铁锈与瓦西姆惯性装置

Question

我遵循本教程创建一个使用铁锈的组件应用程序，但是当我尝试使用节点运行捆绑的web程序集代码时(在添加我自己的代码之前，同时严格遵循本教程)。

$ 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依赖关系

  "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"
  }

我和以前一样重做了教程，得到了同样的结果。我认为这是我建立国家预防机制的一个问题，但我不确定。

Answer 1

由于安全警报，当我从教程文件中指定的副本webpack插件的版本更新时，我也犯了类似的错误。配置参数的格式同时发生变化，因此我不得不更改它们以匹配它们。

教程中有"copy-webpack-plugin": "^5.0.3"，我升级到了"copy-webpack-plugin": "^6.0.3"，在webpack.config.js中，我不得不更改

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

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

我不熟悉webpack或复制webpack插件，除了通过相同的锈蚀-是你遵循的教程，所以使用这个建议，你自己的风险，我只能说，它似乎是有效的。

Answer 2

在尝试从同一个npm run start运行教程时，也出现了类似的错误。

我的错误是没有LTS版本的Node.js，而是最新版本的。

• 我完全移除了我的Node.js 以下这些步骤
• 并安装了安全LTS
