Hm I just tested installing on my machine and it works.

What terminal command causes the error that you're getting?

My guess is that you're trying to install it somewhere where you need
root permissions, like /opt/ros. If this is the case, you should
install it in ~/ros instead.

Let me know if that doesn't fix it.
