Question

当前正在通过一些教程学习Vue js和Express js，但我仍然是这些技术的新手。

无论如何，在教程之后，我都会构建一个小项目，其中有一个包含项目前端的文件夹“ Client”和另一个包含后端的服务器“ Server”。

就在将提交推送到Github之前，一切都很好，但是一旦我做了Github，便发出了一些漏洞，并在修复了npm后运行dev不再起作用。

尝试了多重解决方案，但无济于事，运行 npm cache clean --force

后，重新安装了可疑模块，重新安装了节点模块。

这是我得到的错误

   npm run dev


> client@1.0.0 dev D:\projects\Fullstack web apps\VueJs ExpressJs\tab-tracker\Client
> webpack-dev-server --inline --progress --config build/webpack.dev.conf.js

相关依赖项

“ 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，我会立即提供一切帮助澄清我的问题，因为我说我是Web开发的新手。

更新：我正在尝试找出此类错误的原因，该问题在更新 webpack-dev-server 后出现可以使用的版本：

“ 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

Answer 1

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

对6.x主版本的更新带来了重大变化：您不仅必须将带有配置模式的数组直接传递给CopyWebpackPlugin构造函数，还必须将其包装在{{1}中}对象的属性并将其传递。

旧语法：

patterns

新语法：

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

之所以这样做，是因为构造函数现在支持附加的new CopyWebpackPlugin( { patterns: [ { from: 'src/xxx.ext', to: 'dist/xxx.ext' }, { from: 'src/yyy.ext', to: 'dist/yyy.ext' } ] } )属性： https://webpack.js.org/plugins/copy-webpack-plugin/#options-1

Answer 2

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' },
      ],
    }),
  ],

Answer 3

我有同样的问题。最后，我能够使用

解决它

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

Answer 4

如果您升级到copy-webpack-plugin：package.json中的^ 6.0.3，则在以前复制整个目录时，以下内容应该可以工作：

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/ *来修复它，而不会忽略漏洞，这是您永远都不会做的。

进一步了解https://webpack.js.org/plugins/copy-webpack-plugin/。

Answer 5

这对我有用

在webpack.config.js文件中的

更改 CopyWebpackPlugin

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

希望我能帮忙
