Como instalar o Django no Windows

This document will guide you through installing Python 3.8 and Django on Windows. It also provides instructions for setting up a virtual environment, which makes it easier to work on Python projects. This is meant as a beginner’s guide for users working on Django projects and does not reflect how Django should be installed when developing patches for Django itself.

The steps in this guide have been tested with Windows 10. In other versions, the steps would be similar. You will need to be familiar with using the Windows command prompt.

Instalando Python

Django is a Python web framework, thus requiring Python to be installed on your machine. At the time of writing, Python 3.8 is the latest version.

To install Python on your machine go to https://python.org/downloads/. The website should offer you a download button for the latest Python version. Download the executable installer and run it. Check the boxes next to “Install launcher for all users (recommended)” then click “Install Now”.

Depois da instalação, abra a linha comando e verifique se a versão do Python é a mesma que a versão instalada executando:

...\> py --version

Sobre o pip

pip is a package manager for Python and is included by default with the Python installer. It helps to install and uninstall Python packages (such as Django!). For the rest of the installation, we’ll use pip to install Python packages from the command line.

Setting up a virtual environment

It is best practice to provide a dedicated environment for each Django project you create. There are many options to manage environments and packages within the Python ecosystem, some of which are recommended in the Python documentation. Python itself comes with venv for managing environments which we will use for this guide.

To create a virtual environment for your project, open a new command prompt, navigate to the folder where you want to create your project and then enter the following:

...\> py -m venv project-name

This will create a folder called ‘project-name’ if it does not already exist and setup the virtual environment. To activate the environment, run:

...\> project-name\Scripts\activate.bat

The virtual environment will be activated and you’ll see “(project-name)” next to the command prompt to designate that. Each time you start a new command prompt, you’ll need to activate the environment again.

Instalando Django

O Django pode ser facilmente instalado dentro de seu ambiente virtual usando o pip.

Na linha de comando, assegure-se que seu ambiente virtual esteja ativo, e execute o seguinte comando:

...\> py -m pip install Django

Isso irá baixar e instalar a última versão do Django.

Depois que a instalação for concluída, você pode verificar sua instalação do Django executando django-admin --version na linha de comando.

Armadilhas comuns

• Se o django-admin somente mostra o texto de ajuda não importando quais argumentos lhe é dado, provavelmente tem um problema com a associação do arquivo no windows. Verifique se existe mais de uma variável de ambiente definida para rodar os scripts Python no PATH. Isso normalmente ocorre quando existe mais de uma versão de Python instalada.

• If you are connecting to the internet behind a proxy, there might be problems in running the command py -m pip install Django. Set the environment variables for proxy configuration in the command prompt as follows:

  ...\> set http_proxy=http://username:password@proxyserver:proxyport
  ...\> set https_proxy=https://username:password@proxyserver:proxyport
