Notes

The package tidycovid19 was only installable from inside R remotes::install_github("joachim-gassen/tidycovid19")

To try

Does pip succees in your local environment?

pip install git+git:https://github.com/haozhu233/kableExtra@master

As pip failed to install and it could be because of my local environment it is worth to try to put it in the environment.yml as

dependencies:
   - pip:
     - git+git:https://github.com/haozhu233/kableExtra.git
