`cv2` is not a package that can be installed directly using pip. It is a package that comes with OpenCV, a popular computer vision library. To install OpenCV and `cv2`, you can use the following command:

pip install opencv-python-headless

This command will install a headless version of OpenCV, which does not require a GUI. If you need the GUI version of OpenCV, you can use:

pip install opencv-python

After installing OpenCV, you can import `cv2` module in your Python code.
