How to solve SyntaxError on autogenerated manage.py?

Question

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

Answer 1

activate env by the Following Command

  source  pathetoYourEnv/bin/activate

then run command

python manage.py runserver

Answer 2

Just activate your virtual environment.

Answer 3

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`<command>

or using the exact python version(x.x) stands:

pythonx.x manage.py <command>

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

Answer 4

Also, the tutorial recommends that a virtual environment is used (see Django documentation: https://docs.djangoproject.com/en/2.0/topics/install/#installing-official-release"). You can do this with pipenv --three. Once you've installed django with pipenv install django and activated your virtual environment with pipenv shell, python will refer to python3 when executing python manage.py runserver.

Answer 5

I had this issue (Mac) and followed the instructions on the below page to install and activate the virtual environment

https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/

$ cd [ top-level-django-project-dir ]

$ python3 -m pip install --user virtualenv

$ python3 -m venv env

$ source env/bin/activate

Once I had installed and activated the virtual env I checked it

$ which python

Then I installed django into the virtual env

$ pip install django

And then I could run my app

$ python3 manage.py runserver

When I got to the next part of the tutorial

$ python manage.py startapp polls

I encountered another error:

     File "manage.py", line 16

   ) from exc
            ^

   SyntaxError: invalid syntax

I removed

from exc

and it then created the polls directory

Answer 6

The django-admin maybe the wrong file.I met the same problem which I did not found on a different computer the same set-up flow.

After comparing two project, I found several difference at manage.py and settings.py, then I realized I created 2.0 django project but run it with python2.

runwhich django-adminin iterm

/Library/Frameworks/Python.framework/Versions/3.6/bin/django-admin

It looks like I got a django-admin in python3 which I didn't know why.So I tried to get the correct django-amin.

pip show django

then I got

Name: Django

In/Library/Python/2.7/site-packages, I found the django-admin

/Library/Python/2.7/site-packages/django/bin/django-admin.py

So I created project again by

/Library/Python/2.7/site-packages/django/bin/django-admin.py startproject myproject

then run

cd myproject
python manage.py runserver

succeeded
