How do I troubleshoot issues with my virtual environment?

I'm having trouble activating my 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 venvin\activate on Windows.

I tried that, but I get an error saying 'No such file or directory'.

This usually means that the virtual environment wasn't created properly. You can recreate it by running python -m venv venv in your project directory.

Okay, I recreated it. Now, how do I install packages in this virtual environment?

Once your virtual environment is activated, you can install packages using pip install package_name. Make sure to replace package_name with the actual name of the package you want to install.
