Start from scratch: How to install the Django framework using commands

Django is a popular Python web framework that provides developers with a convenient and fast way to Build high-quality web applications. Before we start using Django, we first need to install the framework in our development environment. This article will provide detailed steps and specific code examples to help you easily start installing the Django framework using commands.

Step 1: Install Python and PIP

Before installing Django, we need to make sure that Python and PIP have been successfully installed on our computer. Python is the foundation of the Django framework, and PIP is Python's package management tool for installing and managing Python packages.

We can check whether Python and PIP have been installed by running the following command:

python --version
pip --version

If Python and PIP are not installed, you can go to the Python official website to download and install them.

Step 2: Create a virtual environment

The virtual environment is an independent Python running environment that can avoid package conflicts between different projects. We recommend creating a virtual environment before installing Django.

Use the following command to create a virtual environment in the project folder:

python -m venv myenv

Where, myenv is the name of the virtual environment, you can modify it according to your needs.

Step 3: Activate the virtual environment

After creating the virtual environment, you need to activate the virtual environment to use Python and PIP in it.

On Windows, use the following command to activate the virtual environment:

myenvScriptsctivate

On Mac/Linux, use the following command to activate the virtual environment:

source myenv/bin/activate

Step 4: Install Django

After activating the virtual environment, we can use the PIP command to install Django.

pip install Django

This will automatically download and install the latest version of Django from the Python Package Index (PyPI).

Step 5: Verify installation

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

django-admin --version

This will display the version number of Django, indicating a successful installation .

Step 6: Create a Django project

Now that we have successfully installed the Django framework, we can start creating a new Django project.

Use the following command to create a project in the current folder:

django-admin startproject myproject

Where, myproject is the name of the project, you can modify it according to your needs.

Step 7: Run the project

After the project is created, enter the project folder:

cd myproject

Then, use the following command to run the Django project:

python manage.py runserver

This will start a local development server, listening on http://127.0.0.1:8000/ by default.

Now, you can visit http://127.0.0.1:8000/ in the browser and see Django's default welcome page, which means the project runs successfully.

Summary:

Through the above steps and code examples, we successfully installed the Django framework and created a new Django project. Now you are ready to start using Django to build powerful web applications.

It should be noted that in actual development, we will also use other Django extensions and tools to improve development efficiency and feature richness. I hope this article will be helpful for you to learn the Django framework, and I wish you a happy use!
