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

Answer 1

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
