Module 'frontera.contrib.backends.memory' doesn't define any object named 'FIFO'

[Rockyzsu]

Frist time to use frontera, after install frontera and option in https://frontera.readthedocs.io/en/latest/topics/installation.html#options

then run the example under requests/link_followers.py.
But it come with error :

raise NameError("Module '%s' doesn't define any object named '%s'" % (module, name))

NameError: Module 'frontera.contrib.backends.memory' doesn't define any object named 'FIFO'

how to fix it or i am missing something ?

my best guess is the example was already outdated, 1f1f4a1

I think u should directly go to single mode for trying or testing.

thx @liho00
So link_followers.py is not the single mode ?
This link https://frontera.readthedocs.io/en/latest/topics/quick-start-single.html
is the real single mode with scrapy ?

Do you have the latest demo code ?
