🤔 Expected Behavior

It should build.

👟 Steps to reproduce

I've just created a new project on Windows 10 by following the game of life book.
The error occurred when I ran wasm-pack.

🌍 Your environment

Include the relevant details of your environment.
wasm-pack version: 0.6.0
rustc version: 1.33.0
os: Windows 10

I've found a related issue: #512 where you suggested to manually install wasm-bindgen which I tried. However I've got the following error:

PS C:\Users\Outpox\Projects\wasm-game-of-life> cargo install wasm-bindgen
    Updating crates.io index
  Installing wasm-bindgen v0.2.38
error: specified package has no binaries

I'd blindly guess that wasm-bindgen has not yet been build against the 1.33.0 compiler for Windows?

(Btw I was able to make this work on Linux Mint earlier today).

Same error on ubuntu. Trying to build wasm-bindgen examples.

@Outpox ,

manually running cargo install wasm-bindgen-cli according to https://github.com/rustwasm/wasm-pack/issues/512 fixed this issue for me.

[Outpox]

Oh right that's my bad. I did cargo install wasm-bindgen instead of cargo install wasm-bindgen-cli.
Using the correct command I was able to build the project.

[ashleygwilliams]

this seems like it is fixed! closing- please reopen or file a new issue if this is still an issue.
