Handling Mini-Conda with PyEnv

About

We sometimes need to install packages thru some sources such as conda-forge and PyPi. Therefore, we need to handle both environments, Conda (Mini-Conda) and the other virtual python on same environment. This is kind of headache because of confliction. But I found that there is a way to install mini conda on the pyenv environment. It means that we can use virtual-env and conda on the same environment.

Install Mini-Conda

pyenv install miniconda3-4.7.12
pyenv global miniconda3-4.7.12
#conda init bash
#source ~/.bashrc
pyenv activate miniconda3-4.7.12
conda create -n base-env python=3.10 -y
conda activate base-env

Install Mamba

conda install -n base-env -c conda-forge mamba -y
conda install -c conda-forge mamba -y

Clone and Activate

conda create --name petsc-env --clone base-env
conda activate petsc-env

Install Package

mamba install -c conda-forge petsc4py
