Pycharm cant open manage.py task

Question

In one of my projects , I cannot open manage task console. It works for other projects but not for this one. It worked before, but it stopped recently. I tried using old versions of the project, but its still broken. I get this error:

    Failed to get real commands on module "Visdjango": python process died with code 1: Traceback (most recent call last):

Answer 1

update your _utils.py in YOUR_PYCHARM_INSTALLATION_DIR\helpers\pycharm\django_manage_commands_provider\_parser\_utils.py

and changes the code in line 20:

assert isinstance(opt.choices, list), "Choices should be list"

with

assert isinstance(opt.choices, (list, tuple)), "Choices should be list or tuple"

Answer 2

Install version 4.5.3 RC

If you are using a virtual environment, make sure your project interpreter (settings > Project:... > Project Interpreter) points to the python executable in it (e.g., my_virtual_env/bin/python3.4).

If you are using a virtual machine, you also need to have your project interpreter setting point to the python version under your virtual environment under your virtual machine. If you are using Vagrant this is easy, as when you try to add a new interpreter PyCharm lets you select Vagrant, and then browse the VM file system to point to the file you needed.

Answer 3

It looks like a bug in the new manage.py tasks integration of PyCharm 4.5. Please report this issue to the PyCharm's issue tracker.
