javascript - webpack 4.1.1 -> configuration.module 有一个未知的属性 'loaders' 。

Question

我刚刚将 webpack 更新到 4.1.1，当我尝试运行它时出现以下错误:

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema. - configuration.module has an unknown property 'loaders'. These properties are valid: object { exprContextCritical?, exprContextRecursive?, exprContextRegExp?, exprContextRequest?, noParse?, rules?, defaultRules?, unknownContextCritical?, unknownContextRecursive?, unknownContextRegExp?, unknownContextRequest?, unsafeCache?, wrappedContextCritical?, wrappedContextRecursive?, wrappedContextRegExp?, strictExportPresence?, strictThisContextOnImports? } -> Options affecting the normal modules (NormalModuleFactory).

loaders 看起来像这样并与 webpack 3.11.0 一起工作:

module: {
    loaders: [
        { test: /\.tsx?$/, loader: ['ts-loader'] },
        { test: /\.css$/, loader: "style-loader!css-loader" },
        {
            test: /\.scss$/, use: [{
                loader: "style-loader" // creates style nodes from JS strings
            }, {
                loader: "css-loader" // translates CSS into CommonJS
            }, {
                loader: "sass-loader" // compiles Sass to CSS
            }]
        },
        { test: /\.(otf|ttf|eot|svg|woff(2)?)(\?[a-z0-9=&.]+)?$/, loader: 'file-loader?name=./Scripts/dist/[name].[ext]' }
    ]
}

查看 webpack 4.1.1 的加载器示例:

https://webpack.js.org/loaders/raw-loader/

我所要做的就是将 loaders 重命名为 rules。

module: {
    rules: [
        { test: /\.tsx?$/, loader: ['ts-loader'] },
        { test: /\.css$/, loader: "style-loader!css-loader" },
        {
            test: /\.scss$/, use: [{
                loader: "style-loader" // creates style nodes from JS strings
            }, {
                loader: "css-loader" // translates CSS into CommonJS
            }, {
                loader: "sass-loader" // compiles Sass to CSS
            }]
        },
        { test: /\.(otf|ttf|eot|svg|woff(2)?)(\?[a-z0-9=&.]+)?$/, loader: 'file-loader?name=./Scripts/dist/[name].[ext]' }
    ]
}
