installing paramiko and cryptography fails in linux while using virtual environment for python

Question

I am able to install paramiko and cyrptography when outside the virtual environment.

But when I try:

source env/bin/activate 
pip3 install cryptography

I get the following error:

Preparing metadata (pyproject.toml) ... error
  error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.
