Installing Orange Package with older Python Version? I am trying to install an Add-on package from GitHub that contains prototype widgets for Orange Data Mining. I am trying to install it from the GitHub page found here.
I am using the following Terminal code to install this:
git clone http://github.com/biolab/orange3-prototypes.git

Everything then appears to install correctly and the download shows 100%. Then, however, it throws an error and says:

Orange requires Python &gt;= 3.4

I am using Mac OS. Clearly, it is suggesting that I need to use a different version of python to install, however, I already updated my pip install. Any insight into how I can fix this?
The error message shows exactly what you need to do:

Orange requires Python&gt;=3.4

You have to specify a Python&gt;=3.4 version (with orange3 itself installed) while installing orange3-prototypes.
I'm not a Mac user, however, in Windows, Orange3 installer will automatically install a Python 3.4 if there's no compatible Python available.
