ERROR: Cannot install extractcode[full]==21.7.23 because these package versions have conflicting dependencies.

The conflict is caused by:
    extractcode[full] 21.7.23 depends on extractcode-7z>=16.5.210525; extra == "full"
    The user requested (constraint) extractcode-7z==16.5.210531

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
