目前通过一些教程学习Vue js和express js，我对这些技术还是新手。

无论如何，按照教程，我正在构建一个小项目，其中我有一个包含项目前端的文件夹“Client”和另一个包含后端的文件夹“Server”。

就在将提交推送到 Github 之前，一切都很好，但是一旦我这样做了，Github 就会发出一些漏洞，并且在修复它们之后，npm run dev 就不再工作了。

尝试了多种解决方案但没有任何效果，重新安装可疑模块，运行npm cache clean --force后重新安装节点模块

这是我得到的错误 

   npm run dev

相关依赖

"webpack": "^4.43.0",

"webpack-bundle-analyzer": "^3.3.2",

"webpack-cli": "^3.3.11",

"webpack-dev-server": "^3.1.11",

我希望我为你们提供了一切，如果没有，我会立即提供任何东西来帮助澄清我的问题，因为我说过我是 Web 开发的新手。

更新：我试图找出此类错误背后的原因，更新webpack-dev-server 版本后会出现问题：

“webpack-dev-server”：“^2.9.1”

有错误的版本：

“webpack-dev-server”：“^3.11.0”

如果我忽略发现的漏洞可以吗？因为尝试修复它们会导致此错误。

谢谢

这不是问题webpack本身webpack-dev-server，而是 copy-webpack-plugin插件的问题。

随着 6.x 主要版本的更新带来了重大变化：CopyWebpackPlugin您现在必须将具有配置模式的数组直接传递给构造函数，而不是直接将其包装在patterns对象的属性中并传递它。

旧语法：

    new CopyWebpackPlugin(
      [
        { from: 'src/xxx.ext', to: 'dist/xxx.ext' },
        { from: 'src/yyy.ext', to: 'dist/yyy.ext' }
      ]
    )

新语法：

    new CopyWebpackPlugin(
      { 
        patterns: [
          { from: 'src/xxx.ext', to: 'dist/xxx.ext' },
          { from: 'src/yyy.ext', to: 'dist/yyy.ext' }
        ]
      }
    )

他们这样做是因为构造函数现在支持一个附加options属性： https ://webpack.js.org/plugins/copy-webpack-plugin/#options-1

更新到 3.11 后出现了一个新模板

  plugins: [
    new CopyPlugin({
      patterns: [
        { from: 'source', to: 'dest' },
        { from: 'other', to: 'public' },
      ],
    }),
  ],

我有同样的问题。最后，我能够使用

npm install --save copy-webpack-plugin@5.1.1

如果您在 package.json 中升级到 copy-webpack-plugin: ^6.0.3 ，那么当您之前复制整个目录时，以下应该可以工作：

plugins: [
    new CopyWebpackPlugin({
        patterns: [
            {
                from: "[your-src-dir]/*",
                to: "[your-dst-dir]/*",
            },
        ],
    }),
]

在目录目标和源目录名称之后添加 /* 可以修复它而不会忽略漏洞，这是你永远不应该做的。

查看https://webpack.js.org/plugins/copy-webpack-plugin/了解更多信息。

这对我有用

在 webpack.config.js 文件中更改CopyWebpackPlugin

new CopyWebpackPlugin({
                patterns: [
                  { from: "fonts/**", globOptions: { ignore: [`${relative(appPath, appResourcesFullPath)}/**`] } },
                  { from: "**/*.{jpg,png}", globOptions: { ignore: [`${relative(appPath, appResourcesFullPath)}/**`] } },
                ]
              }),

希望我能帮上忙

使用以下命令将 Angular 工具包版本重置为 2.3.0。

npm i @ionic/angular-toolkit@2.3.0 -E -D
