python - How to pip install "lru"?

Question

I am trying to use a python deep learning module keras-audio to train from audio files (python 3.8.6, MacOS 10.14.6). However, after installing that module and trying to run an example I get the following error

Traceback (most recent call last):
  File "demo/cifar10_train.py", line 1, in <module>
    from keras_audio.library.cifar10 import Cifar10AudioClassifier
  File "/Users/user/keras-audio/keras-audio/keras_audio/library/cifar10.py", line 2, in <module>
    from lru import LRU
ModuleNotFoundError: No module named 'lru'

so I tried to install that package with

pip install lru

which created the following error:

Collecting lru
