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

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

How To Reproduce

• run ./configure --dev

System configuration

Ran into the same issue, tried to workaround this bug by changing line 20 in requirements.txt from extractcode-7z>=16.5.210531 to extractcode-7z>=16.5.210525 extractcode-7z>=16.5.210525 but still getting below error message. Happy to help debug the issue if someone can from the ScanCode team can assist me.

Issue seems to be same as #3141

[pombredanne]

@tsteenbe @arnav-mandal1234 are you both running an ARM on Apple?

[pombredanne]

Could you try to install v31.2.6 in the 31 range?

[lumaxis]

@pombredanne I've tried this with 31.2.6 and 32.0.6 and still get the same error as posted above.

[Telshin]

Any progress on this? I still cannot use the latest dev branch.

@Telshin Maybe my workaround described #3626 (comment) will work for you as well.
