            Pycairo vs. cairocffi vs. Qahirah
            Asked 2022-Mar-16 at 11:43

            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".

            Mimicking the C API closely means that functions take simple arguments. As an example, the move_to function/method looks like this:

            Don't exactly know what went wrong but I got it fixed by:

            1. completly removing my virtual environment
            2. creating a new one.
            3. installing packages with pip install -r requirements.txt --no-cache-dir

            the --no-cache-dir was really important adding.

            check the cairocffi package has an issue or not and even it is correctly installed or not. And try to install it again, so maybe these issues will be solved. 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

            cairo is a C library. cairocffi is one Python interface to it. You have installed cairocffi, but not cairo. Be sure to install cairo as well with your system's usual package manager, as described in the cairocffi docs:

            It seems like you'll need to do a bit of downloading on your own.

            From the error message, you at least need to download the headers for freetype and png (The links are indications only. Please read further into them before deciding whether they match your needs and whether you trust them).
