fresh install won't run

[dominikwilkowski]

If I install a completely fresh folder via cargo leptos new --git leptos-rs/start-axum I get an error for the wasm-bindgen = "=0.2.93" dependency:

       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!

If I then downgrade that dependency I get a bunch of different errors:

I'm on latest nightly on latest macos on M1 arm64.

   stable-aarch64-apple-darwin unchanged - rustc 1.80.1 (3f5fd8dd4 2024-08-06)
  nightly-aarch64-apple-darwin unchanged - rustc 1.82.0-nightly (6de928dce 2024-08-18)

I can't reproduce this issue with the latest version of cargo-leptos: it is likely you need to update it. wasm-bindgen-cli needs to update on every patch release, so we often need to combine an update to cargo-leptos with an update to the wasm-bindgen version.

Ping me if updating doesn't fix the issue.

[dominikwilkowski]

Can confirm that after installing the latest cargo-leptos the problem went away (though I had to blow up the newly created folder and re-create it).

Thank you

λ cargo leptos -V
cargo-leptos 0.2.17

Actually not the same but rather this part:
