Sorry this took a bit longer – we also pushed an update to preshed, had to fix a few other dependency issues, and then decided to include a bunch of stuff that was originally only going to be shipped with v2.1.x. So spaCy v2.0.12 turned into a much bigger release.

But I just tested installing spaCy on Python 3.7 and it all seems to work fine now 🎉

Similar problem here, it seems it has trouble with Python 3.7 stable.

I tried with pip3 install --pre spacy to use the binary, but still it tries to compile the preshed dependency and it fails with a compile error

preshed/maps.cpp:6643:25: error: no member named 'exc_value' in '_ts'; did you mean 'curexc_value'?

For now I'm installing Conda which is based on Python 3.6, Python 3.7 went stable a few days ago and I guess some native C++ will need adaptations

Same problem here.

Same problem for me

nickyongzhang on 4 Jul 2018

Using python 3.6 instead of 3.7 solved it for me.

Python 3.7 just came out, and while I don't think there's any deep incompatibilities, I think we do need to add specifiers for the new version to our various dependencies.

honnibal on 6 Jul 2018

Same issue for me. It looks like to me that the guilty package is cytools 0.8.2 which does not work with python 3.7 (Collecting cytoolz<0.9,>=0.8 (from thinc<6.11.0,>=6.10.1->spacy)).

Updating it to 0.9.0.1 would solve it.

Same issue here - I've had to downgrade to python 3.6 to be able to use spaCy, but that causes me problems elsewhere :(

Thanks for sharing more details! cytoolz is a dependency of Thinc, so I just updated the version pin on the 6.10.x branch that's compatible with spaCy v2.0.x. See 4ce7854.

Once that's green, we should be able to ship a patch release of Thinc that will make spaCy v2.0.11 installable/compilable on Python 3.7.

But I just tested installing spaCy on Python 3.7 and it all seems to work fine now 🎉

Spacy v2 installs perfectly on 3.7.0 however Spacy v1 does not install. It's the same issue with cytools. We still use Spacy v1 in production because of it's faster for our usage.
