出现错误 ModuleNotFoundError：没有名为“rest_framework_sso”的模块

Question

I am following https://pypi.org/project/djangorestframework-sso/ tutorial for sso authentication in django, In first step they added 'rest_framework_sso' in INSTALLED_APPSin settings.py without installing any such liberary. When I tried to do the same I got:

ModuleNotFoundError: No module named 'rest_framework_sso'

Then I tried pip/pip3 install 'rest_framework_sso' but I got:

ERROR: Could not find a version that satisfies the requirement rest_framework_sso (from versions: none)
ERROR: No matching distribution found for rest_framework_sso

Then I installed django rest framework but it is stil not working.

I want to know why is it not working and how can I solve this, I didn't found anything that can help me related to this.

Answer 1

(For the wiki-aspect, I'll write down a proper answer in case someone comes by the question later)

We have to differentiate between two things here: The name of the package on Pypi, which is what you have to use with pip , and the name of the python module that is provided in that package.

For the django rest framework SSO package, the Pypi package name currently is djangorestframework-sso , so that has to be used with pip

pip install djangorestframework-sso

However, the python module that this allows you to use is named rest_framework_sso , so when adding this to the INSTALLED_APPS or using it in any other way in python, you need to use this name, as demonstrated in the documentation:

from rest_framework_sso.views import obtain_session_token
# go on to use obtain_session_token

If you wonder, there is a questions about why this is the case
