Issues When Running

[parker-codes]

I can't seem to get the Hello World example from the README running. I have updated my main.rs file and added the dependency to Cargo.toml, but when I run using trunk I get a long list of errors (see below).

Environment

• Maple: 0.4.x
• WSL / Ubuntu 20.04.1 LTS

Additional context
I have updated trunk, wasm-pack-cli, Rust, and a few other dependencies I think are related, just in case.

Here is the start of the output. The list goes on for quite a while longer.

Sorry, I can't reproduce. May I ask what Rust compiler version you are using?

[lukechu10]

Also know that all the examples are hosted on maple-rs.netlify.app/example/example-name (so the hello world example would be at maple-rs.netlify.app/example/hello)

[parker-codes]

rustc 1.51.0 (2fd73fabe 2021-03-23)

I should clarify I'm following the steps in the Getting Started section of the README, so not the actual Hello World example.

[lukechu10]

It seems to be an error with console_error_panic_hook. And also the README.md is slightly out of date. The example should be

render(|| root);

But that doesn't seem to be the cause of the error you posted. Could I take a look at your Cargo.toml please?

[lukechu10]

Could I also see any other code you have?

Here you go! https://github.com/parker-codes/maple-build-error-repro

[lukechu10]

Hmm, I fixed it by running cargo update. Not sure what the problem was there

[parker-codes]

Crazy. Sorry to bother you! 😄 It works now, so I can try more advanced things!
