       it looks like the Rust project used to create this wasm file was linked against
       version of wasm-bindgen that uses a different bindgen format than this binary:

         rust wasm file schema version: 0.2.93
            this binary schema version: 0.2.92

       Currently the bindgen format is unstable enough that these two schema versions
       must exactly match. You can accomplish this by either updating this binary or
       the wasm-bindgen dependency in the Rust project.

       You should be able to update the wasm-bindgen dependency with:

           cargo update -p wasm-bindgen --precise 0.2.92

       don't forget to recompile your wasm file! Alternatively, you can update the
       binary with:

           cargo install -f wasm-bindgen-cli --version 0.2.93

       if this warning fails to go away though and you're not sure what to do feel free
       to open an issue at https://github.com/rustwasm/wasm-bindgen/issues!

Additional Context

 ~/projects/spock (main?) $ cargo update -p wasm-bindgen --precise 0.2.92
    Updating crates.io index
error: failed to select a version for the requirement `wasm-bindgen = "=0.2.93"`
candidate versions found which didn't match: 0.2.92
location searched: crates.io index
required by package `spock v0.1.0 (~/projects/spock)`

[daxpedda]

The problem seems to be that a package you depend on, spock, doesn't support downgrading to v0.2.92, presumably because it requires at least v0.2.93.

[acgetchell]

spock is the name of my project that was generated via cargo leptos new --git leptos-rs/start-axum

[daxpedda]

I'm not familiar with Leptos, but I assume you should check the generated Cargo.toml then.
You might be better served if you ask in the Leptos community.

[acgetchell]

Well, I updated to wasm-bindgen = "0.2.95" in Cargo.toml and then recompiled using cargo install -f wasm-bindgen-client--version 0.2.95, but I still get this error. How do you update wasm-bindgen?

[daxpedda]

I might be able to figure out if you share some reproducable example.
But again: you might be much better served asking the Leptos community directly.

[cplmayo]

Was this solved? I am running into the same issue and I haven't been able to find a resolution.

[CodingFlow]

Yes, I found the solution. Need to update cargo-leptos; my guess is that the error is because cargo-leptos is built against specific version of wasm-bindgen. Although I updated to wasm-bindgen 0.2.95. I also updated rust to latest using rustup update and updated all my leptos dependencies to the version in this PR.

No, I gave up and picked a different stack.
