How do I change the local project version of pyenv?

Create a directory for your python project and change directory to it.

$ mkdir demo_env
$ cd demo_env

Before changing the local python version.

$ pyenv versions
  system
  2.7.15
* 3.8.5 (set by /home/trainer/demo_env/.python-version)
  3.8-dev

Change the local version of python for specific python project.

$ pyenv local 3.8-dev

Check the python version being used again.

$ pyenv versions
  system
  2.7.15
  3.8.5
* 3.8-dev (set by /home/trainer/demo_env/.python-version)
