Instalando a gem do PostgreSQL no Rails 3

October 26, 2011 at 8:52 pm 1 comment

Recentemente, após instalar o dmg do PostgreSQL 9.1, fui usar a gem pg (gem do Postgres) e tomei uns erros estranhos:

checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
--with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/Users/hannelitavante/.rvm/rubies/ruby-1.9.2-p180/bin/ruby
--with-pg
--without-pg
--with-pg-dir
--without-pg-dir
--with-pg-include
--without-pg-include=${pg-dir}/include
--with-pg-lib
--without-pg-lib=${pg-dir}/lib
--with-pg-config
--without-pg-config
--with-pg_config
--without-pg_config


Gem files will remain installed in /Users/hannelitavante/.rvm/gems/ruby-1.9.2-p180/gems/pg-0.11.0 for inspection.

Bizarramente, no MacOSX 10.6+, ele dá uns paus muito loucos. para resolver, basta fazer isso:


export PATH=PATH_DO_SEU_POSTGRES/bin:$PATH
export ARCHFLAGS='-arch x86_64'
gem install pg
