I am encountring the following issue. When creating a brand new environment in conda and installing pip , the default version of python3 is switched from 3.7 to 3.8 . Why is this and how can I avoid this? The exact steps are below.

Thank you

conda create -n myenv
conda activate myenv
# python3 --> python3.7.4
conda install pip
# python3 --> python3.8.2
# pip -V --> pip 20.0.2 from /mypath/conda/miniconda3/envs/myenv/lib/python3.8/site-packages/pip (python 3.8)
You never installed python explicitly into your new env, so what you see after conda activate myenv is still the same python from your base env. Now when you do conda install pip, conda recognizes that python is a requirement of pip and therefore downloads and installs python (also check the output of the conda install pip call, where it will list python under the The following NEW packages will be INSTALLED). Since it has no further info, it just grabs the latest one. So your python version is never actually changed, there just never was a python in your venv when you created it.
To fix, explicitly install python into your environment with required version when creating it:
conda create -n myenv python=3.7
