This is, unfortunately, many developers’ first roadblock when getting started with WebAssembly. They assume that if they just have rustc installed and pass a –target=wasm flag that they’ll get something they could load in a browser. You may be able to get a WebAssembly file doing that, but it will not have any of the required platform integration. If you figure out how to load the file using the JS API, it will fail for mysterious and hard-to-debug reasons. What you really need is the unofficial toolchain distribution which implements the platform integration for you.
