I can't figure out a workaround. How can I solve this? ''' pip install cffi ''' Requirement already satisfied: cffi in c:\users\user\pycharmproject\onlineshop\venv\lib\site-packages (1.15.0) Requirement already satisfied: pycparser in c:\users\user\pycharmproject\onlineshop\venv\lib\site-packages (from cffi) (2.19)

CodePudding user response：

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
