I have created a virtualenv and want to install python v.3.8.7 using either pip or easy_install tools without affecting the python version installed on the system which Python 2.7.
I tried using:
<code>pip install python3 --upgrade #in the virtual environment
</code>
<code>pip install python3 --upgrade #in the virtual environment
</code>
pip install python3 --upgrade #in the virtual environment
But the error states that I need to upgrade Python 2.8 which is the main Python used on my machine (not the virtualenv)

How to install Python 3.8.7 in a virtual environment using either pip or easy_install ?

I think the python3.8.7 is not installed in your system? I mean the python file install in their website, not the pip install in your env.
