Bunch of errors on grunt master with fresh install from Source

[lmuzquiz]

Following the instructions on installing from source

it says:

But running it on a new fresh install gets a bunch of errors:

Anyone has ideas on why is that?

From a quick glance, it looks like you might not set the branch upstream for casper. If you’re not planning on changing it, you should be able to get away with setting the url to the ghost tree

I ran into this too. this ifixed it for me:

cd content/themes/casper
git remote add upstream git@github.com:TryGhost/Casper.git
git pull upstream master
