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 已使用与 API 架构不匹配的配置对象进行初始化。

  • 配置有一个未知的属性“applyWebpackOptionsDefaults”。 这些属性是有效的:object { amd?、baail?、cache?、context?、dependencies?、devServer?、devtool?、entry?、experiments?、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?,记录输入路径?,记录输出路径?,记录路径?,解析?,resolveLoader?,快照?, 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: plugins: [ new webpack.LoaderOptionsPlugin({ // test: /.xxx$/, // 可能仅适用于某些模块 options: { applyWebpackOptionsDefaults: ... } }) ]

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, config, appName, urls, useYarn });

此更改将修复您当前的错误,但您可能会得到下一个 :)

也尝试为 webpack 5 更新您的node部分。 什么是

node: {
    dgram: 'empty',
    fs: 'empty',
    net: 'empty',
    tls: 'empty',
    child_process: 'empty',
}

必须在resolve.fallback之下。

来源: https : //webpack.js.org/migrate/5/#clean-up-configuration

PS 还尝试检查其他迁移说明,以防万一;)

new webpack.LoaderOptionsPlugin({
      options: {
        applyWebpackOptionsDefaults: {},

从你的代码...
