Re: from django.utils.six.moves import range, ImportError: cannot import name 'range'

[Melvyn Sopacua]

Is it possible you create your virtual environments
with global site-packages?
>From what I'm seeing this is caused primarily by
version mismatches of the six library and using
OS site-packages with virtualenv would certainly
do it as setuptools and pip both use six.

The difference with 1.10/1.11 I cannot explain
though.

Re: from django.utils.six.moves import range, ImportError: cannot import name 'range'

[Derek Zeng]

Hi Melvyn,

Renaming MIDDELWARE_CLASSES doesn't help either.

These are the requirements I have:

django==1.10.5
djangorestframework
markdown
django-filter
django-jinja
pytest
factory_boy

fabric3
pytest-django

feedparser==5.2.1
pytz
PyYAML
lxml
requests

django-extensions
Werkzeug

django-cors-headers
psycopg2
django_compressor
django-libsass
livereload

---

I tried to comment out the code you quoted. But that has no effects.

Re: from django.utils.six.moves import range, ImportError: cannot import name 'range'

[Melvyn Sopacua]

Rename MIDDLEWARE_CLASSES to
MIDDLEWARE in settings to see if that changes anything.
If not, remove one by one (except static). There are some changes to
the static files middleware [1], but I can't really relate that to
your error.

Is there anything in your project requirements that also uses six?

There's no diff between 1.10.x and 1.11.x on six.py, but this code
looks like a possible root cause:

# Here's some real nastiness: Another "instance" of the six module might
# be floating around. Therefore, we can't use isinstance() to check for
# the six meta path importer, since the other six instance will have
# inserted an importer with different class.
if (type(importer).__name__ == "_SixMetaPathImporter" and
importer.name == __name__):
del sys.meta_path[i]
break

If I turn off debug mode, it gives me 500 error and showing the same stack
trace in the console.

I also tried 1.11.4, still the same error.

Re: from django.utils.six.moves import range, ImportError: cannot import name 'range'

Could you turn off DEBUG and check what the problem is then?
The reason is that I want to make sure we're not judging the side
effect of *rendering* the exception.

it's the same in either versions of python. the output was captured when i

Re: from django.utils.six.moves import range, ImportError: cannot import name 'range'

It is a project I developed in ubuntu and currently running on a ubuntu 
server. I just bought a new mac mini, so I would like to develop on mac.

I have isolated the problem to the django version.
 
When I use django==1.10.7, this does not happen.
When I use django==1.11a1 this happens. 

This is the full stack trace:

Re: from django.utils.six.moves import range, ImportError: cannot import name 'range'

Hi,

Today I tried to install my django project on a new mac computer. I used
virutalenv to setup the packages.

After I start the app by running './mange.py runserver' and access the home
page I got the error

from django.utils.six.moves import range, ImportError: cannot import name
> 'range'


Really not sure why it has this weird error. I'm using python 3.6.2

Any help is appreciated!


Is the referenced error coming from code that you wrote?

There's a comma at the end of the import line, which may cause that error.

Also make sure that you've installed Django within your virtualenv. If it
is, then also make sure you have six installed (although Django should have
done that already).
