I'm new to the world of programming and I'm having a bit of a time resolving a bundling error with ruby on rails. I'm running OSX 10.9.1, RVM for Ruby management, and I am using ruby 2.1.1.

The error I receive is:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /Users/Removed/.rvm/rubies/ruby-2.1.1/bin/ruby extconf.rb checking for pg_config... no No pg_config... trying anyway. If building fails, please try again with --with-pg-config=/path/to/pg_config

checking for libpq-fe.h... no

Can't find the 'libpq-fe.h header

* extconf.rb failed *

Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. extconf failed, exit code 1

Gem files will remain installed in /Users/Removed/.rvm/gems/ruby-2.1.1/gems/pg-0.12.2 for inspection. Results logged to /Users/Removed/.rvm/gems/ruby-2.1.1/extensions/x86_64-darwin-13/2.1.0/pg-0.12.2/gem_make.out An error occurred while installing pg (0.12.2), and Bundler cannot continue.

After a little research I downloaded the Postgres App and put it into the Application directory. It appears I am still having a header problem as well, so I tried try specifying the include directory of the app. Still no resolution. Iv'e also came across some material relating to homebrew,but I'm at a loss for getting set up here. If I could have some help getting sorted out it would be greatly appreciated. Thank you in advance.

Edit:

rvm info :

ruby-2.1.1:

Checking to see if I'm in a subdirectory was a good idea, but sadly I'm not. I'm just trying to boot the server from the root directory of the application.

  • Maybe you accidentally created a new gem set for that directory? Can you run `bundle install` in the directory? What do you get if you run `rails -v` in that directory? – Beartech Feb 28 '14 at 02:38

Try doing what it says:

--with-pg-config=/path/to/pg_config

so re-run the install command like:

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

This is assuming you have the Postgres app in your Applications folder. You will run into other issues with Postgres.app, but it's worth it to work through them. Every "App" in OS X is really just a folder that you can look into. If you right click on the app and choose "show contents" you will get a new window that will let you browse the content of the app folder.

  • I managed to get passed my original error with: brew install postgresql and then running gem install pg Now when I call upon the rails server it's acting as if it seems to think I am not in a rails directory. Any idea what might be causing this? – user3358602 Feb 27 '14 at 04:20
  • I think I've seen that before, but can't remember what I did for it. I know I've sometimes gone as far as creating a new app by the same name in ANOTHER folder, then replacing all the files with my other directory. – Beartech Feb 27 '14 at 16:17
  • Can you update your question with what you've done so far and the error? It may have something to do with RVM. Can you post the info from running `rvm info` from the root folder of your rails app? Also are you sure you aren't in a sub folder like `app` when you run `rails s`? Just checking, as I've done that myself before. – Beartech Feb 27 '14 at 16:23
