How do I resolve issues with Python virtual environments?

I'm having trouble activating my Python virtual environment. What should I do?

First, make sure you're in the correct directory where your virtual environment is located. You can activate it using the command source venv/bin/activate on macOS/Linux or venv\Scripts\activate on Windows.

I tried that, but I get an error saying the file doesn't exist.

Check if the virtual environment was created successfully. You should see a folder named 'venv' in your project directory. If it's not there, you may need to create it again using python -m venv venv.

I see the folder now. What if I still can't activate it?

Ensure that your terminal or command prompt has the correct permissions. You might also want to check if your Python installation is correctly set up.
