You should start your Virtual Environment   how to do it   first with terminal cd into the directory containing manage py  then type  source  lt myvenv gt  bin activate replace  with you Virtual Environment name  without angular brackets   Another issue can that your root directory and venv mis-match  The structure should be something like this    -website        facebook        manage py        myvenv        some other files   That is your virtual environment and manage py should be in the same folder  Solution to that is to restart the project  If you are facing this error you must haven t coded anything yet  so restart

What am I wondering is though the django is installed to the container it may not be in the host machine where you are running the command  Then how will the command run  So since no above solutions worked for me   I found out the running container and get into the running container using docker exec -it  lt container gt  bash  then ran the command inside docker container  As we have the volumed container the changes done will also reflect locally  What ever command is to be run can be run inside the running container

I had the exact same error  but then I later found out that I forget to activate the conda environment which had django and other required packages installed    Solution  Create a conda or virtual environment with django installed   and activate it before you use the command     python manage py migrate

User · Answer

The solution is straightforward  the exception from manage py is because when running the command with python  Django is unable to predict the exact python version  say you may have 3 6  3 5  3 8 and maybe just one of this versions pip module was used to install Django to resolve this either use     manage py  enter code here  lt command gt    or using the exact python version x x  stands   pythonx x manage py  lt command gt    else the use of virtual environments can come in handy because its relates any pip django module easily to python version   create env with pyenv or virtualenv activate  e g in virtualenv    virtualenv env  run using python manage py command

I had same problem and could solve it  It is related to the version of Django you ve installed  some of them are not supported by python 2 7  If you have installed Django with pip  it means that you are installing the latest version of that which probably is not supported in python 2 7  You can get more information about it here  I would suggest to python 3 or specify the version of Django during installing  which is 1 11 for python 2 7
