Question

我创建了一个Nuxt.js骨架：

yarn create nuxt-app myapp

然后我添加css-loader和手写笔加载器：

yarn add css-loader
yarn add stylus stylus loader

然后我将它们添加到nuxt.config.js：

build: {
    /*
    ** You can extend webpack config here
    */
    extend(config, ctx) {
      // Run ESLint on save
      if (ctx.isDev && ctx.isClient) {
        config.module.rules.push({
          enforce: 'pre',
          test: /\.(js|vue)$/,
          loader: 'eslint-loader',
          exclude: /(node_modules)/
        })
        config.module.rules.push({
          test: /\.css$/,
          loader: ['css-loader', 'stylus-loader'],
          exclude: /(node_modules)/
        })
      }
    }
  }

我在运行yarn run dev时得到了这个信息：

begueradj@begueradj:~/myapp$ yarn run dev
yarn run v1.10.1
$ nuxt

我在做什么错了？

编辑：

为什么我将这些加载程序添加到nuxt.config.js中？因为，例如，在here上说，仅安装扩展程序是不够的，除非您扩展了webpack配置。而要在Nuxt中这样做，我们必须similarly按照我所做的操作（我想）

Answer 1

您的讨论对我有帮助！我的步骤（如果您在全球范围内拥有手写笔）：

npm install stylus-loader stylus --save-dev

就是这样。之后，您可以在项目中自动使用手写笔。

Answer 2

[相当长的延迟回答。但会帮助某人获得最新的nuxt版本（^ 2.14）]

问题讨论中的解决方案nuxt issue 参考webpack stylus options 对于最新版本（2.14.7），

扩展映射所有加载程序的webpack配置，

build: {
    extend (config, { isDev, isClient }) {
      [].concat(...config.module.rules.find(e => e.test.toString().match(/\.styl/)).oneOf.map(e => e.use.filter(e => e.loader == 'stylus-loader'))).forEach(stylus => { 
        Object.assign(stylus.options, {
          //preferPathResolver: 'webpack',
          sourceMap: true,
          stylusOptions: { 
            //use: ['nib'],
            include: ['~assets/styles'],  //include all styl files from folder
            import: [
              '~assets/style/main.styl',  //your main styl file
            ],
          },
        })
        //console.log(stylus)
      }) 
    },

这将导入文件并包括手写笔文件夹。

如何将css-loader和stylus-loader添加到nuxt.config.js中？
