Hey, i'd like to change some lines in lib file but don't have permission to do it, so i run:
chmod g+w /usr/local/lib/python3.6/dist-packages/xlrd/compdoc.py
but got an error that
chmod: changing permissions of ‘/usr/local/lib/python3.6/dist-packages/xlrd/compdoc.py’: Operation not permitted
how can i do that? thanks
