TypeError: __new__() got an unexpected keyword argument 'schema'

Root Cause:

coreapi.Field does not have a 'schema' argument in coreapi 2.3.0
It is available only 2.2.4
The django rest framework 3.6.2 that i runnin recommends upgrading to 2.3.0 or above.

    def get_schema_fields(self, view):
        assert coreapi is not None, 'coreapi must be installed to use `get_schema_fields()`'
        assert coreschema is not None, 'coreschema must be installed to use `get_schema_fields()`'
        fields = [
            coreapi.Field(
                name=self.page_query_param,
                required=False,
                location='query',
                schema=coreschema.Integer(
                    title='Page',
                    description=force_text(self.page_query_description)
                )
            )

Sorry for the confusion. But I will close it because this was caused by the coreapi-devin package that got installed and was overriding coreapi. Not sure what caused coreapi-devin to get installed into my evironment
