Great thanks gang. I'll look into Just's Skia stuff.

Hey there trying to install Drawbot as a module on a Ubuntu server running Python 3.8.10 and getting the following error. This is a dumb question, but is Drawbot Mac OS X only?

Traceback (most recent call last):
  File "<string>", line 1, in <module>

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: '/usr/bin/sw_vers'

It does actually work fine from within DrawBot itself. I have been using this since the end of Jan and haven't had an issue.

Thanks for that @justvanrossum. I am using the Python modules todoist, requests, and urllib3 to visualise my todo list in Drawbot.

After reading this I kind of resolved to manually downloading each module and have them sit in the same folder as my Drawbot script. This is so tedious especially for updating modules.

But then I realised that I could still set up my virtualenv, pip install my modules, their dependencies and then in my Drawbot script include the path to the site-packages.

import sys
sys.path.insert(0, "/Users/maartenidema/t_venv/lib/python3.6/site-packages")

On a quick initial test, this seems to work. I wonder if there will be module conflicts with Python versions going forward.

I often set up a different virtual environment for different Python-based scripting ideas that I run in the terminal. I will do this using virtualenv and pip install the needed modules.

So my question is can I select a Python virtualenv from within the Drawbot app or a script that I'm running in Drawbot?

I have tried adding a shebang at the top of the script pointing to the virtualenv's python. I have also tried something like this:

activate_this_file = "/Users/maartenidema/Desktop/t_venv/bin/activate_this.py"
execfile(activate_this_file, dict(__file__=activate_this_file))

I feel like I am really overlooking something quite simple.
