It didn't return a promise before

[jonathanwork]

been getting the same error...

[weshouman]

Workaround I had to downgrade yo to get it working, for example

npm install -g [email protected] generator-generator

[ruieloi]

Hey! Any news about this issue? Is there another way for this to work except to downgrade? Did the method changed?

Thank you

[takashi013]

any help ?

[Aiwwa]

Hello,

I'm also getting same error. Is this the dead end, or there some hopes ?

Thanks.

[Vladyslav317]

Hi, any solutions except for downgrading?

Thanks It helps for mac M1 sonoma 14.4.1 (23E224)

[NgocLe1001]

npm install -g [email protected]

npm install -g [email protected] I resolved by installing this version. maybe you should try.

Check the yeoman-generator version that you use in your generator. This error is present in version 3. If you use JS to write your generator, try 5.10.0 instead, as higher versions only support esmodule

any solutions?

I worked through detailed debugging to understand how to write a generator that works with the latest yeoman yo and generator. At this point none of the Yeoman documentation describes how to build a working generator with the latest version. I'm thinking this project needs to be updated in a similar way. Based on my efforts with my generator, it looks like this project needs to refactored to use import instead of require. Here's a fully functioning generator example that uses the latest version of yeoman and the yeoman generator: https://github.com/yenoh2/generator-hac-tf-module

1. update your package.json adding "type": "module"
2. Since the newer version uses ESM you need to update your generator use imports instead of 'require' in your index.js file. Example: import _ from 'lodash'; import Generator from 'yeoman-generator'; import askName from 'inquirer-npm-name'; import { createRequire } from 'module'; const require = createRequire(import.meta.url); // see full example here: https://github.com/yenoh2/generator-hac-tf-module/blob/master/generators/app/index.js
3. Your export for your extended generator should look like this: export default class extends Generator {

Still getting this - is the project dead? Also, has anyone successfully implemented yenoh2's fix?

[LumiereLodi]

Getting the same error. Any progress so far?

Either the project is dead or we need to get plop using EJS instead of handlebars.

[ralphcorrigan]

I had to roll back, but that worked. Looks like this version is bust (and the lack of response on the thread suggests the project is too)!

[soumilbaldota]

Having the same issue.

I´ve tried with this, it works. Thanks @Aiwwa

Running yo generator fails with

what the ???? is it? I used the latest one 5.10 and still got this issue

👋 Hi all! We're resuming maintenance on Yeoman and picking up old issues like this one. See https://github.com/yeoman/yeoman/issues/1779.

I can reproduce this locally with:

npm i -g yo generator-generator
yo generator

yo generator
? Your generator name generator-yotest
? The name above already exists on npm, choose another? No
Your generator must be inside a folder named generator-yotest
I'll automatically create this folder.
(node:60092) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
(Use `node --trace-deprecation ...` to show where the warning was created)

Just found a `.yo-rc.json` in a parent directory.
Setting the project root at: /Users/josh/repos/yotest
Error generator 

instantiatedGenerator.run is not a function

Digging through, I'm pretty sure the root cause is that generator-generator depends on a very old version of yeoman-generator:

https://github.com/yeoman/generator-generator/blob/f5b3ed87b7a785f85b64ec90de45fbfe88e6e273/package.json#L37

The variable name instantiatedGenerator no longer exists in the latest versions of yeoman-generator. In the Git history, the instantiatedGenerator.run line hasn't existed for a few years. It was refactored away starting in https://github.com/yeoman/generator/pull/1206: https://github.com/yeoman/generator/pull/1206/files#diff-92bbac9a308cd5fcf9db165841f2d90ce981baddcb2b1e26cfff170929af3bd1L941-R979 and continuing through a bunch of subsequent changes to the file.

I tried updating the yeoman-generator dependency to the latest ^7.4.0 but was hit with the always-lovely:

require() of ES Module /Users/josh/repos/generator-generator/node_modules/yeoman-generator/dist/index.js from /Users/josh/repos/generator-generator/app/index.js not supported.
Instead change the require of /Users/josh/repos/generator-generator/node_modules/yeoman-generator/dist/index.js in /Users/josh/repos/generator-generator/app/index.js to a dynamic import() which is available in all CommonJS modules.

...so using the latest yeoman-generator dependency is blocked on #265.

---

I can't promise exactly when we'll resolve #265 and unblock this issue, but I'm hoping it'll be Soon ™. In the meantime downgraded npm install -g [email protected] generator-generator does seem to fix this issue. I've hidden other comments in this thread to emphasize that. Cheers! 🎩
