How to use Jedi's `Project` feature?

Question

So I'm playing around with jedi. I would like jedi to print all references of a specific variable in a directory. To test this out, I wrote something like:

./project/__init__.py:

./project/a.py:

x = 5; x = 7

./src/__main__.py:

from jedi import *

p = Project('./project')

code = """from project.a import x
x"""

s = Script(code, path='./project/b.py', project=p)

res = s.get_references(2, 0)

print(res)

And I'm running it with python3 -m src. However, it doesn't seem to work.

I get

[<Name full_name='project.a.x', description='module x'>, <Name full_name='b.x', description='x'>]

In other words, it seems to think that x is a module, and doesn't find the two uses of x in a.py. Thank you! Any ideas how to accomplish this? Unfortunately, all of the examples only use Scripts without Projects.
