问题描述
我正在尝试将 Webpack 4 升级到 Webpack 5。但是，当我运行 npm start 时出现此错误。有趣的是我没有在任何地方使用 applyWebpackOptionsDefaults 并且在搜索 node_modules 之后我看到它在 webpack lib 中使用了很多次。谁能告诉我我做错了什么？有没有我没有更新的包？我错过了什么？
编译失败。
无效的配置对象。 Webpack 已使用配置对象进行初始化 与 API 架构不匹配。
- 配置有一个未知的属性“applyWebpackOptionsDefaults”。这些属性有效： 对象 { amd？，保释？，缓存？，上下文？，依赖关系？，devServer？，devtool？，入口？， 实验？，externals？，externalsPresets？，externalsType？，ignoreWarnings？，infrastructureLogging？，loader？，模式？，模块？，名称？，节点？，优化？，输出？，并行性？，性能？，插件？，配置文件？ 、recordsInputPath?、recordsOutputPath?、recordsPath?、resolve?、resolveLoader?、snapshot?、stats?、target?、watch?、watchOptions? } -> 用户提供的选项对象。 对于错别字：请更正。 对于加载器选项： webpack >= v2.0.0 不再允许在配置中自定义属性。 应该更新加载器以允许通过 module.rules 中的加载器选项传递选项。 在加载器更新之前，可以使用 LoaderOptionsPlugin 将这些选项传递给加载器： 插件： [ 新的 webpack.LoaderOptionsPlugin({ // 测试：/.xxx$/,// 可能仅适用于某些模块 选项： { applyWebpackOptionsDefaults: ... } }) ]

解决方法
您需要修复 scripts/start.js 文件。
这个文件中有一行：
const compiler = createCompiler(webpack,config,appName,urls,useYarn);
你需要把它改成
const compiler = createCompiler({ webpack,useYarn });
此更改将修复您当前的错误，但您可能会得到下一个 :)
,尝试为 webpack 5 更新您的 node 部分。什么是
node: {
dgram: 'empty',fs: 'empty',net: 'empty',tls: 'empty',child_process: 'empty',}
必须低于 resolve.fallback。
