Question

I’m (completely) new to ROR and have got an application to maintain and upgrade. I’ve the source code and am trying to build database using db:migrate rake command. I’ve started using Aptana Studio for the development. When I run dg:migrate I get following errors:

rake db:migrate
(in G:/Projects/.../.../trunk)

I’ve installed hpricot gem also (version 0.8).

What is the remedy for this?

Answer 1

The most significand error is

rake aborted!
no such file to load -- hpricot

You need hpricot. You can install it running the following command on the command line

gem install hpricot
