After upgrading to 2.4.0 I have problem building wasmJs application on CI (locally works ok).

[Robert Jaros]

The error is:

Cannot find node module "webpack/bin/webpack.js" in "/root/.kotlin/kotlin-npm-tooling/yarn/e49be039833f93cd8352f956b903151a"

[Robert Jaros]

After struggling with this for a few hours I'm a bit out of ideas.

@Ilya Goncharov [JB] any idea?

[Ilya Goncharov [JB]]

Do you have task kotlinWasmToolingSetup as executed?
And if comparing with your local build, does the path the same .kotlin/kotlin-npm-tooling/yarn/e49be039833f93cd8352f956b903151a?

[Robert Jaros]

The task is executed.

[Robert Jaros]

But looking at the logs I see it seems the task might not finish in time.

[Robert Jaros]

warning Waiting for the other yarn instance to finish (610)

[Robert Jaros]

Perhaps I'll try to use npm instead of yarn ...

[Ilya Goncharov [JB]]

Hm, usually it means that it waits for other instances to finish. But then it should execute their part of work.
Probably yes, after kotlinWasmToolingSetup task, the folder is empty and there is no node_modules there

[Robert Jaros]

Using npm fixed the issue! Oh my gosh! I wasted half a day on this. 😭

[Robert Jaros]

But thank you for your help. This led me to the solution :)

[Ilya Goncharov [JB]]

Sorry for that. It is another case for the decision to change the default from yarn to npm 🙂
