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

Answer 1

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 2

My solution ended up at this

ARCHFLAGS="-arch x86_64" bundle install

Answer 3

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 4

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 5

sudo ARCHFLAGS="-arch x86_64" gem install pg
DID THE TRICK FOR ME...thanks for tip on a thread given by Jakob@github

My system: OSX 10.9.4, Ruby 2.0.0, local ( non-homebrew) Postgresql 9.3.5

Building native extensions.  This could take a while...

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).
