Postgres permission denied on MAC OS X

Question

I was following the ruby on rails tutorial to run with postgres but when I try the \"rake db:create\" I get the following error:

could not connect to server:         


        

Answer 1

I also ran into this problem because I had both the mysql and pg gems active in my Gemfile.

I commented out the mysql gem:

# mysql 

Then ran:

bundle install 

and then:

rake db:migrate 

and it worked like a charm.
