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 test it without altering it.
django-admin startproject mysite
cd mysite
python manage.py runserver
File "manage.py", line 14
) from exc
^
SyntaxError: invalid syntax
I'm getting a SyntaxError on a file that was generated by the system itself. And I seem unable to find anyone else who has gone through the same issue.
I'll add some data of my setup in case it may be of use
$ vpython --version
Python 2.7.12
$ pip --version
pip 9.0.1 from /home/frank/.local/lib/python2.7/site-packages (python 2.7)
$ python -m django --version

try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise ImportError(

"available on your PYTHONPATH environment variable? Did you "
"forget to activate a virtual environment?"
) from exc

Make sure which python version you connect the django with (Make sure to activate the virtual env if you are using any).
When you install django using just
pip install django
then you have to run
python manage.py startapp <yourApp name>
else if you have used:
pip3 install django
then you have to run
python3 manage.py startapp <yourapp name>
Refer:
You can try with python3 manage.py runserver.
It works for me.
You should activate your virtual environment.
In terminal, source env/bin/activate. Depending on your shell, something like (env) should now be a part of the prompt.
And now runserver should work. No need to delete exc part!
Just activate your virtual environment.
For running Python version 3, you need to use python3 instead of python.
The final command will be:
python3 manage.py runserver
I was experiencing the same but this was solved by running with specific python 3.6 as below:
python3.6 manage.py runserver
Its a simple solution actually one i just ran into. Did you activate your virtual environment?
my terminal screenshot
It's best to create a virtual environment and run your Django code inside this virtual environment, this helps in not changing your existing environments. Here are the basic steps to start with the virtual environment and Django.
Create a new Directory and cd into it.
mkdir test , cd test
Install and Create a Virtual environment.
python3 -m pip install virtualenv virtualenv venv -p python3
Activate Virtual Environment: source venv/bin/activate
Install Django: pip install django
Start a new project: django-admin startproject myproject
cd to your project and Run Project:
cd myproject,
python manage.py runserver
You can see your project here: http://127.0.0.1:8000/
After testing with precise instructions (using python2 or python3 instead of just "python") I've constated that no matter what the tutorial says, this works ONLY with python3.
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
I solved same situation.
INSTALLED VERSION
python 3.6, django 2.1
SITUATION
I installed Node.js in Windows 10. After python manage.py runserver caused error.
ERROR
File "manage.py", line 14
) from exc
^
SyntaxError: invalid syntax
REASON
My python path changed to python-2.7 from python-3.6. (3.6 is correct in my PC.)
SOLUTION
Fix python path.
The following could be the possible reasons,
1. The virtual environment is not enabled
2. The virtual environment is enabled but the python version is different
To create virtual environment
$ virtualenv --python=python3 venv
To activate the virtual environment
$ source venv/bin/activate
You must activate virtual environment where you have installed django.
Then run this command
- python manage.py runserver
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.
Pipenv documentation:
https://pipenv.kennethreitz.org/
Activate your virtual environment then try collecting static files, that should work.
$ source venv/bin/activate
$ python manage.py collectstatic
You should start your Virtual Environment,
How to do it?
First with terminal cd into the directory containing manage.py
Then type $source <myvenv>/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.
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
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
Version: 1.11a1
Summary: A high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Home-page: https://www.djangoproject.com/

Requires: pytz
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🎉
We have to create a virtual environment inside the project, not outside the project..
Then it will solve..
I landed on the same exact exception because I forgot to activate the virtual environment.
I was also getting the same error.
Then I went back to the folder where the environment folder is there and I forgot to activate a Virtual environment so only I was getting this error.
Go to that folder and activate the virtual environment.
$ source env/bin/activate
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
Same issue occurred to me,But what I did was,
Just Replaced:
python manage.py runserver
with
python3 manage.py runserver
in the terminal(macOsX). Because I am using Python version 3.x
I encountered the same error when using pipenv. The issue was caused by not accessing Django correctly from within the virtual environment.
The correct steps using pipenv:
Activate virtual environment: pipenv shell
Install Django: pipenv install django
Create a project: django-admin startproject myproject
Navigate into project folder: cd myproject
Start Django with pipenv: pipenv run python manage.py runserver
Note: Pipenv will use the correct python version and pip within the virtual environment.
It seems you have more than one version of Python on your computer.
Try and remove one and leave the only version you used to develop your application.
If need be, you can upgrade your version, but ensure you have only one version of Python on your computer.
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 <container> 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
For future readers,
I too had the same issue. Turns out installing Python directly from website as well as having another version from Anaconda caused this issue. I had to uninstall Python2.7 and only keep anaconda as the sole distribution.
Have you entered the virtual environment for django? Run python -m venv myvenv if you have not yet installed.
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).
I solved this problem to uninstall the multiple version of Python.
Check Django Official Documentation for Python compatibility.
"Python compatibility
Django 2.1 supports Python 3.5, 3.6, and 3.7. Django 2.0 is the last version to support Python 3.4."

If removing "from exc" from second last line of this code will generate another error due to multiple versions of Python.

Any idea??
Probably, pip installs packages into dist-packages directory, which is not included into PYTHONPATH environment variable. You have a couple of solutions:
Create and configure virtualenv for your project, before using pip. This is the most Pythonic way
Try to install Django using built-in pip module:
python -m pip install django
This command should install packages into site-packages directory.
You may also add dist-packages to your PYTHONPATH. This question should help you: How to globally modify the default PYTHONPATH (sys.path)?
This error shows that Django is not installed. Installing Django should solve the problem.
In my case, Django was there in my virtualenv but while using gunicorn I was getting this error then later I realized gunicorn was dealing with my globally install python environment not my virtual environment installing Django on my global python env simply solved my issue.
pip install django
I got this error when using
python manage.py runserver #python version 3 was being used
Solved the problem by using:
python2 manage.py runserver #python version 2
I had the similar error for other modules which are already installed, executing same command as superuser:
sudo pip3 install -r requirements.txt
solved my issue.
You need to close the other active virtual environment in your machine if you're using virtualenv, and make sure django installed. Go to python3 interpreter and run this:
>>>from django import get_version
>>>get_version()
make sure it show you this '2.1.4'
For Mac users; If you've previously downloaded and installed python3, just running python via the terminal shell defaults to using the pre-installed python v2, which will not recognise your installation of django (unless you install it via the python2 module) and you'll probably get an error when you check the version:
$ python
>>> from django import get_version
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named django
Try starting python using:
$ python3
Then try:
>>> from django import get_version
>>> get_version()
You should get the output:
'2.0.3'
I had given the dependency in requirements.txt as Django==2.0.7. So after activating the virtual environment, if you are receiving the message, try installing the requirements:
pip install -r requirements.txt
I also faced the same problem. i was using python 3.7 and installed django 2.2. So i degraded my python to 3.6 and installed django 2.2, and without having a virtualenv.
I got the same issue today. doing pip3 install django or pip3 install -r requirements.txt solved it.
python3 manage.py migrate solved my problem
I was getting this error while running:
python manage.py migrate
I changed to python3 ...
Try updating the Django.
I was getting the same issue because I had an older version of Django installed. I installed the latest version of Django instead and it fixed my issue.
I faced same issue with you when try to setup Apache work with Django.
Issue solve after add Pythonpath to Apache2.conf as bellow:
WSGIPythonPath/opt/djangoprojects/myproject:opt/anaconda3/lib/python3.6/site-packages
I installed Python3 before.
This error shows you didn't install Django. Installing Django should solve the problem.
Once you do, you can just check the path of "django" using:
>>> sys.path
For MacOs,I was getting the same issue while using import django.I deactivated conda and again activated django virtual environment by conda.Then made sure the python version is correct,in my case it was python 3.8.5.Then navigate to the project's directory and run the required python script.
My Django version is 3.1.5
Unistall/Install
Confirm that you're running from virtualenv of you have installed the app to venv.
If you made sure that it has been installed and still shows mdule not found, uninstall and install again.
Maybe your env not running after you shut down your computer. Just need to pipenv shell to launch again the virtual environment.
Then u can see this one the terminal
Launching subshell in virtual environment...
. /Users/.../.local/share/virtualenvs/little-lemon-O3-M0emD/bin/activate
and, type python3 manage.py runserver to start your django server and work normally.
My Question is pretty Simple.
Whenever I use virtualenv environment in my Django project it gives the following error when executed this command
python manage.py runserver
File "manage.py", line 8, in
from django.core.management import execute_from_command_line
ImportError: No module named django.core.management
But when i use root and give the same command it seems to work perfectly. Why does this Happen? I am in the virtualenv so it means i am the root person by default.How can i fix this error?
I had seen many forums but couldn't find related to mine.
This happens because you have installed django in the system-wide Python interpreter; possibly by doing something like sudo pip install django.
Once you create a virtual environment and activate it - it contains no packages. The concept of a virtual environment is that it allows you to install Python packages without affecting the global Python installation.
So once you activate a virtual environment, you have to install packages in that virtual environment; so you should pip install django (note: without sudo) once you activate the virtual environment; like this:
$ virtualenv sample_env
...
$ source sample_env/bin/activate
(sample_env) $ pip install django
A virtual environment is a virtual environment for Python; it does not control what the user is that is logged into the system.
Finally, as a general rule - you should not be using root for development purposes as doing so can easily compromise your system.
Yup i have same error while running Django. I also have enabled virtual environment. But I was still getting error.
Solution to this problem is using this command to install any python package
python -m pip install django
This will definitely solve your problem. As it solved mine.
So i have been playing around with python (2.7.x) and django framework on my ubuntu (12.04). The way i setup django based project is by using virtualenv
Which i did it like this
** FROM TERMINAL **
1. sudo apt-get install python-setuptools
2. sudo easy_install virtualenv
Then i continue setting up my directory for my django project by using this command:
virtualenv --no-site-packages project-name
Soon after that, i activated my virtualenv:
source project-name/bin/activate
Then i continue with the Django framework installation using this:
sudo easy_install Django
and verify that Django framework is installed within my virtualenv by checking there is a file called django-admin.py under project-name/bin/ directory (which is exists).
However, the second time i tried to create another django-project (completely different one) following the same exact step as above, I don't have django-admin.py installed in the correct directory. It's get installed to /usr/lib/python...
And when i tried to run the app i get this message:
Traceback (most recent call last):
File "manage.py", line 8, in <module>
from django.core.management import execute_from_command_line
ImportError: No module named django.core.management
Does anyone know why is this happening?
Thanks.
* EDITED PART *
responding to sachitad's answer
i get the following message when i executed his/her suggestion
(project-name)blah#blah:~/Documents/python/project-name$ easy_install django
error: can't create or remove files in install directory
The following error occurred while trying to add or remove files in the
installation directory:
[Errno 13] Permission denied: '/home/blah/Documents/python/project-name/lib/python2.7/site-packages/test-easy-install-3775.write-test'
The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:
/home/blah/Documents/python/project-name/lib/python2.7/site-packages/
that's why, i initially thought i need to use the sudo command.
Problem:
sudo easy_install Django
Even if you have activated the virtualenv, while installing packages inside virtualenv, never ever use sudo. If you use sudo, it assumes you are installing on the system path(/usr/lib/local/..).
Thus,
easy_install django
OR
pip install django
should work.
As an addition to sachitad answer, I suggest you have a look at virtualenvwrapper which allow you to manage easily you virutal env with commands like :
mkvirtualenv your_project_name // create a virtual environment
workon your_project_name // select this virtual environment
pip install django // will install in this virtualenv
./home/user/path_to_virtual_env_project_/bin/pip install Django
you call pip which not in virtual env.
It seems activate not work.
I get the following error when trying to run Django from the command line.
File manage.py, line 8, in <module>
from django.core.management import execute_from_command_line
ImportError: No module named django.core.management
Any ideas on how to solve this?
It sounds like you do not have django installed. You should check the directory produced by this command:
python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
To see if you have the django packages in there.
If there's no django folder inside of site-packages, then you do not have django installed (at least for that version of python).
It is possible you have more than one version of python installed and django is inside of another version. You can find out all the versions of python if you type python and then press TAB. Here are all the different python's I have.
$python
python python2-config python2.6 python2.7-config pythonw2.5
python-config python2.5 python2.6-config pythonw pythonw2.6
python2 python2.5-config python2.7 pythonw2 pythonw2.7
You can do the above command for each version of python and look inside the site-packages directory of each to see if any of them have django installed. For example:
python2.5 -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
python2.6 -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"
If you happen to find django inside of say python2.6, try your original command with
python2.6 manage.py ...
sudo pip install django --upgrade
did the trick for me.
I got the same error and I fixed it in this manner:
I had to activate my virtual environment using the following command
source python2.7/bin/activate
Most probably in your manage.py the first line starts with !/usr/bin/python which means you are using the system global python rather than the one in your virtual environment.
so replace
/usr/bin/python
with
~/projectpath/venv/bin/python
and you should be good.
well, I faced the same error today after installing virtualenv and django. For me it was that I had used sudo (sudo pip install django) for installing django, and I was trying to run the manage.py runserver without sudo. I just added sudo and it worked. :)
Are you using a Virtual Environment with Virtual Wrapper? Are you on a Mac?
If so try this:
Enter the following into your command line to start up the virtual environment and then work on it
1.)
source virtualenvwrapper.sh
or
source /usr/local/bin/virtualenvwrapper.sh
2.)
workon [environment name]
Note (from a newbie) - do not put brackets around your environment name
I am having the same problem while running the command-
python manage.py startapp < app_name >
but problem with me is that i was running that command out of virtual environment.So just activate your virtual environment first and run the command again -
I experience the same thing and this is what I do.
First my installation of
pip install -r requirements.txt
is not on my active environment. So I did is activate my environment then run again the
pip install -r requirements.txt
The problem occurs when django isn't installed on your computer. You also get this error because the django.core.management module is missing.
To solve this issue we have to install django using pip. Open a command line prompt -> cmd(on windows) and enter the following command:
pip install django
This command will install django on your computer. So consider installing pip first. Here's how to install pip on a Windows machine
Okay so it goes like this:
You have created a virtual environment and django module belongs to that environment only.Since virtualenv isolates itself from everything else,hence you are seeing this.
go through this for further assistance:
http://www.swegler.com/becky/blog/2011/08/27/python-django-mysql-on-windows-7-part-i-getting-started/
1.You can switch to the directory where your virtual environment is stored and then run the django module.
2.Alternatively you can install django globally to your python->site-packages by either running pip or easy_install
Command using pip: pip install django
then do this:
import django print (django.get_version()) (depending on which version of python you use.This for python 3+ series)
and then you can run this: python manage.py runserver and check on your web browser by typing :localhost:8000 and you should see django powered page.
Hope this helps.
In case this is helpful to others... I had this issue because my virtualenv defaulted to python2.7 and I was calling Django using Python3 while using Ubuntu.
to check which python my virtualenv was using:
$ which python3
>> /usr/bin/python3
created new virtualenv with python3 specified (using virtualenv wrapper https://virtualenvwrapper.readthedocs.org/en/latest/):
$ mkvirtualenv --python=/usr/bin/python3 ENV_NAME
the python path should now point to the virtualenv python:
$ which python3
>> /home/user/.virtualenvs/ENV_NAME/bin/python3
This also happens if you change the directory structure of your python project (I did this, and then puzzled over the change in behavior). If you do so, you'll need to change a line in your /bin/activate file. So, say your project was at
/User/me/CodeProjects/coolApp/
and your activate file is at
/User/me/CodeProjects/coolApp/venv/bin/activate
when you set up your project, then you changed your project to
/User/me/CodeProjects/v1-coolApp/
or something. You would then need to open
/User/me/CodeProjects/v1-coolApp/venv/bin/activate
find the line where it says
VIRTUAL_ENV="/User/me/CodeProjects/coolApp"
export VIRTUAL_ENV
and change it to
VIRTUAL_ENV="/User/me/CodeProjects/v1-coolApp"
before reactivating
In my case, I am using Ubuntu. The problem can be that I don't have the permission to write to that folder as a normal user. You can simply add the sudo before your command and it should work perfectly. In my case sudo python manage.py syncdb.
I had the same issue and the reason I was getting this message was because I was doing "manage.py runserver" whereas doing "python manage.py runserver" fixed it.
I had the same problem and following worked good, you should navigate main folder in your project than type:
source bin/activate
My case I used pyCharm 5 on mac. I also had this problem and after running this command my problem was solved
sudo pip install django --upgrade
had the same problem.run command 'python manage.py migrate' as root. works fine with root access (sudo python manage.py migrate )
You can try it like so : python3 manage.py migrate (make sur to be in the src/ directory)
You can also try with pip install -r requirements.txt (make sur you see the requirements.txt file when you type ls after the migrate
If after all it still won't work try pip install django
Hope it helps
I got the same problem trying to use the python manage.py runserver. In my case I just use sudo su. Use the terminal as a root and try it again an it works partially. So I use python manage.py migrate comand and it fix it.
You must choose your Project first before running the server , type this
workon your_project_name
then
python manage.py runserver
It is because of virtual enviornment configuration. You need to work on your virtual enviornmnet of Python. You should try on your command promt with,
workon virtual_enviornment_name
File and Directory ownership conflict will cause issues here. Make sure the ownership of the directories and files under the project are to the current user. (You can change them using the chown command with the -R option.) Try rerunning the command: this solved the problem for me when running through the "First Django App" sample:
python manage.py startapp polls
