🐍 Create Virtual Environment and Use requirements.txt in Django

Want to start a Django project and manage your packages properly? Here’s how to create a virtual environment and use requirements.txt.

🧪 1. Create Virtual Environment with python -m venv

  • Open your terminal
  • Go to your project folder
  • Run the command python -m venv myenv
💡 Note for Mac users: On macOS, use python3 -m venv myenv instead of python. venv created

📌 Why Use a Virtual Environment?

Virtual environments keep your project’s packages isolated. It also:
  • Prevents conflicts between different projects
  • Lets you use different versions of the same package
  • Makes it easier to manage dependencies

🧠 2. Activate the Virtual Environment

  • On Windows: myenv\Scripts\activate
  • On Mac/Linux: source myenv/bin/activate
  • You will see (myenv) at the beginning of the terminal line
venv activated

✅ Final Step

Now that your environment is active, you can install packages like Django using pip. For example: 
pip install django
💡 Note for Mac users: On macOS, use pip3 install django instead of pip.

🔐 Safety Tip

To save your installed packages, use this: 
pip freeze > requirements.txt
requirements This will create a requirements.txt file that lists all dependencies. You can install them later with: 
pip install -r requirements.txt
💡 Mac users: Again, use pip3 install -r requirements.txt if needed. requirements
