[SOLVED] How can I create a copy of a virtualenv in pyenv?

Issue

I used pyenv to create a virtualenv and activate it,

pyenv virtualenv myenv
pyenv activate myenv

then proceeded to perform a complicated and time-consuming installation of various Python packages in that virtual environment. Now I'd like to clone or duplicate or copy this virtualenv somehow, so that I can deactivate myenv and leave it untouched while I experiment with variations. Basically, I'm looking for something like

pyenv virtualenv-copy myenv myenv-copy

which I would use in a sequence such as, for example,

pyenv deactivate
pyenv virtualenv-copy myenv myenv-copy
pyenv activate myenv-copy

but nothing like pyenv virtualenv-copy seems to exist. What is the recommended approach for achieving this?

Solution

When you create an environment in pyenv, it stores it in the directory $(pyenv root)/versions/ Where pyenv root is the installation area of pyenv. On Ubuntu 20.04 for me, it is /home/username/.pyenv.

Now you can copy the env you want from the versions and give it a new name to have an exact copy of that env. So you can do

$ cp -R (pyenv root)/versions/old_env $(pyenv root)/versions/new_env

This will create a copy of old_env with the name new_env.
