I am using Django 1.4.5 and have just installed django-extensions, in a virtualenv. I am using Python 2.7.1. When I type:
./manage.py shell_plus --notebook
I get the error:
Traceback (most recent call last):
File "./manage.py", line 10, in <module>

ImportError: No module named IPython.frontend.html.notebook
Without the --notebook option it works fine. Also, ipython notebook works fine too.
Can anyone suggest what might be going wrong?
thanks!
I solved this by using a new virtualenv, and making sure I had installed iPython in it, i.e:
pip install tornado
pip install pyzmq
pip install ipython
./manage.py shell_plus --notebook
In addition to what user [https://stackoverflow.com/users/905720/racing-tadpole](Racing Tadpole) said above, I also had to install jinja2.
pip install jinja2
A way to test what is missing to have django shell_plus on ipython notebook is trying to execute ipython notebook alone. This way I could detect all missing libraries, like jinja2.
ipython notebook
If this works, your chances are high that shell_plus --notebook will also work.

I have added django_extensions in my settings also,
GRAPH_MODELS = {

}
My requirements.ts looks like following:
Django==1.11.12

django-cors-headers==2.2.0
drfdocs==0.0.11
mysql-python==1.2.5

django-allauth==0.35.0
nltk==3.2.5
django-extensions==2.0.7

I am on Windows 10. How do I resolve this error? Do I need to add anything in my Windows path?Or for Django rest I need other library (https://github.com/chibisov/drf-extensions)
dot.exe is a graphviz executable, which is not found in the search paths.
Have you installed graphviz and its dependencies?
If yes, are they in the search path of windows?

I have read multiple SO posts about this but their solutions dont seem to apply to me. Please note:
1) I have already activated the new virtualenv before running the command.
2) I did not create the new virtualenv using sudo. I just did the following to create it:
virtualenv name-of-the-new-virtualenv
What could I be missing?
When using bash, the version of python being resolved in the PATH can be seen at any time by using which python.
You can also check the location of your sourced virtualenv by viewing the VIRTUAL_ENV environment variable (e.g. echo $VIRTUAL_ENV).
In this case, the issue was that the virtualenv directory had been moved after being created, so the PATH environment variable wasn't getting populated with the virtualenv's correct bin directory upon sourcing. One solution for moving a virtualenv is to make it "relocatable", which is explained in this answer.
Virtualenvs can be activated by sourcing the activate script:
source /path/to/my/venv/bin/activate
When any virtualenv has been sourced, it can be deactivated by using the deactivate function:
deactivate
When i run command pip install django, on go daddy it gives me the following error:
I tried to copy django packages manually into the site-packages of go daddy. I copied it from my local machine. I removed all of them.(I don't know if there is something remaining or not. But i have checked it again) Can you please help with this?
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

sudo apt-get install python3
I just started to try and install/run Django on my cmd prompt and faced this issue although environment variables are set up for Django.
Besides getting a solution, can someone help me understand the root cause of the error below?

In python based project it is always good to create Virtual Environment and then run your django program .
pip install virtualenvwrapper-win
mkvirtualenv test
workon test
this will activate your virtual environment
Now install django
pip install django
After django installation complets
run
django-admin --version
Hope this helps.
On windows, go where you want to create your project, and call from there the django-admin.exe:
path\to\django-admin.exe startproject project_name
Its not a clean solution but worked for me.

The command I'm using is pip install awscli
The problem is about permisson. The installer are trying to write in a folder that doesnt have permission.
try sudo pip install awscli
It looks like it is trying to uninstall six-1.4.1. I had the same issue. Telling pip to ignore installed package should work.
sudo pip install --ignore-installed awscli
sudo pip install --upgrade --user awscli
--upgrade : tells pip to upgrade any requirements that are already installed
