I\'m following the Django tutorial https://docs.djangoproject.com/es/1.10/intro/tutorial01/
I\'ve created a \"mysite\" dummy project (my very first one) and try to
first with terminal cd into the directory containing manage.py
then type $source
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.
