Dioxus应用启动失败：Bindgen版本不兼容问题求助

问题详情 #

启动新建Dioxus应用时失败，核心错误为Bindgen版本不兼容，具体错误日志如下：

[WARN] Config file: `Dioxus.toml` not found; using default config.
[WARN] Config file: `Dioxus.toml` not found; using default config.
[INFO] 🚅 Running build command...
[INFO] 👑 Build done.

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
[ERROR] 🚫 Serve startup failed: Build Failed: Bindgen build failed! 
This is probably due to the Bindgen version, dioxus-cli using `0.2.81` Bindgen crate.

项目配置文件Cargo.toml：

[package]
name = "dioxus-example"
version = "0.1.0"
edition = "2021"

[dependencies]
dioxus = "0.3.2"
dioxus-web = "0.3.2"
wasm-bindgen = "0.2.78"

main.rs代码：

#![allow(non_snake_case)]
// import the prelude to get access to the `rsx!` macro and the `Scope` and `Element` types
use dioxus::prelude::*;

fn main() {
    // launch the web app
    dioxus_web::launch(App);
}

// create a component that renders a div with the text "Hello, world!"
fn App(cx: Scope) -> Element {
    cx.render(rsx! {
        div {
            "Hello, world!"
        }
    })
}

解决办法 #

1. 统一项目与dioxus-cli的wasm-bindgen版本 #

dioxus-cli当前依赖0.2.81版本的wasm-bindgen，而项目中使用的是0.2.78，版本差异引发构建失败。修改Cargo.toml中的wasm-bindgen版本，与cli保持一致：

[dependencies]
dioxus = "0.3.2"
dioxus-web = "0.3.2"
wasm-bindgen = "0.2.81"

2. 更新dioxus-cli至兼容版本 #

若希望保留项目中的wasm-bindgen版本，可更新dioxus-cli到匹配的最新版本，执行命令：

cargo install dioxus-cli --force

更新完成后重新运行dx serve启动应用。

3. 清理构建缓存后重新构建 #

执行命令清理旧构建缓存，避免残留的版本冲突文件影响构建：

cargo clean

清理完成后再次运行dx serve尝试启动。
