Calling launch in kotlinjs causes a TypeError to be logged

[ansman]

If you compile the following code and execute it:

fun main(args: Array<String>) {
  launch {}
}

You get the following exception printed to the terminal:

TypeError: throwCCE is not a function

I can't reproduce this problem on my machine.
Could you please provide more details (node.js version, Kotlin version, build script etc.) or self-contained project example?

[ansman]

Sure, no problem. I've attached a same project.

Just cd in to the dir and run npm run bug

coroutines-bug.zip

I had the same bug and resolved it, when you include kotlin and kotlinx-coroutines-core in your package.json, kotlinx-coroutines-core will download kotlin as a dependency and put it in its own node_modules, leading to a conflict between kotlin installed by package.json and the one installed by kotlinx-coroutines-core, if you remove kotlin from package.json everything works fine. It looks like the kotlinx-coroutines-core npm package can't detect when the package.json already contain kotlin

Seems like it could be solved by fixing #339 then

@elizarov any idea when this will be released? Or are there snapshot builds we could use? Coroutines are basically unusable in JS, seems like a big deal. 😕
