without-a-bundler-no-modules example does not build

[j-devel]

Describe the Bug

The without-a-bundler-no-modules example does not build.

Steps to Reproduce

1. git clone https://github.com/rustwasm/wasm-bindgen
2. cd wasm-bindgen/examples/without-a-bundler-no-modules/
3. wasm-pack build --target no-modules
4. See the error below.

Expected Behavior

Build finishes without errors.

Actual Behavior

Build fails leaving an error (using rustc 1.45.0-nightly (a74d1862d 2020-05-14)):

thread 'main' panicked at 'internal error: entered unreachable code', crates/cli-support/src/decode.rs:157:1
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Error: Running the wasm-bindgen CLI
Caused by: failed to execute `wasm-bindgen`: exited with exit code: 101

Additional Context

It seems like a regression after merging #2105
The same build works before the merge.

hey there. We ran into the same thing yesterday here. Turns out you have to copy the example's folder (in your case without-a-bundler-no-modules) somewhere out of the wasm-bindgen repo

Indeed yes I believe this is the same issue, closing in favor of that.

Confirmed! Thanks for pointing it out @wattux
