To Reproduce Steps to reproduce the behavior: 1 - create folder ~/projects 2 - cd into folder ~/projects and clone git repo 3 - run pip install -r requirements.txt ( no capital -R as described in readme as this doesn't work ) 4 - open firewall port using: sudo ufw allow 8000/tcp 5 - start yapo using command: python manage.py runserver 127.0.0.1:8000

error received: AttributeError: module 'memcache' has no attribute 'Client'

Expected behavior start of the yapo webserver

Screenshots

Python version: Python 3.9.7 running under Ubuntu VERSION="18.04.6 LTS (Bionic Beaver)"

Additional context tried to start with and without sudo rights ( so as std user or as root ). Error is the same

Apologies for the late answer.

YAPO does not use memcached by default. The error is caused by something not working in your installation as this hasn't been reported earlier.

You can remove the reference to memcached in YAPO/settings.py

Change lines 30 to 42 from:

if not DEBUG or TEST_MEMCACHE:
    CACHES = {
        'default': {
            'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
            'LOCATION': '127.0.0.1:11211',
        }
    }
else:
    CACHES = {
        'default': {
            'BACKEND': 'django.core.cache.backends.dummy.DummyCache',
        }
    }

to:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.dummy.DummyCache',
    }
}

Remember to observe the required Python indentation (this project uses tabs)
