This is macOS Catalina (10.15.7) on a Mac Pro. I have used Root for many years, but am just starting with pyroot.
I just installed Root 6.24.02 from the download page. In the Finder I can run “/Applications/root_v6.24.02/bin/root” – it pops up a Terminal window with a Root prompt, and “new TBrowser” works. So Root itself is properly installed.
The documents imply that pyroot is installed with Root. But it isn’t installed for either the default /usr/bin/python (which is out-of-life 2.7.16), or my python3 from HomeBrew.
I have installed python via HomeBrew: “brew install python”, which puts python 3.9.6 into /usr/local/bin, and I use it a lot (without Root). I can do “pip3 install pyroot” which succeeds, but the symbol pyroot.gRoot is not defined:
Python 3.9.6 (default, Jun 29 2021, 06:20:32) …
>>> import pyroot
[‘doc’, ‘file’, ‘loader’, ‘name’, ‘package’, ‘path’, ‘spec’]
That is useless so I uninstalled that pyroot.
How do I install pyroot into python3 from HomeBrew? Or any other Python 3 on Mac.
The program to which I’m adding Root requires Python 3.
