ImportError : cannot import name 'ugettext_lazy'

Question

I'm trying to install suit, I entered this command : pip install https://github.com/darklow/django-suit/tarball/v2 and wrote this code :

from suit.apps import DjangoSuitConfig
class SuitConfig(DjangoSuitConfig) :
    layout = 'horizontal'

And added it :

INSTALLED_APPS = [
    'products.apps.SuitConfig',
     .....]

But when I added this last code I had this error :

InvalidTemplateLibrary: Invalid template library specified. ImportError raised when trying to load 'suit.templatetags.suit_menu': cannot import name 'ugettext_lazy' from 'django.utils.translation' (C:\Users\hp\environments\env3\lib\site-packages\django\utils\translation_init_.py)

note : django 4.01

Answer 1

Was just about to ask the version but the note (django 4.01) helped. 'ugettext_lazy' seems to be used by the app you are trying to use as well.

'ugettext_lazy' has been deprecated for django 3+ so you won’t be able to use that with a django version >= 3. https://code.djangoproject.com/ticket/30165

Answer 2

I also got the same issue while using django-hitcount

views.py

from hitcount.views import HitCountDetailView

class PostDetailView(HitCountDetailView):
model = Post
template_name = 'blog/post.html'
slug_field = "slug"
count_hit = True

settings.py

INSTALLED_APPS = [
'hitcount',
 .....]

One answer is ugettext_lazy has been removed in Django 4.0 57. Please use gettext_lazy instead ""

from django.utils.translation import gettext_lazy as _

I put this line of code in the views.py, and got the same error.

Answer 3

I strongly recommend to downgrade Django from "4.x.x" to "3.x.x" to solve your errors:

pip install django==3.*

Because Django 4.x.x is very new so some packages don't catch up with Django 4.x.x. So, if you keep using Django 4.x.x, you will get the same or similar errors in the near future then you will spend a lot of time to solve these errors because of Django 4.x.x.

Actually, I got the same or similar errors when using "django-graphql-jwt", "graphene-django" and so on. Then, for some packages, I could solve such errors but for some packages, I could solve but new other errors occurred then, I couldn't solve these new other errors.

Finally, I noticed I spent a lot of time to solve such errors because of Django 4.x.x. So again, I strongly recommend to downgrade Django from "4.x.x" to "3.x.x" to solve your errors:

pip install django==3.*

Answer 4

I have solved the problem by installing the django==3.2 instead of the latest version of Django. But I`ll still check for the pypi update for the usage in the latest version of Django.
