Getting Errors While Installing

nikilster commented 10 years ago

Tried this 3-4 times (uninstalling ruby from scratch) and keep getting an error when I try to do "gem install mosql".

Installing on an AWS EC2 instance after following this guide: https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm

Thanks in advance for the help!

You probably need to install libpq-dev -- that's a native C dependency that the pg gem needs in order to compile.

wow okay that was amazing. I spent several hours trying to fix this. Thanks!

Just ran into this. Curious, why is this not listed as a dependency in the mosql package or somewhere upstream? Surprise dependencies are a pain.
