If rdflib has been imported, new_object_graph() raises ImportError

[dswisher]

Sample code:

import pinject
import rdflib

foo = pinject.new_object_graph()

Running this results in the following traceback:

Traceback (most recent call last):

Environment:

• rdflib 4.2.2
• pinject 0.10.2
• python 2.7.13 (MacOS) and 2.7.14 (Amazon Linux)

As a workaround, I'm passing a list of modules to new_object_graph to exclude rdflib, and that seems to be working so far.

Thank you for this awesome library. Other than this one small hiccup, it has been working very well, doing exactly what I would expect it to do.

Can you post a gist example of this? It's not obvious to me from the method signature how to do this.

UPDATE

Answering my own question. This may be different for you but for me the solution was to scope to the "current" module.

pinject.new_object_graph(modules=[sys.modules[__name__]])
