Graphene: import graphene not working

[creativesands]

import graphene gives me the following error

Traceback (most recent call last):
  File ".../app.py", line 1, in <module>
    import graphene

Hi,
It seems you are using Graphene 2.0.dev, so you will need the latest package of graphql-core that have ResolveInfo.

You can solve the issue by doing pip install "graphql-core>=2.0.dev"

EDIT: I had a folder called graphql in my path. Changing its name fixed this.

I have the same issue:

Out of interest, is this generally a problem with _any_ Python lib, or just some particular way Graphene is importing the graphql lib?

@leebenson it's a result of how Python find modules: https://docs.python.org/3/tutorial/modules.html#the-module-search-path

I had this issue as well.

My only dependency in requirements.txt was: graphene-django==2.1.0

According to pip freeze, it seems, this has installed graphql-core==3.0.0a0. I downgraded that to pip install "graphql-core<3.0.0a0" and thus got rid of the issue.

Is this a bug with the latest graphene-django package? Is it referring to a 3.0 version of graphql-core prematurely?

[jkimbo]

@mbrochh if you install the latest version of graphene-django (2.4.0) it should resolve graphql-core correctly.
