Trouble Getting the Rails Server Started

Question

When I run \'rails server\' I get the following error:

Could not find gem \'sqlite3 (>= 0, runtime)\' in any of the gem sources listed in your Gemfile.
         


        

Answer 1

If you have problems talking about /usr/local/bin/ruby extconf.rb checking for sqlite3.h then it's probably something to do with macports.

First, make sure you have xcode installed. Run:

gcc

and you should get:

i686-apple-darwin10-gcc-4.2.1: no input files

If you do, then let's install homebrew

Then, a list of commands to install homebrew, update rubygems, and upgrade rails

brew install sqlite
gem update --system
gem install bundler
gem install rails -v=3.0.8

Then, to check, rails -v should output Rails 3.0.7
