boltons.ecoutils.pprint error on Python 3.10

[ian-kelling]

Traceback (most recent call last):

    from mail_deduplicate.cli import mdedup

    _real_safe_repr = pprint._safe_repr
AttributeError: module 'pprint' has no attribute '_safe_repr'. Did you mean: 'saferepr'?

looks like it is related to newer python 3.10 than this was developed on

Ah yes. Thanks for the report. I fixed this upstream in click-extra. I need to integrate the later to mail-deduplicate to modernize it a bit, but for the moment I'm focused on finishing what I started on meta-package-manager.

Alternative solutions:

• Downgrade to Python < 3.10
• Have @mahmoud release the development version of boltons, which has a fix for this: Python 3.10 ecoutils error: module pprint has no attribute _safe_repr mahmoud/boltons#294

I think the Python upgrade that leads to this issue happens as part of the dist-upgrade from Ubuntu 20.04 to 22.04, so it'll be becoming very common right about now.

[kdeldycke]

The issue has been fixed with a migration to click-extra. The fix is available in the brand new release of mail-deduplicate 7.0.0.

[danielhatton]

Just to confirm: working for me now.

Thanks @danielhatton for taking the time to check for the fix! 👍
