Problemas para instalar la gema de pg

Question

Intentar instalar la gema de pg me da errores.

Estoy usando Ruby 1.9.3-p125 construido usando rbenv/ruby-build. Instalé PostgreSQL usando el instalador de un clic. Puedo conectarme a la base de datos usando pgAdmin. Me estoy quedando sin ideas.

% gem install pg                                                  ~ 
Building native extensions. This could take a while... 
ERROR: Error installing pg:

Answer 1

No estoy seguro de cuál de los siguientes pasos solucionó definitivamente este problema. Pero como mu es demasiado breve, el problema fue mezclar binarios de 32 bits y 64 bits.

• primero, he instalado este 64-bit version of PostgreSQL

• segundo, me desinstalado cualquier instalación antigua Homebrew OpenSSL

  $ brebaje desinstalación openssl

• tercero, he instalado el 64 bits versión de OpenSSL con Homebrew

  $ brew instalar --64 bits openssl

• Por último, al instalar la gema pg, he cambiado el LDFLAGS para que apunte a la versión de 64 bits de OpenSSL

  $ gem install pg - with-ldflags = '- L/usr// Almacén/openssl/0.9.8s locales
