Steps to correctly install and configure Django's development environment

How to correctly install Django and configure the development environment

Django is an advanced web application framework developed using the Python language. It provides a wealth of tools and functions that can Help developers quickly build complex web applications. This article will introduce how to correctly install Django and configure the development environment, as well as provide relevant code examples.

Step One: Install Python and pip
To start using Django, you first need to install Python and pip (Python package manager). You can go to the official Python website (https://www.python.org) to download the latest version of Python and install it. During the installation process, make sure to check the "Add Python to PATH" option so that you can use Python and pip commands directly from the command line.

After the installation is complete, open the command line window and run the following command to check whether Python and pip are installed correctly:

python --version
pip --version

If the output shows the version information of Python and pip, the installation is successful.

Step 2: Install virtualenv
In order to isolate different projects and environments, it is recommended to use virtualenv to create an independent Python environment. Run the following command on the command line to install virtualenv:

pip install virtualenv

After the installation is complete, use the following command to create a new virtual environment:

virtualenv myenv

where myenv is the name of the virtual environment, which can be Modify according to your own needs. After creation, use the following command on the command line to activate the virtual environment:

source myenv/bin/activate  # 在Linux和Mac OS上
myenvScriptsctivate    # 在Windows上

After activating the virtual environment, all Python packages will be installed in the virtual environment without affecting the global Python environment. You can use the pip list command to view the packages installed in the current virtual environment.

Step 3: Install Django
In the activated virtual environment, run the following command to install Django:

pip install Django

After the installation is complete, you can use the following command to verify whether Django is successfully installed :

django-admin --version

If the output displays the Django version information, the installation is successful.

Step 4: Create a Django project
In the virtual environment, run the following command to create a new Django project:

django-admin startproject myproject

where myproject is the name of the project, you can customize it according to your own Modifications are required. After the creation is completed, you can use the following command to verify whether the project is configured correctly:

cd myproject
python manage.py runserver

After running the above command, if the command line outputs information similar to the following, the project has been successfully created and run:

Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Open the browser and visit http://127.0.0.1:8000/. If you can see Django's default welcome page normally, it means the project configuration is correct.

At this point, we have completed the installation of Django and the configuration of the development environment. Next, you can start developing your own web application according to your own needs.

Summary:
This article introduces how to correctly install Django and configure the development environment in four simple steps. First, you need to install Python and pip, then use virtualenv to create an independent Python environment, then install Django through pip, and finally create a new Django project and verify whether the configuration is correct. I hope this article will be helpful to developers who are new to Django.
