Docker build fails

[compilenix]

Hey there, I have trouble building the current master branch (cc2604ac554c4a98be2e0ee15496441dd9a72b67) container image. The error message says it can't find the package cachetools in the required version (5.2.0).

Steps to reproduce

cd /tmp
git clone https://github.com/pkpio/fitbit-googlefit
cd fitbit-googlefit
docker build .

Output

# cd /tmp
# git clone https://github.com/pkpio/fitbit-googlefit
