CLI fails due to missing colorclass dependency (v3.1.141 regression)

[jbeich]

Regressed by b3b93f45fc16

Expected behaviour:

Running CLI via flexget_vanilla.py (not installed) or flexget (after install) without arguments shows usage string without any errors. Other CLI commands also work without showing colorclass errors.

Actual behaviour:

Every CLI command fails due to colorclass not specified in either requirements.in or requirements.txt e.g.,

$ python3.8 flexget_vanilla.py --help

Oops, let those slip through. They are fixed now though. Thanks for the report!
