II. Installing Python with Pyenv

1.Showing all the versions of Python available

Run the command in the terminal:

2.Installing the desired version of Python

Run the command in the terminal:

III. Creating a virtual environment with Pyenv-virtualenv

1.Creating a virtual environment and assign it to that versio

Run the command in the terminal:

pyenv virtualenv 3.9.8 PROJECTNAME

2.Creating a directory for the project

Run the command in the terminal:

mkdir PROJECTNAME && cd PROJECTNAME/

3.Assign the virtual environment as the local environment for the directory

Run the command in the termina in the directory PROJECTNAME:

pyenv local PROJECTNAME

Now the virtual environment called PROJECTNAME is actived when you are in the PROJECTNAME directory. However, if you want to activate this environment somewhere else, you will enter that directory and run the command in the terminal:

pyenv activate PROJECTNAME

4.Upgrading pip

You can learn how to use Jupyter Notebook here:

V. How to delete virtual environments

1.Showing the list of the existing virtual environments

Run the command in the terminal:

pyenv versions

2.Dlete a virtual environments

If you want to delete PROJECTNAME, run the following command in the terminal:
