Dear Maintainers, after pulling revision 5448704355e03a97d2838e1ba30272db335f0dbb I have built inkscape according to https://inkscape.org/develop/getting-started/ Trying to manage extensions (Extensions -> Manage Extensions) I receive the following error message: There has been a problem creating the python environment: Return Code: 3: b'' b'The path =python3 (from --python==python3) does not exist\n' args: ['/usr/bin/virtualenv', '-p=python3', '/home/xx/.config/inkscape/extensions'] Indeed the call is syntactically wrong. Instead of '-p=python3' the option '-p python3' ### without equal sign should be used. As far as I understand, the problem seems to exist in inkscape/share/extensions/extension-manager-bootstrap.py:69 call('virtualenv', TARGET_DIR, p='python3') which then in inkex/command.py:to_args() is evaluated to the wrong sytnax. According to the (very good) comments in to_args() :Keyword Arguments: * *name* (``str``) -- Becomes ``--name="val"`` ... * *n* (``str``) -- Becomes ``-n=val`` ... it should become ``-n val``. I do not know whether a change would result in problems using other programs that want -n=val. Which should that be?
