import moment from 'moment-timezone'; import 'moment/min/locales'; not working

[rendomnet]

Environment

{
"moment": "2.29.4",
"momentTz": "0.5.43",
"date": "Sat Oct 28 2023 16:45:48 GMT+0600 (East Kazakhstan Time)",
"intlZone": "Asia/Almaty"
}

Issue description

import moment from 'moment-timezone';
import 'moment/min/locales';

the locales do not load. But if I use

import moment from 'moment';
import 'moment/min/locales';

then it works

Usually situations like this are caused by accidentally having 2 different copies of moment somewhere in the dependency tree. See the "npm" and/or "yarn" sections at #982 (comment) for tips to verify if that's the problem (and how to fix it).

@gilmoreorless
I have only this

    "moment": "^2.29.4",
    "moment-timezone": "^0.5.43",

What's specified in package.json is only part of the story. As #982 (comment) explains, what matters is how the dependencies are actually installed in node_modules. moment-timezone could be depending on a version of moment that's different from the one you've specified.

This is something I'm hoping to solve by moving moment to be a peer dependency of moment-timezone (#1039 (comment)).

I've completely removed the 'node_modules' directory and reinstalled it, but the issue still persists. Do I need to have "moment" for 'moment-timezone' to have the necessary locale files? Are they compatible?

[gilmoreorless]

If there's a lockfile like package-lock.json or yarn.lock that's storing the duplicate versions, removing node_modules won't fix the problem. I've already linked to better explanations of how to diagnose and fix this.
