How do I fix this yew error?

[haughty cave]

I'm using replit and I wonder if this problem caused by replit?

I'm not familiar with Yew, but that is almost certainly Yew saying that it only runs under wasm, but you're trying to run it as a standalone binary on the host

https://docs.rs/yew/latest/yew/ mentions you can enable the ssr feature for server-side rendering, but I imagine that probably requires setup beyond just having a main()

basically right now you have a program that's kinda like a piece of JavaScript that belongs in a web page; you can't just cargo run it and have to set up the environment for it instead

but I don't actually know how to use Yew so I can't tell you how to do that

Use trunk to serve it

cargo install trunk
