 If you are seeing this error after installing a package locally, then you are missing an [OpenGL](https://en.wikipedia.org/wiki/OpenGL) provider in your system dependencies. This is more likely to happen in headless systems with no graphics (servers, Docker images, etc). To fix it, you must install a provider like [Mesa](https://www.mesa3d.org/) with your system package manager.
