安装worker-build

注意看 wrangler.toml，它每次构建都会运行：

[build]
command = "cargo install -q worker-build && worker-build --release"

不如我们直接：

cargo install worker-build

然后修改 wrangler.toml：

[build]
command = "worker-build --release"

安装wasm-pack

cargo install wasm-pack

Cargo安装可能会报openssl编译错误，建议直接下载：
https://github.com/rustwasm/wasm-pack
https://rustwasm.github.io/wasm-pack/

安装wasm-bindgen-cli

这是每次运行npm run dev的输出：

[INFO]: ⬇️  Installing wasm-bindgen...
  Downloaded wasm-bindgen-cli v0.2.84

不如直接：

cargo install wasm-bindgen-cli

这样它就不会再次检测下载了

npm run dev

$ npm run dev

> template-worker-rust@0.0.0 dev F:\worker\worker-rust
> wrangler dev --local

 ⛅️ wrangler 2.16.0 (update available 2.17.0)
