bundle failing - Can't find the PostgreSQL client library (libpq) [duplicate]

Question

I think I have tried all the suggestions I could find regarding this issue. Still not working for me.

When I try to bundle ...

$ bundle ...  Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.      /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb checking for pg_config... yes Using config values from /usr/local/bin/pg_config checking for libpq-fe.h... yes checking for libpq/libpq-fs.h... yes checking for pg_config_manual.h... yes checking for PQconnectdb() in -lpq... no checking for PQconnectdb() in -llibpq... no checking for PQconnectdb() in -lms/libpq... no Can't find the PostgreSQL client library (libpq) *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

An error occurred while installing pg (0.17.1), and Bundler cannot continue. Make sure that `gem install pg -v '0.17.1'` succeeds before bundling. 

Output from previous code...

$ which bundle /Users/Loren/.rvm/gems/ruby-2.1.1@global/bin/bundle  $ which gem /Users/Loren/.rvm/rubies/ruby-2.1.1/bin/gem  $ which psql /usr/local/bin/psql 

I tried to uninstall postgresql using Homebrew and reinstall and that didn't help.

I tried...

ARCHFLAGS="-arch x86_64" gem install pg 

and that completes successfully but then when I run bundle I still get the same error.

I tried ...

gem install pg -- --with-pg-config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config 

and that didn't work.

I tried ...

gem install pg -v '0.17.1' -- --with-pg-config=/usr/local/Cellar/postgresql/9.3.2/bin/pg_config 

and that didn't work either.

I am not sure what else to try at this point. Thanks for any help.

Answer 1

My solution ended up at this

ARCHFLAGS="-arch x86_64" bundle install 

Answer 2

Based on this post's answer and it worked for me (Yosemite OSX 10.10), you can try the following:

$ sudo su  $ env ARCHFLAGS="-arch x86_64" gem install pg 

You don't have to reinstall pg from homebrew.
