Environment data

Actual behaviour

Go to definition doesn’t work. I see infinity loader

Steps to reproduce:

Install python from pyenv (pyenv install 3.5.5 && pyenv shell 3.5.5)
Generate simple Django project, create env: python -mvenv env && source env/bin/activate
Try to create forms / models / views etc
From views or forms import model
Try to remove any py file from project:

[Error - 2:38:04 AM] One or more errors occurred. (failed to parse file file:///Users/ali/Projects/aliev/infinity-server/topic/views.py)

after that go to definition stops working

@aliev Version 0.1.75 of the language server was released yesterday. Could you do the following and update the language server to see if it solves your problem?
