Getting requirements to build wheel ... error >>> Error compiling Cython file: spacy/vocab.pxd:28:10: Variables cannot be declared with 'cpdef'. Use 'cdef' instead. about cso-classifier

Hi,

Have you tried to use python 3.7? or on a brand new environment?

I am sorry, but this is a new issue that I have never encountered before.

Hi Angelo. Thank you for the quick reply. I will try and come back to you.
In the meantime I discovered this: https://cython.readthedocs.io/en/latest/src/changes.html
in the "related changes:" section :
Variables can no longer be declared with cpdef. Patch by David Woods. (Github issue #887)

Hello @angelosalatino - I tried with python 3.7.17 on Mac, VSCode, ZSh, and a new venv -- I have the same error.
