Executing the JSONSchema example

from marshmallow import Schema, fields
from marshmallow_jsonschema import JSONSchema
class UserSchema(Schema):
    username = fields.String()
    age = fields.Integer()
    birthday = fields.Date()
user_schema = UserSchema()
json_schema = JSONSchema()
json_schema.dump(user_schema).data

with marshmallow 3.0.0rc6 installed yields

ModuleNotFoundError: No module named 'marshmallow.compat'

AFAIS the module marshmallow.compat is gone with version 3.0.0. (cf. file finder)

Looks legit! I'll take a look soon unless someone beats me to it!

This library will need to be forward / backward compatible with 2 & 3 for a little bit I think, since the amount of breaking changes in marshmallow 3 are starting to stack up pretty high.

kato-m commented

Any idea how I could work around?

fuhrysteve commented

Fixed by #70

@kato-m if you install from the latest master, you should be all set for marshmallow 3!

Thanks a lot 👍

We are trying to upgrade from 2.19.2 to 3.1.1 and get the same error . Could you please advice how to get around it.

@fuhrysteve This is still not compatible with marshmallow version 3

Still facing the issue.

@RORONOA007 I'm not going to get around to fixing it for awhile unfortunately! But I can review & merge pull requests
