Installing chatterbot but getting “ERROR: Could not build wheels for spacy which use PEP 517 and cannot be installed directly”

问题

I'm trying to install chatterbot on macOS with

python3 -m pip install chatterbot

and every time I get the same error during the step "Installing build dependencies ... /"

ERROR: Failed building wheel for spacy
Running setup.py clean for spacy
Failed to build spacy
ERROR: Could not build wheels for spacy which use PEP 517 and cannot be installed directly

Can someone please help?

回答1:

You could try python3 -m pip install --no-binary spacy chatterbot, which should tell pip to not build the wheel

Alternately python3 -m pip install --no-use-pep517 chatterbot.

回答2:

Easy, try to run this:

pip install pep517

And then try to install again

python3 -m pip install chatterbot
