在我学习生锈的旅程中，我决定拿起这本书，名为"Practical Rust Web Projects" by Shing Lyu。
在上一章中，您浏览了使用wasm-pack包装WebAssembly模块的示例，并在NodeJS应用程序中使用.WASM二进制。在我需要编译应用程序的步骤中，我遇到了以下错误：
$ npm run build
> create-wasm-app@0.1.0 build
> webpack --config webpack.config.js
node:internal/crypto/hash:71
this[kHandle] = new _Hash(algorithm, xofLen);

Node.js v18.7.0
经过一些谷歌搜索后，我遇到了建议运行以下命令的人：
$ export NODE_OPTIONS=--openssl-legacy-provider
然后再次运行构建命令，然后编译ð
$ npm run build

这绝对不是生产场景中的适当解决方案，但足以让我通过示例ð
