@jo Yes, right now I'm working like that,
but I would try to avoid this solution in particular,
since I consider it as not Pythonic and "proper"

I'm looking for a way to install site packages for a new DrawBot.
(I was trying to install for example PageBot or Letterror's coverage)

When I was following the tutorial from PageBot's github (https://github.com/PageBot/PageBot/blob/master/INSTALL.md) It didn't work at all.

this code:

import site

print('Found site at %s' % site.__file__)
packages = site.getsitepackages()
for p in packages:
    print(' - %s' % p)

throws error:

Found site at /Applications/DrawBot.app/Contents/Resources/site.pyc
Traceback (most recent call last):
  File "<untitled>", line 4, in <module>
AttributeError: module 'site' has no attribute 'getsitepackages'

even If I'm trying to change the name of the site.pyc (I'm tring to follow the PageBot tutorial)

import sys
print(sys.path)

prints out

['/Users/--USER--NAME--',
'/Applications/DrawBot.app/Contents/Resources/lib/python36.zip',
'/Applications/DrawBot.app/Contents/Resources/lib/python3.6',
'/Applications/DrawBot.app/Contents/Resources/lib/python3.6/lib-dynload',
'/Applications/DrawBot.app/Contents/Resources/lib/python3.6/site-packages.zip',
'/Applications/DrawBot.app/Contents/Resources/lib/python3.6/site-packages']

so it doesn't care about my python3 site-package folder (/usr/local/lib/python3.6/site-packages/)

Delayed, but still: thanks guys !!!

how to draw glyph of a UFO file in DrawBot outside RoboFont?
So far I came up with this solution, but I don't know what to do next:

from fontParts.world import *

basepath = os.path.dirname(__file__)
filepath = os.path.abspath(os.path.join(basepath, "..", "..", "UFOS/typeface-regular.ufo"))

f = OpenFont(filepath)
for g in f:
    newPage(1000,1000)
    p = g.getPen()
    # I don't know what should I put here

command drawGlyph(g) doesn't work, and I imagine, that it should work only inside of RoboFont.

Thanks for the help in advance
