molecule 3.2.x will not execute

[jamesla]

But when using molecule 3.2.x

Works fine with < 3.1.5

Do you have rich installed? How did you install molecule?

[apatard]

hm. weird. the dependency tree is molecule -> enrich -> rich. molecule and enrich are installed, so rich should be installed too. What might be the problem would be rich being too old (so without rich.ansi) but enrich is depending correctly on rich >= 9.2.0 to avoid that...

[ssbarnea]

That appears to be a user error, better to use the forum for that. I bet that running "pip check" would indicate that you have some conflicts, like using an outdated version of rich.

[t2d]

The latest update with pip3 install --upgrade molecule did break my installation as well.

pip3 check
enrich 1.2.3 has requirement rich>=9.2, but you have rich 9.1.0.

Shouldn't pip solve this dependency itself?

[zeitounator]

I just tested the above and got the same issue (wrong version rich-7.1.0), until I upgraded pip to latest version (20.2.4 => 20.3.1) and ran the upgrade once more which successfully installed rich-9.3.0 as a requirement.

In case there is anything to do to enhance that (but I doubt) here is a full output of my install. Note: pip is linked to pip3 in my environment
