Create a Python virtual environment

Hello! This is Ponta, a Shiba Inu. I'm getting used to the Mac gradually. I'm trying to install Django today, but when I tried to do it suddenly, the owner scolded me. First, create a virtual environment for Python. It's unreasonable because the text procedure that the owner skipped cleaning up didn't mention the virtual environment.

Ponta@dog # python -m venv venv_dog

You now have a virtual environment. venv is a magic trick for creating a virtual environment, the second is the directory of the virtual environment. Let's see what happens to the directories in the virtual environment.

Ponta@dog # tree -L 3
.
└── venv_dog
    ├── bin
    │   ├── Activate.ps1
    │   ├── activate
    │   ├── activate.csh
    │   ├── activate.fish
    │   ├── easy_install
    │   ├── easy_install-3.8
    │   ├── pip
    │   ├── pip3
    │   ├── pip3.8
    │   ├── python -> /Library/Frameworks/Python.framework/Versions/3.8/bin/python
    │   └── python3 -> python
    ├── include
    ├── lib
    │   └── python3.8
    └── pyvenv.cfg

5 directories, 12 files

Now it's time to enter the Python virtual environment!

Ponta@dog # cd venv_dog/bin 
Ponta@bin # source activate
(venv_dog) Ponta@bin #

Oh, the command line has changed! Owner!

(venv_dog) Ponta@bin # python -V
Python 3.8.5
(venv_dog) Ponta@bin #

One that worked!

Install Django

Finally, the owner told me to install Django. Install with pip.

(venv_dog) Ponta@bin # pip install django

It seems to have worked, but I'll check it with pip just in case.

(venv_dog) Ponta@bin # pip list
Package    Version
---------- -------
asgiref    3.2.10
Django     3.1
pip        20.2.2
pytz       2020.1
setuptools 47.1.0
sqlparse   0.3.1
(venv_dog) Ponta@bin #

It looks like you're in Django! The version is 3.1. You can also check the version by the following method.

(venv_dog) Ponta@bin # python -m django --version
3.1
(venv_dog) Ponta@bin #

That's it. See ya! Bye bye!
