev" para instalar el devlib. Pero todavía no puede funcionar. Entonces utilizo el método ln para establecer un enlace blando, aquí está: sudo ln -s /usr/include/postgresql/libpq-fe.h /usr/include/ ; sudo ln -s /usr/include/postgresql/postgres_ext.h /usr/include/ Y finalmente resuelvo el problema.

prueba esto:

sudo apt-get install libpq-dev gem install pg

¡Serían obras!
