Webpack 4:mini-css-extract-plugin +文件加载器未加载资产 [英] Webpack 4: mini-css-extract-plugin + file-loader not loading assets

问题描述

我正在尝试移动我的.scss个文件之一中使用的素材资源(图像和字体)，但似乎它们被忽略了:

I'm trying to move assets (images and fonts) used in one of my .scssfiles, but it seems that they get ignored:

这是我的 .scss 文件:

@font-face {
    font-family: 'myfont';
    src: url('../../assets/fonts/myfont.ttf') format('truetype');
    font-weight: 600;
    font-style: normal;
}

body {
    color: red;
    font-family: 'myfont';
    background: url('../../assets/images/bg.jpg');
}

这是我的 webpack.config.js :

const path = require('path');
const { CheckerPlugin } = require('awesome-typescript-loader');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");

module.exports = {
    target: 'node',
    entry: path.resolve(__dirname, 'server.tsx'),
    output: {
        filename: 'server_bundle.js',
        path: path.resolve(__dirname, 'build'),
        publicPath: '/build'
    },
    resolve: {
        extensions: ['.ts', '.tsx', '.js', '.jsx']
    },
    module: {
        rules: [{
                test: /\.(tsx|ts)?$/,
                loader: 'awesome-typescript-loader',
                options: {
                    jsx: 'react'
                }
            },
            {
                test: /\.(scss|sass|css)$/,                
                use: [
                    MiniCssExtractPlugin.loader,
                    { loader: 'css-loader', options: { url: false, sourceMap: true } },
                    { loader: 'sass-loader', options: { sourceMap: true } },                    
                ]
            },
            {
                test: /\.(png|svg|jpg|jpeg|gif)$/,
                loader: 'file-loader',
                options: { outputPath: 'public/images' }
            },
            {
                test: /\.(woff|woff2|eot|ttf|otf)$/,
                loader: 'file-loader',
                options: { outputPath: 'public/fonts' }
            }
        ]
    },
    plugins: [
        new CheckerPlugin(),
        new MiniCssExtractPlugin({
            filename: 'public/styles_bundle.css',
            chunkFilename: "public/styles/[id].css"
        })
    ]
}

我在浏览器中得到此 .css 文件作为输出(注意图像名称):

I'm getting this .css file in my browser as the output (Note the name of the image):

body {
  color: red;
  background: url("../../assets/images/myimage.jpg"); 
}

在我的public目录中，我得到了:

And in my public directory I get this:

public/
    styles_bundle.css

这里有两个问题:

1. 字体未编译(无公开/字体/等... )
2. 图像未编译

我一直在尝试一切，但是我不知道这里可能会发生什么...有什么想法吗?

I've been trying everything, but I don't know what may be happening here... Any Ideas?

推荐答案

我刚刚解决了一个类似的问题.如果将url选项更改为true，则可能会看到失败的图像URL引用.

I have just fixed a similar issue. If you change the url option to true, you might see failed image URL references.

{ loader: 'css-loader', options: { url: false, sourceMap: true } },

或者您可以手动检查路径引用是否正确.

Or you can manual check whether the path reference is correct.

url('../../assets/images/bg.jpg')

我认为由于所有图像资源链接都不正确，所以无法创建图像文件夹.

I think the images folder doesn't get created because all the image resource links are incorrect.

对于我要解决的问题，引用均不正确，我无法对其进行修复，因此我只使用了 webpack复制插件可将文件复制到正确的dist文件夹位置.

For the problem I was fixing, the references were all wrong and I couldn't fix them so I just used this webpack copy plugin to copy files to the right dist folder location.
