Installing Pg -V 0.17.1

Installing pg -v 0.17.1

Looks like you are missing pre-requisite libraries.

sudo apt-get install libpq-dev postgresql-devel

Then install pg

gem install pg

gem install pg -v '0.17.1' not working for some reason

I had some problem same as you when i installed gem 'pg' on centos or ubuntu.

For centos, you can do this:

yum install postgresql-libs
yum install postgresql-devel

Then run gem install pg again.

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

I'm on a Mac running Mavericks. My solution was to install Postgres.

And then in terminal install using homebrew with the configuration:

gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/latest/bin/pg_config

Note: This answer has been edited to use the latest symlink that is currently included in shipping versions of the Postgres app.

Previous versions suggested:

gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config

Could not find pg-0.17.1 in any of the sources

An alternative solution: Download the postgresql.app:

Create or modify the config/database.yml file, adding the following configuration:

development:
  adapter: postgresql
  encoding: unicode
  database: name_of_app_development
  pool: 5

Error updating pg gem from 0.17.0 to 0.17.1 for Mac OS X 10.9.1

The easiest way is to install Postgres.app.

Then do:

$ gem install pg -v '0.17.1' && bundle update

Edit: Do not forget to add the relevant directories into your PATH.

Not able to run the RoR project using rails s. Could not find pg-0.17.1 in any of the sources

Try installing libpq-dev

sudo apt-get install libpq-dev

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