I am using an M1 mac and I am using a conda environment with python 3.8.8.

I tried to update with 'conda update python' but 3.8.8 is the latest version I can get and it is running on Rosetta 2.

I would like to install the latest 3.9.x for BigSur (so it can run natively) to the conda env (or any env).

I tried to download the python 3.9.4 universal version installer but I do not know how to put it in an virtual environment.

Thanks!

Virtualenvs are interpreter-specific – you set up a virtualenv that uses a given interpreter version.

If you've installed Python 3.9.4 from somewhere, you can then use python3.9 -m venv some_venv to create a virtualenv that uses that interpreter. (Assuming, of course, that that python3.9 is on the path and is indeed the correct interpreter.)

(You can also python3.9 -m pip install virtualenv to install the virtualenv package, which is faster than the stock venv.)

conda is a package manager unto its own, and its environments are not to be confused with regular Python virtualenvs.

  • Thanks - it works- however another problem arise- I encourtered errors when install pandas under virtualenv with python 3.9.4. - but is there any way to have python 3.9.4 under conda? – Tao Apr 22 '21 at 12:27

I installed miniforge by

brew install --cask miniforge

and created a virtual env using conda and I was able to install pandas with python 3.9.1

Here's my log
