Answer 1

If your code is formatted like this:
describe "edit" do
let(:user) { FactoryGirl.create(:user) }
before do
sign_in user
visit edit_user_path(user)
describe "page" do
it { should have_content("Update your profile") }
it { should have_title("Edit user") }
it { should have_link('change', href: 'http://gravatar.com/emails') }
end
I can see that it is probably broken without reading any of your code.
Are all your code blocks properly closed? Does not look so!

Answer 2

In addition to the unclosed blocks that phoet pointed out, which are causing your "undefined method describe" errors, you're getting errors in /app/views/users/index.html.erb line 5. The error is undefined method `each' for nil:NilClass which means there's a variable on that line that you're doing variable.each with, but you're either not setting that variable or when you're setting it, it's getting set to nil.
In general, the way for you to successfully get through this is to read the error messages and try to fix what they're complaining about. If you search for each error message individually, you'll find stack overflow questions about the specific issue that will help you.
