Faites juste ceci

$ Sudo apt-get install libpq-dev

Ceci est résolu dans Impossible de trouver l'en-tête 'libpq-fe.h lors de la tentative d'installation de pg gem

En fonction de votre environnement:

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

Puis relancez gem install pg

Essaye ça: 

  1. brasser installer postgresql
  2. gem installer pg
  3. installation groupée

Sur les systèmes Fedora/RHEL, le problème a été résolu:

Sudo yum install libpqxx-devel

Sous Mac OS X, procédez comme suit:

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

***/path/to/pg_config*** est le chemin d'accès à pg_config

J'ai eu ce problème avec un serveur Jenkins sur Amazon AMI.

$ pg_config | grep VERSION
VERSION = PostgreSQL 9.4.9

Ensuite, selon la version dont vous avez besoin, vous pouvez installer la bibliothèque requise.

$ 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

Ensuite, vous pouvez simplement installer la version correspondante, dans mon cas pour la version 9.4:

Sudo yum install postgresql94-devel

Sur mac, assurez-vous que votre postgres est lié. Vous pouvez le faire en

brew link --overwrite postgresql

Cela a résolu le problème pour moi.

essaye ça:

Sudo apt-get install libpq-dev
gem install pg

ce serait des travaux!

Pour Amazon Linux:

Sudo yum install postgresql-devel

puis relancez votre commande

J'utilise Ubuntu-16. Et j'utilise la méthode montrée ici: https://www.postgresql.org/download/linux/ubuntu/ pour installer postgresql-9.6; Et j’utilise "Sudo apt-get install libpq-dev" pour installer devlib.Mais cela ne fonctionne toujours pas. Donc, j’utilise la méthode ln pour établir un lien symbolique, la voici: Sudo ln -s /usr/include/postgresql/libpq-fe.h /usr/include/; Sudo ln -s /usr/include/postgresql/postgres_ext.h /usr/include/ Et je résous enfin le problème.

Cela a fonctionné pour moi:

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