--help throws TypeError: Cannot read property 'replace' of undefined

[springcomp]

I’m learning to author Yeoman Generators and would like to use TypeScript.
I stumble across the following issue which has been closed. #1717

Here is a repro case:
https://github.com/springcomp/yeoman-custom-generator

The generator and its subcommand work (just prompting and logging for now).
However displaying help fails:

yo sample --help
yo sample:router --help

With the following message:

Error sample --help 
Cannot read property 'replace' of undefined

I cannot figure out how to troubleshoot this.

https://github.com/springcomp/yeoman-custom-generator no longer exists. @springcomp is this still something you want to investigate? We have a maintenance reboot (#1779) and we can walk you through it. 🙂

@JoshuaKGoldberg thanks for the feedback.

I’ll be retrying to create a repro and come back to this issue.

@JoshuaKGoldberg we can close that issue now. Sorry for the confusion.

As part of your reboot, are you planning to support ESM instead of CommonJS ?

Glad it worked out!

support ESM instead of CommonJS

Good question. It really depends on how much work it is.
In theory, now that Node.js supports require() of ESM (https://joyeecheung.github.io/blog/2024/03/18/require-esm-in-node-js -> https://nodejs.org/api/modules.html#loading-ecmascript-modules-using-require), issues like SBoudrias/Inquirer.js#1194 around using ESM in CJS should magically go away in the latest versions of Node.js. So you might find it all works out of the box now! ✨

But if not, I'd say that's a feature request issue to be filed on https://github.com/yeoman/yo. yeoman/yo#787 is related but looks to me more about source code running as ESM.
