lol @ Segedunum

I got the error: Please install the postgresql adapter: gem install activerecord-postgresql-adapter (no such file to load — pg)

and I read on this blog so I did: sudo gem install pg

and Yay! it’s working Thank you,

Thanks for the post! This helped me using Taps and heroku to pull data to a local postgres db. Taps failed with a mysterious errror: Failed to connect to database: Sequel::AdapterNotFound -> LoadError: no such file to load -- pg

Installing ruby-pg solved it.

Don't know if it's what you're looking for...

joshkim, where did you post the solution? I’ve been stuck all day trying to get through this. Thanks!

Yeah, this was a specific issue with Mac OS X. It eventually got
resolved. I posted in another post with the solution.

For what it's worth, I fixed this problem on my Fedora 9 system with:

sudo yum install ruby-devel sudy gem install pg

I’ve just realised the ruby-pg actually is the gem called postgres – at least they both have exactly the same version at the time of writing – 0.7.9.2008.01.28. We’ve been using postgres for some time with great success.

I had the problem with:

Building native extensions. This could take a while... ERROR: Error installing pg: ERROR: Failed to build gem native extension.

/usr/bin/ruby1.8 extconf.rb install pg extconf.rb:1:in `require': no such file to load -- mkmf (LoadError) from extconf.rb:1

This solved by running:

sudo aptitude install ruby rubygems ruby1.8-dev

I've done a couple of rails installs now on laptops and found myself in the exact same situation as you when installing on a new box -- real headscratcher. My problem was this: I'd installed rubygems via macports but neglected to install a fresh copy of rake via rubygems, which meant that when doing a rake db:migrate, it would find OS X's native rubygems. I only figured this out because script/server (which relies on the ruby binary) was working where rake was not.

A 'gem install rake' (and a new terminal window to clear the bash path cache -- try saying that out loud) fixed me right up.

If this command doesn't return three binaries in the same directory for you, you might be in the same boat:

$ which ruby rake gem

-john
