cannot import name 'DocumentNode' from 'graphql' (unknown location)

Hi,

I have solve my own issue but i am reporting it here just in case someone needs it.

The graphql-core==3.1.2 is not compatible with gql==3.0.0a5 (pip install --pre gql[all]) because i want to use the upload file feature.

Using pytest to test my upload file graphql backend, I get the following error when I import the GQL lib

_____________________________________________________ ERROR collecting tests_me.py _____________________________________________________
ImportError while importing test module '/Users/Cyril_Moreau/Perso/Developers/v2/evntz/image-graphql/src/app/image/tests/tests_me.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:

/usr/local/lib/python3.8/site-packages/gql/client.py:5: in <module>
    from graphql import (
**E   ImportError: cannot import name 'DocumentNode' from 'graphql' (unknown location)**

According to the gql setup.py file, the requirements are :
install_requires = [
"graphql-core>=3.1,<3.2",
"yarl>=1.6,<2.0",
]

To fix the issue i had to downgrade to graphql-core==3.1.0 (pip3 install graphql-core==3.1.0)
Now it works.

graphql-core version 3.1.2 should be compatible with gql 3.0.0a5, all the tests are passing for me.

You probably made a manipulation error (the dependencies were maybe not installed correctly), could you please try again with 3.1.2?

You are right,
I tried again with 3.1.2 and it works.
So i dont know what went wrong but it is fixed :(
