Can't run cloned repository

Question

How do I download my old code from github? I made a mistake on my app, and when I try to download the old zip file from github and run it I get an error.

I think I'm doing it right, don't I just need to clone the repository? When I do, i get this error when I try to run the server:

An error occurred while installing pg (0.17.0), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.0'` succeeds before bundling.

and when I run bundel install I still get the error.

I also get this error:

bundle install doesn't work and I still get the error along with this one:Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension

Answer 1

If you have installed Mavericks, that is the source of your problem. I had to install another gem with native dependencies that needed to be compiled after I installed Mavericks, and some changes as to which compiler Mavericks uses to compile gem dependencies creates problems. In your case, I would suggest you pick one of the solutions in this answer to resolve your PG installation problems.

It ssems to me that you do not have install Postgres. Install it and try bundle install again. How install Postgres on Ubuntu (of course you can have another system :) ) - https://help.ubuntu.com/community/PostgreSQL
