Problem I am unable to build even the simplest Yew applications using Rust 1.76 and running under macOS 14.3

Steps To Reproduce Run cargo install trunk. Run rustup target add wasm32-unknown-unknown Goto any Yew app folder and run trunk serve.

I have tried the YT video at https://discord.com/channels/701068342760570933/1213256829195522148/1213256829195522148 as well as Yew's own sample app, described on https://discord.com/channels/701068342760570933/1213256829195522148/1213256829195522148 Moreover, I have git cloned the entire Yew repo and cannot build and run any of the example apps>

Expected behavior I expect to be able to open my browser to 1287.0.0.1:8080 and run any of the apps.

Screenshots This is an example of the errors which occur...

Problem solved 😃 I had previously installed Rust 1.75.0 via home brew and then forgotten about it.

More recently I had installed Rust 1.76.0 via the official curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs/ | sh command, but it effectively meant I had two copies of cargo floating around.

It hadn't caused my dealings with Rust any undue effects, to my knowledge at least, except where WASM was concerned.

I ran brew uninstall rust and rustup self uninstall followed by curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs/ | sh again, then rustup target add wasm32-unknown-unknown and cargo install trunk. Everything works now 😃
