Same issue here. For what it's worth, I was able to solve it by upgrading from Python 3.6.12 to 3.8.6.

python -m pip install --upgrade pip seems to solve it

Yes, you need to upgrade pip: https://github.com/ijl/orjson#why-cant-i-install-it-from-pypi

I confirm that upgrading pip has solved the issue.
