I am trying to install dreamerv3 via pip

Check this (openai/gym#3202) Many options solved the problem.

requirements.py should have wheel==0.38.4 added to it in order to fix this if we must stick with gym 0.19.0 (which is to my understanding not maintained by OpenAI anymore)

This fixed it for me: pip install setuptools==66 wheel==0.38.4
And pip install -U "jax[cuda12_pip]" -f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html
Then the instructions in the README work.
