QUESTION
I want to create and rasterize vector graphics in Python. I suspect that Pycairo or cairocffi (edit: or Qahirah) are a great choice. (If not, comments are welcome.)
What are the practical differences between the two?
Specifically, the Pycairo documentation says:
If Pycairo is not what you need, have a look at cairocffi, which is an API compatible package using cffi or Qahirah, which is using ctypes and provides a more "pythonic" API with less focus on matching the cairo C API.
But this raises some questions: In what cases may Pycairo be "not what you need", whereas cairocffi is? In what way are cffi/Qahirah/ctypes better than whatever Pycairo does instead? In what ways is Pycairo not "pythonic"? If cairocffi is better than Pycairo, why is Pycairo more popular, does it have advantages?
Edit: A comma might be missing after "cffi" in the quote above. In that case, it's not about "Pycairo vs. cairocffi", but about "Pycairo vs. cairocffi vs. Qahirah".

Also check your database. like when you write python manage.py make migrations , if your database is not created as superuser, so it will give you errors if your packages are already satisfied then try to uninstall it

Sorry I know there seems to be a lot about this topic. But I do not see a real resolution?

Install cairocffi
You can use cairocffi like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
