roadhog迁移成webpack4问题整理

[webpack-cli] Error: Cannot find module 'object.getownpropertydescriptors'

可能是webpack-cli版本的问题，我的项目是从3.1.1升级到4.9.1好了。

 忘记解决方式了

[webpack-cli] Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'contentBase'. These properties are valid:
   object { allowedHosts?, bonjour?, client?, compress?, devMiddleware?, headers?, historyApiFallback?, host?, hot?, http2?, https?, ipc?, liveReload?, magicHtml?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?, onListening?, open?, port?, proxy?, server?, setupExitSignals?, setupMiddlewares?, static?, watchFiles?, webSocketServer? }

 webpack-cli这个版本devServer中没有这个contentBase属性。

 devServer: {
    // contentBase: resolve(__dirname, "build"),
    static:resolve(__dirname, "build"),
  }

./src/index.js
Module build failed (from ./node_modules/[email protected]@babel-loader/lib/index.js):
Error: Duplicate plugin/preset detected.
If you'd like to use two separate instances of a plugin,
they need separate names, e.g.

 babel-loader版本高8.2.5降为8.0.0，.babelrc.js文件presets中加入@babel/preset-env

/src/routes/Contract/ContractFile/file.pdf 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
(Source code omitted for this binary file)

 忘记配置pdf文件规则，{ test: /\.pdf$/i, use: 'file-loader', },

./src/routes/Attendance/vacationDetail/index.less
Module build failed (from ./node_modules/[email protected]@mini-css-extract-plugin/dist/loader.js):
ModuleNotFoundError: Module not found: Error: Can't resolve './@/assets/font/UnidreamLED.ttf' in 'C:\yt-program\自助webpack4\src\routes\Attendance\vacationDetail'

 mini-css-extract-plugin版本低

chunk styles [mini-css-extract-plugin]
Conflicting order between:
 * css ./node_modules/[email protected]@css-loader/dist/cjs.js??ref--7-1!./node_modules/[email protected]@less-loader/dist/cjs.js??ref--7-2!./src/components/MultipleLov/index.less
 * css ./node_modules/[email protected]@css-loader/dist/cjs.js??ref--7-1!./node_modules/[email protected]@less-loader/dist/cjs.js??ref--7-

 项目中引入相同css样式的组件，引入顺序不一致。需要在mini-css-extract-plugin加入ignoreOrder:true。具体含义参考mini-css-extract-plugin - npm

[webpack-cli] TypeError: Invalid value used in weak set

 mini-css-extract-plugin依赖版本有问题我最终用的时0.9.0

Module build failed (from ./node_modules/[email protected]@mini-css-extract-plugin/dist/loader.js):
ValidationError: Invalid options object. Mini CSS Extract Plugin Loader has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'modifyVars'. These properties are valid:

    at Object.pitch (C:\yt-program\自助webpack4\node_modules\[email protected]@mini-css-extract-plugin\dist\loader.js:53:29)

 mini-css-extract-plugin依赖这个版本没有modifyVars这个属性，看过版本说明之后才知道高版本移除这个属性了，1.3.6降为0.9.0，成功解决。

pre-commit:
pre-commit: We've failed to pass the specified git pre-commit hooks as the `precommit`
pre-commit: hook returned an exit code (1). If you're feeling adventurous you can
pre-commit: skip the git pre-commit hooks by adding the following flags to your commit:
pre-commit:
pre-commit:   git commit -n (or --no-verify)
pre-commit:
pre-commit: This is ill-advised since the commit is broken.

 代码规范检测不过，删除根目录下.git/hooks的pre-commit文件。

webpack.config.production.js中rules的css配置不对，改为

{ test: /\.css$/, use: [ MiniCssExtractPlugin.loader, { loader: 'css-loader', options: { importLoaders: 1, }, }, 'postcss-loader', ], },

Unhandled promise rejection Error: Loading chunk 144 failed.

页面白屏

 webpack.config.production.js中的output.publicPath:'./'改为’/‘，就好了。

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: C:\yt-
program\自助webpack4\node_modules\[email protected]@chalk\source\index.js
require() of ES modules is not supported.
require() of C:\yt-program\自助webpack4\node_modules\[email protected]@chalk\source\i
ndex.js from C:\yt-program\自助webpack4\webpack.config.production.js is an ES mo
dule file as it is a .js file whose nearest parent package.json contains "type":
 "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(
), or remove "type": "module" from C:\yt-program\自助webpack4\node_modules\_chal
[email protected]@chalk\package.json.

chalk依赖版本过高，造成es6无法解析， 5.0.1降到4.0.0，成功修复问题。

发到服务器，点开部分页面，控制台报React is not defined

因为部分组件缺少了react依赖，可以在webpack.config.js的plugins配置插件

new webpack.ProvidePlugin({ // 根据上下文，在需要依赖React处，自动引入
    "React": "react",
})

@connect装饰器报错

HOC 的装饰器写法，需要配置 babel 支持。现在 webpack 一般都不直接在自身配置文件里面设置 babel 了，而是将 babel 的配置信息抽出来放到.babelrc内以 JSON 格式维护，在plugins内加入下面这段即可：

["@babel/plugin-proposal-decorators", { "legacy": true }],
