- OS: Debian 8
- PostgreSQL, Ruby and Rails installed
- Part of efforts to write a small Ruby on Rails reporting application which requires connection to PostgreSQL database.
- Attempt to install PostgreSQL database driver and got “missing library” error.
> gem install postgresql Building native extensions. This could take a while... ERROR: Error installing postgresql: ERROR: Failed to build gem native extension./usr/bin/ruby2.1 extconf.rb checking for pg_config... yes Using config values from /usr/bin/pg_config You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.
Because this is for connect to PostgreSQL database hence install libpq-dev
> sudo apt-get install libpq-dev
After that is completed
> gem install postgresql
No further error.
