Instead of using emscripten, does building for the wasm target work? Try:
cargo web build --target=wasm32-unknown-unknown

I have the same issue.
Can confirm that running cargo web start --target=wasm32-unknown-unknown works.
It issues some warnings about debug builds being broken and forcing a release build, but it works.

Seems similar to #412 .
It appears to be a version mismatch with your version of emscripten 1.38.11. Maybe try using the bundled version of 1.37.27-1 at the time of writing. can check it roughly here: https://github.com/koute/cargo-web/blob/master/src/emscripten.rs
Also maybe check cargo-web on other projects to see if anything deeper could be the issue?

@trsh what version of rust are you using?
error[E0554]: #![feature] may not be used on the stable release channel
Consider trying the latest nightly.
jamartin9

@jamartin9 what then would build command look like?
trsh
on 10 Nov 2018
@trsh the command could vary on your setup but the previous error message suggests you are using the stable branch of rust where the feature gates are not available.
Assuming you are using rustup for managing your rust toolchains:
rustup run nightly cargo web build --target=wasm32-unknown-unknown
To save on verbosity you can just set the default to nightly with rustup too(rustup default nightly).

for me also fails all following options
// in yew/examples/dashboard
cargo web start
cargo web start --target=asmjs-unknown-emscripten
cargo web start --target=wasm32-unknown-unknown
results in smth like

@shershen08, try to run rustup target add wasm32-unknown-unknown as written in readme
