Setting Up a Virtual Environment (venv) for Your Project

Steps to Create a Virtual Environment and Install Dependencies

1. Open your terminal (Command Prompt, PowerShell, or any terminal emulator).

2. Navigate to your project directory where your requirements.txt file is located:

   cd path/to/your/project
   

3. Create a Virtual Environment Run the following command to create a virtual environment named .venv:

   python -m venv .venv
   

4. Activate the Virtual Environment

   4.1 Windows:

    .venv\Scripts\activate
   

   4.2 On macOS and Linux:

    source .venv/bin/activate
   

5. Install Dependencies With the virtual environment activated, install the dependencies listed in your requirements.txt file:

   pip install -r requirements.txt
   

6. Deactivate the Virtual Environment Once you are done working in the virtual environment, you can deactivate it by running:

   deactivate
   

Additional Tips Checking Installed Packages: To see a list of installed packages in your virtual environment, use: pip list

Freezing Dependencies: If you add new packages and want to update your requirements.txt file, run: pip freeze > requirements.txt
