Failure to start

[nyvelius]

Hi

I thought I would investigate this project for live streaming. So far I've unfortunately gotten stuck on starting it.

System
macOS Big Sur 11.2.1

Steps to reproduce

[email protected]:bbc/brave.git
pip3 install --user pipenv
pipenv install
brew install libffi
(added to .bash_profile) export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
brew install libnice openssl librsvg libvpx srtp
brew install gstreamer
brew install gst-plugins-base
brew install gst-plugins-good
brew install gst-plugins-bad
brew install gst-plugins-ugly
brew install gst-libav gst-python
pipenv run python3 brave.py

Result

Error processing line 1 of /Users/testuser/.local/share/virtualenvs/brave-rDStWLUb/lib/python3.8/site-packages/ruamel.yaml-0.16.10-py3.8-nspkg.pth:

At the moment i do not have a Big Sur install so i am unable to reproduce, it may be worth using the dockerfile to build and run inside a container.

Would be great to update the instructions for BigSur - spent several hours yesterday trying to install and it's tricky.

pipenv run python3 brave.py

results in

Traceback (most recent call last):

I tried several ways of upgrading to python3 - so I can either import or link pip - or should that be `pip3'

pip3 install pyyaml

installs successfully but does not fix the issue. Recommends I try:

/usr/local/opt/[email protected]/bin/python3.9 -m pip install --upgrade pip

which upgrades pip. But then I get:

fortyfoxes@Black-5 brave % pipenv run python3 brave.py

    import gi

I try installing pip3 install vext and pip3 install vext.gi but it does not help.

I give up.... awaiting updates here for Big Sur
