Can't install tensorflow

Can somebody help me solve and understand the error below? I am running on a Mac with the latest OS release

install_tensorflow()
Error: could not find a Python environment for /usr/local/bin/python3.8

tf$constant("Hellow Tensorflow")
Error: Installation of TensorFlow not found.

Python environments searched for 'tensorflow' package:
/usr/local/Cellar/python@3.8/3.8.5/Frameworks/Python.framework/Versions/3.8/bin/python3.8

You can install TensorFlow using the install_tensorflow() function.

Have you installed tensor-flow on conda?
Or try using py_install("tensroflow").

That doesn't work. I think that there is some connection between R and Python that is missing and that I am not familiar with:

library(reticulate)
py_install("tensorflow")
Error: could not find a Python environment for /usr/local/bin/python3.8

Have you verified that python works on your computer?
Have you downloaded miniconda and set the path?
Try to install python again.
Then try to configure it from tools-global options.

My path is a windows one.
