The editor can only run on python 2.7. You shouldn't start the script as root (sudo -H).
edit: also, consider upgrading you pip since it looks pretty old.
pip2 install --upgrade pip
edit2: It looks like pip is still trying to install an invalid version of numpy on python 2.7. Just change this line on the installer script and it will work.
