I see what the issue is. You are following instructions that were writtenpost deleted by a lazy person. Here's how to fix it:
Instructions you are following
sudo apt-get update
sudo apt-get install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev \
pkg-config libgl1-mesa-dev libgles2-mesa-dev \
python-setuptools libgstreamer1.0-dev git-core \
gstreamer1.0-plugins-{bad,base,good,ugly} \
gstreamer1.0-{omx,alsa} python-dev libmtdev-dev \

See those slashes at the end of every line? That means "I'm too lazy to install everything one or a few at a time, I want to type the entire thing on one line and press enter and be done with it but there's too many packages to fit on a single line."
So, those 6 lines that start with sude apt-get install
need to all be typed together as one line, just remove all the slashes. Or, alternativelyposter, type sudo apt-get install
withdidn't see there was a few ofsliding bar in the packages (the order doesn't matter).
Try that and post back.original code pasted
