URIs not supported error

[kamalpnayan]

When i am following the django tutorial with django 1.11.2 and Python 3.6.1 i see the following error. I am using sqlite3 backend.

Performing system checks...

System check identified no issues (0 silenced).

The above exception was the direct cause of the following exception:

Most likely this isn't a bug in Django. A past ​django-users thread suggests it's a Python issue. You're better off getting help there. Perhaps somehow an older versions of sqlite3 is being used? Did you tweak the DATABASES setting? For what it's worth, here are versions on my Python 3.5 install:

>>> import sqlite3
>>> sqlite3.version_info
(2, 6, 0)
>>> sqlite3.sqlite_version_info
(3, 11, 0)

You got this problem because your python was compiled with sqlite < 3.5.0. Checking the versions won't help.
If you are using CentOS 6, don't use python34 from EPEL or rh-python36 from SCL. You can use python from miniconda3 as your base python interpreter. Here is my detailed analysis: ​https://github.com/WqyJh/django_sqlite3_checker/blob/master/python-sqlite3-django-versions.md
