When I run rtv I get the following error:

NotADirectoryError: [Errno 20] Not a directory: 'xdc-settings'

I installed it with homebrew.

Thanks for the bug report. My initial guess is that it has something to do with python 3.7, since that version hasn't really been tested with RTV yet.

[phlind]

Is there maybe an option to run it with Python 3.6 then (when installing with pip or with brew)?

Edit: Nevermind, I just had to use 'pip' instead of 'pip3' of course.

You could also do python3.6 -m pip install to point to a specific version of python. It definitely looks like a bug in python, the web browser library is expecting a "file not found" error, and it doesn't handle a "directory not found" error:

https://github.com/python/cpython/blob/3.7/Lib/webbrowser.py#L532

Interestingly this doesn't appear to be linked to python 3.7 It works for me with python 3.7 on macOS 10.13.4. You might have something else funky on your system that's causing this.

@phlind do you have a file or directory named xdc-settings or xdg-settings in your $PATH?
