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

From your Rails directory:

cd ..
cd rails-root
ruby -v
gem list sqlite3
bundle install
gem list sqlite3
bundle exec rails server

What might be happening is you're bundling in a Rails app that has an .rvmrc file. I've seen cases where you bundle under a version of Ruby that doesn't match the .rvmrc file or some other mismatch so when you bundle sqlite3 it isn't under the same version of Ruby that rails is using when you run the app.

Changing out of the directory and back into it, and running rails server prefixed with bundle exec are my two suggestions.
