Rails - Gem Error while installing pg (1.1.3), and Bundler cannot continue

Question

I am still fairly new to Rails. I am trying to push to Heroku and I am getting errors

The first error is when I run a Bundle Install I get this error message

Answer 1

I had the exact same problem, and solved it by running sudo apt install postgresql-contrib libpq-dev. Then bundle worked just fine.

Answer 2

if you're using OSX, you could try running

brew install postgresql

and then installing the gem

Answer 3

try instaling with pg-config like this:
gem install pg -v 1.1.3 -- --with-pg-config=/usr/pgsql-9.X/bin/pg_config.

In pg-config path mention the posgtres version installed in you're system.
