I installed it via

python -m pip install Cython

I can do:

But then, when I try to install pycocotools by running

python -m pip install git+https://github.com/gautamchitnis/cocoapi.git@cocodataset-master#subdirectory=PythonAPI

I get an error while setuptools is installing the dependencies:

I also tried:

python -m pip install setuptools
python -m pip install --upgrade Cython

but that did not change anything. What am I missing? I’m not using any virtual environments:
