Windows Installation Guide

You’ll need Python 3.8 (or newer) to run FontBakery. Use the instructions provided at www.python.org to download and install Python 3.8+ on the Windows platform.

Install

pip install fontbakery

Should the above commands give you permission errors, try installing FontBakery into your user directory:

pip install --user fontbakery

Upgrade

pip install --upgrade fontbakery

You then need to add the directory to your environment path. Follow all ways on https://superuser.com/questions/949560/how-do-i-set-system-environment-variables-in-windows-10 until you get to the dialog where you can set variables either system-wide or for your user account. What you need to do is add %LOCALAPPDATA%\Python\PythonYOURPYTHONVERSION\Scripts to your user account’s PATH variable, e.g. %LOCALAPPDATA%\Python\Python38\Scripts for Python 3.8.

If this doesn’t work for you, use py -3 -m fontbakery everywhere you’d use the command fontbakery.
