I was having a similar problem, and I believe the accepted answer doesn't reflect the question since it's been edited. I do believe my solution solves the stated problem as it is right now.

The original question was how to create a virtualenv in selected python version explicitly, for which Somil's answer is correct.

However, for those who wish to create a virtualenv using a python version installed by pyenv, here is my answer.

I was trying to create a virtualenv using Python 3.6.9, having 3.10.7 installed system-wide. I had no luck using the system installed virtualenv. I tried virtualenv -p ~/.pyenv/versions/<version>/bin/python env, and although it creates the folders and scripts, it presented errors regarding wheel packages.

What worked was installing virtualenv from the pyenv installed version and using it to create the env.

  1. Install the Python version you want:
$ pyenv install <version>
  1. Select that version to run on your current shell
$ pyenv shell <version>
  1. Install virtualenv using pip from that version
$ pip3 install virtualenv
  1. Use the installed virtualenv to create the env.
$ virtualenv -p python3 env

If you're using pyenv, I would recommend building a pyenv controlled virualenv (make sure pyenv-virtualenv is installed first) 

$ pyenv virtualenv 2.7 <your new env>

Which you can then switch to this virtualenv using pyenv

$ pyenv local <your new env>

or 

$ pyenv shell <your new env>
