I am facing the erro above, I can imagine that is related to some kind of path definition that is not properly defined, but have no idea where to begin.
My Env
windows 10 home
Currently using CONDA, version 4.9.2, installed on my "C" driver.
# conda environments:
#
base C:\ProgramData\Anaconda3
pranos39 C:\ProgramData\Anaconda3\envs\pranos39
agen37 C:\Users\ennio\.conda\envs\agen37
agen39 C:\Users\ennio\.conda\envs\agen39
baseold C:\Users\ennio\.conda\envs\baseold
python38 C:\Users\ennio\.conda\envs\python38
* d:\conda_env\py38 (this is the one I activate)
And the editor is vscode 1.51.1 version. using pylint, and it is pointing to the python env above.
I have the driver "D" where is the conda env being used. And also, where is the source code.
D:\Linguagem\mooc\code\polls38
Tutorial being used
since it is the first time using the virtual env to build a django app, I decide to use the tutorial available to test:
Using the exemplo, as it is.

To create de app "polls" I had to use the command:
django-admin startapp polls polls38/polls (firstly I created the folder).
I was facing an error, when running "python manage.py runserver".
ERROR: module no found "polls".
I solved the problem, by adding at the manage.py the path to the app, as bellow (i do not believe that its the best solution)
def main():
"""Run administrative tasks."""
sys.path.append('D:/linguagem/mooc/code/polls38/polls38')
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'polls38.settings')
try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise ImportError(
"Couldn't import Django. Are you sure it's installed and "
"available on your PYTHONPATH environment variable? Did you "
"forget to activate a virtual environment?"
) from exc
execute_from_command_line(sys.argv)
I was able to run the first and second part of the tutorial.
In the third part, after improving the polls/views, another problem showed-up.
And if I try to run, the follwing error occurs:
when I issue the command "python manage.py runserver"
(d:\conda_env\py38) D:\Linguagem\mooc\code\polls38>python manage.py runserver
D:\Linguagem\mooc\code\polls38
