error: linking with rust-lld failed: signal: 6

I'm unable to build the js-hello-world example project. Googled around for about an hour and can't seem to figure out the issue so thought I'd post open an issue here.

Here is the output when I try to build the js-hello-world example from the guide.

$ cargo clean
$ cargo +nightly build --target wasm32-unknown-unknown
error: linking with `rust-lld` failed: signal: 6

I'll keep trying things in the meantime, but hopefully somewhere here might know the problem/solution!
