Rails pg gem Incompatible library version
Solution 1
Try:
$ gem install pg
$ gem pristine --all
Solution 2
It looks as if you might be suffering from this bug: https://bitbucket.org/ged/ruby-pg/issues/229/pg_exit-improperly-linked-when-using-rvm
The libruby version should be different, apparently.
However: I have the same error message, and my libruby is correct, so I think that there might be more going on...
Solution 3
I get the same error when I call in console rails c
. Calling bundle exec rails c
removed that error.

I'm getting the following 'incompatible library version' error when I try and access my Ruby on Rails website in development mode.

I've tried updating PostgreSQL using yum update, then gem uninstall pg and gem install pg. But I continue to get the same problem. The gem itself installs without any errors.
I'm not really sure how to debug further. What do I need to do to install, update or reference the necessary compatible libraries?
The server is running:
- CentOS 6.7
- psql (PostgreSQL) 8.4.20
- ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]
- rails 4.2.4
- pg gem 0.18.4
Thanks
