Syntax error "syntax error, unexpected end-of-input, expecting keyword_end (SyntaxError)"

It seems that you have a bunch of describes that never have ends keywords, starting with describe "when email format is invalid" do until describe "when email address is already taken" do

Put an end on those guys and you're probably done =)

Do you perhaps have one too many here?

 describe "when name is too long" do
     before { @user.name = "a" * 51 }
     it { should_not be_valid }
 end
 end
