Programming WebAssembly with Rust: building Rogue WebAssembly game
I’m trying to build the Rogue WebAssembly game from chapter 4, using the code provided on the website.
In build.sh, the wasm-bindgen command is failing with the stack-trace at [1] below. My version of wasm-bindgen is 0.2.67. I have tried changing the Cargo.toml file to “0.2”, instead of “^0.2”, but the result is the same.
thanks!
Michael
p.s. I am enjoying the book, though it might be better to have the code hosted on GitHub?

With wonderful help from friends [1], here are steps that enabled the jsint_roguewasm example on my machine:
- edit
index.jsto import from./pkg/roguewasminstead of./roguewasm - edit
src/lib.rsto import from../indexinstead of./index - in
build.sh, replace thewasm-bindgencommand withwasm-pack build
