Installation in Vagrant

If you are running a Vagrant based VM (Virtualbox) and have mounted folders in which you wish to intialize a virtualenv, you need to add the --always-copy flag, like so:

virtualenv venv --always-copy

Otherwise, you'll end up with an OSError: [Errno 71] blah blah blah symlink



If you forked, you will have a remote branch named origin which points to the version of your repository as it currently exists on the GitHub servers. Note, however, that your fork is disconnected from Epic's version of the repository -- we need to remedy that.

If you have not already done so, define a new remote branch pointing to Epic's UnrealEngine repo:

git remote add upstream
