failed to build flask-graphql graphql-server-core promise about mariana-trench

It seems that wheel package is not installed, maybe try pip install wheel first?

There're some dependencies issues in fb-app. As a workaround, I just install those packages manually BEFORE running pip install mariana-trench.

Thanks! After some attempts, I can install successfully like this, avoiding version conflicts. This issue is just to tell developers that it may be possible to update dependencies to newer versions.

$ python3 -m venv mariana-trench
$ source mariana-trench/bin/activate
$ python3 -m pip install mariana-trench "graphene<3"
$ deactivate
