this is how I solved

      gem 'sqlite3'


     gem 'activerecord-jdbcsqlite3-adapter', :require => 'jdbc-sqlite3', :require=>'arjdbc'

I followed the advice in the error message and added the line


in the .jrubyrc file in my home folder (it didn’t exist, I had to create it).

Yes, I did similar to Hendie… I performed this ~~~ export JRUBY_OPTS=”-Xcext.enabled=true” ~~~ Before I ran my ~~~ bundle install –without production ~~~

Btw, you shouldn’t be getting issues with ‘pg’, but only with ‘sqlite3’, because you are running ‘–without production’ which will exclude the gem ‘pg’ line from being used. In any case if you use the bundle install –without production, you will get an error using sqlite3 which can be solved with either Hendie’s or my solution.
