[New-bugs-announce] [issue41754] Webbrowser Module Cannot Find xdg-settings on OSX

[Tony DiLoreto]

New submission from Tony DiLoreto <tony.diloreto at gmail.com>:

The following code does not work on many OSX installations of Python via homebrew:

>>> import webbrowser
>>> webbrowser.open("http://www.google.com")

And throws the following error stack trace:

  File "/usr/local/opt/python at 3.8/Frameworks/Python.framework/Versions/3.8/lib/python3.8/webbrowser.py", line 26, in register
    register_standard_browsers()
  File "/usr/local/opt/python at 3.8/Frameworks/Python.framework/Versions/3.8/lib/python3.8/webbrowser.py", line 551, in register_standard_browsers
    raw_result = subprocess.check_output(cmd, stderr=subprocess.DEVNULL)
  File "/usr/local/opt/python at 3.8/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 411, in check_output
    return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
  File "/usr/local/opt/python at 3.8/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 489, in run
    with Popen(*popenargs, **kwargs) as process:
  File "/usr/local/opt/python at 3.8/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 854, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
  File "/usr/local/opt/python at 3.8/Frameworks/Python.framework/Versions/3.8/lib/python3.8/subprocess.py", line 1702, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
NotADirectoryError: [Errno 20] Not a directory: 'xdg-settings'



The only workaround right now is to modify webbrowser.py via the instructions here: https://github.com/jupyter/notebook/issues/3746#issuecomment-489259515.

Thank you for resolving.
