NameError: name 'pip' is not defined

This error occurs when the pip package installer is not installed or not added to your system's PATH environment variable. To resolve this error, you can try installing pip by following these steps:

1. Download the get-pip.py script from https://bootstrap.pypa.io/get-pip.py
2. Open a command prompt or terminal window and navigate to the directory where you downloaded the get-pip.py script.
3. Run the following command: `python get-pip.py`
4. Once pip is installed, try running your command again.

If pip is already installed but you're still getting the error, you may need to add the path to the pip executable to your system's PATH environment variable.
