Rust 和 Wasm 初始设置

Question

我正在关注this tutorial 使用 rust 创建 webassembly 应用程序，但是当我尝试使用 node 运行捆绑的 web 程序集代码时（在添加我自己的任何代码之前并完全按照教程进行操作）

$ npm run start
> create-wasm-app@0.1.0 start /Users/jakearmendariz/Desktop/wasm/wasm-game-of-life/www
> webpack-dev-server

/Users/jakearmendariz/Desktop/wasm/wasm-game-of-life/www/node_modules/copy-webpack-plugin/node_modules/schema-utils/dist/validate.js:98
    throw new _ValidationError.default(errors, schema, configuration);
    ^

ValidationError: Invalid options object. Copy Plugin has been initialized using an options object that does not match the API schema.
 - options[0] should be an object:
   object { patterns, options? }

webpack.config

const CopyWebpackPlugin = require("copy-webpack-plugin");
const path = require('path');

module.exports = {
  entry: "./bootstrap.js",
  output: {
    path: path.resolve(__dirname, "dist"),
    filename: "bootstrap.js",
  },
  mode: "development",
  plugins: [
    new CopyWebpackPlugin(['index.html'])
  ],
};

package.json 依赖项

  "dependencies": {
    "minimist": "^1.2.5",
    "wasm-game-of-life": "file:../pkg"
  },
  "devDependencies": {
    "copy-webpack-plugin": "^6.1.0",
    "hello-wasm-pack": "^0.1.0",
    "webpack-cli": "^3.1.0",
    "webpack-dev-server": "^3.11.0"
  }

我像以前一样重新编写了教程，得到了相同的结果。我认为这是我的 npm 设置的问题，但我不确定。

由于安全警报，当我从教程文件中指定的版本更新 copy-webpack-plugin 的版本时，我遇到了类似的错误。配置参数的格式同时发生了变化，所以我不得不更改它们以匹配。

教程有"copy-webpack-plugin": "^5.0.3"，我升级到"copy-webpack-plugin": "^6.0.3"，在webpack.config.js我不得不改变

    new CopyPlugin([
      path.resolve(__dirname, "static")
    ]),

    new CopyPlugin({
      patterns: [
        path.resolve(__dirname, "static")
      ]
    }),

我不熟悉 webpack 或 copy-webpack-plugin，除了通过你正在遵循的相同的 rust-wasm 教程，所以使用这个建议需要你自担风险；我只能说它似乎有效。
