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
...

An error occurred while installing pg (0.17.1), and Bundler cannot

Make sure that `gem install pg -v '0.17.1'` succeeds before
bundling.

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.

Answer 3

sudo ARCHFLAGS="-arch x86_64" gem install pg

Answer 4

I uninstalled postgresql using home-brew ( I had used it to install postgresql before )
I installed the Postgres.app and this updated my PATH
I then had to stop the currently running postgresql db
I then was able to launch the Postgres.app and it started on port 5432
I then had to restart my terminal
Then I was able to run bundle and it worked.

Answer 5

In my particular instance I was trying to run bundle install on my first heroku app. I did all the items that #boobooninja listed (with slightly different paths, of course). What ended up working for me was a combination of two answers. I needed to
$ sudo su
$ env ARCHFLAGS="-arch x86_64" gem install pg -v '0.17.1'
By adding the -v 0.17.1 and specifying the version needed by heroku I was able to complete my bundle and proceed.

Answer 6

For ease of management and upgrading, etc. I have used the (PostgreSQL Application on my Mac with the following gem install (same as yours above).
gem install pg -- --with-pg-config=/Applications/Postgres__version__.app/Contents/MacOS/bin/pg_config
I have had no issues with this approach (versus a custom install or via Homebrew from which I have had a few problems).

Answer 7

Please make sure that you have the 'libpq-dev' package installed on your system
So try installing libpq-dev:
for Ubuntu systems: sudo apt-get install libpq-dev
on RHEL systems: yum install postgresql-devel
for Mac: brew install postgresql
Then install pg gem
$ gem install pg -v '0.17.1'
$ bundle

Answer 8

For me, the trick was to re-link Postgres 9.3.0
brew link postgresql

Answer 9

If you want to still be able to add gem 'pg' to your gemfile and use bundle install, and you know PostgreSQL and libpq-dev are installed (which I believe both should be since OS X ships with PostgreSQL) you need only tell your $PATH where to find pg_config. Try this:
$ ln -s /Library/PostgreSQL/9.1/bin/pg_config /usr/local/bin/pg_config
Make sure to replace 9.1 with whatever PostgreSQL version you have installed. And make sure wherever you're creating the link is in your $PATH. Once that's done, run bundle install to install the pg gem.
