ERROR: Cannot install extractcode[full]==31.0.0 because these package versions have conflicting dependencies.

### Description

> Getting the following error while setting up dev env for scancode-toolkit.

### Error

ERROR: Cannot install extractcode[full]==31.0.0 because these package versions have conflicting dependencies.

The conflict is caused by:
extractcode[full] 31.0.0 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
