Am I doing something wrong here or is this a regression?

I am trying out wasm-pack for the first time and also hit this issue. But I think I found the solution. Update to:
wasm-bindgen="0.2.12"
and adjust your features to:
#![feature(use_extern_macros, wasm_import_module)]
That was enough at least for me to get a hello world to compile.
If I am understanding correctly, this is fallout from this rust change and this wasm-bindgen change.

hey @ef4 and @Mackiovello - this is exactly correct. will be updating the tutorials today- unless someone wants to make the PR to the docs! thanks for filing <3

@ashleygwilliams we would have to update the error message for wasm-pack init too since it specifically asks you to add wasm-bindgen = "0.2". I can create a PR later today for the docs and the error message unless someone else does it before me.

After looking at this, it seems like the only thing needed to fix it was to update rust with rustup update nightly. It works even if I don't set wasm-bindgen to 0.2.12 or set any feature flags. So do we actually need to update anything? I'm not able to reproduce with latest nightly.

on 20 Jul 2018
oh huh. thanks for the research @Mackiovello i'll take a look now and see if i can reproduce and if we need any sort of update. i'm giving a talk on this tonight so it's important haah!

@Mackiovello i was able to reproduce. i think it's best for us to update the example to be inline with wasm-bindgen anyways. i'll be filing a PR :)

heads up this will be included in a point release i intend to get out today! thanks again for the report- i super appreciate it <3 :)

I can't init the project even with features adjusted, would you like to point out where i did wrong? Thanks!

I can't init the project even with features adjusted, would you like to point out where i did wrong?
Have you tried to update to the latest nightly with rustup update nightly?
