`cargo install cargo-leptos` fails in dev, cannot run app

[alectrocute]

Hi friends!

I've been daydreaming about contributing to the new UI and finally decided to clone it and get started familiarizing myself with it/the framework today. I'm on macOS 15.0 on an M1 arch.

Running into this issue after attempting to following the instructions in CONTRIBUTING.md:

lemmy-ui-leptos git:(main) ✗ cargo install cargo-leptos

    Updating crates.io index
  Installing cargo-leptos v0.2.20
    Updating crates.io index
error: failed to compile `cargo-leptos v0.2.20`, intermediate artifacts can be found at `/var/folders/3b/s22tvgl57r5fbtnrb7hq84nr0000gn/T/cargo-installEJPfnI`

Caused by:
  failed to select a version for `wasmparser`.
      ... required by package `wasm-bindgen-wasm-conventions v0.2.93`
      ... which satisfies dependency `wasm-bindgen-wasm-conventions = "=0.2.93"` of package `wasm-bindgen-cli-support v0.2.93`
      ... which satisfies dependency `wasm-bindgen-cli-support = "=0.2.93"` of package `cargo-leptos v0.2.20`
  versions that meet the requirements `^0.212` are: 0.212.0

  the package `wasm-bindgen-wasm-conventions` depends on `wasmparser`, with features: `indexmap` but `wasmparser` does not have these features.
   It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.

  failed to select a version for `wasmparser` which could resolve this conflict

Did some googling on the issue and found this but the advice there didn't help.

I'm a Rust newbie so any help appreciated.

Thx, we'd love any help we could get on this!

What version of rust are you on? I'm fairly sure an updated nightly is needed, so run :

rustup update
rustup default nightly
rustup target add wasm32-unknown-unknown
cargo install cargo-leptos
cargo leptos watch

Most of this is from our woodpecker CI setup.
