Module not found: Error: Cannot resolve 'file' or 'directory' (import sass in webpack)

Question

我的项目结构是：

/src/styles/main.scss

@import 'materialize/sass/materialize.scss';

....

我这里也试试@import './materialize/sass/materialize.scss'; 不工作。

只有当我在 index.js

中导入库时它才有效

/src/index.js（有效）

import './styles/reset.css';
import './styles/main.scss';
import './styles/font-awesome/font-awesome.scss';

webpack 加载器：

loaders: [
  {
    test: /\.js?/,
    exclude: [/node_modules/, /styles/],
    loaders: ['babel'],
    include: path.join(__dirname, 'src')
  },
  {
    test: /\.scss$/,
    loader: 'style!css!sass'
  },
  {
    test: /\.css$/,
    loader: "style-loader!css-loader"
  },
  {
    test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
    loader: 'url-loader?limit=10000&mimetype=application/font-woff'
  },
  {
    test: /\.(ttf|eot|svg)(\?v=[0-9]\.[0-9]\.[0-9])?$/,
    loader: 'file-loader'
  }

]

但出现错误：

看起来 webpack 搜索了错误的目录，而不是搜索 materialize 下的 fonts 文件夹。

我每次将 import sass lib 放入 main.scss 时都会出错，这迫使我将 import 放入 index.js。无论如何解决方法？

更新：

我发现里面有配置 \src\styles\materialize\sass\components\_variables.scss:

$roboto-font-path: "../fonts/roboto/" !default;

但它与components有关，这是 webpack 的错误吗？

Answer 1

我认为这是与 css-loader 或 sass-loader 相关的问题，不知何故它们在 node_modules 中并没有真正正确地解析路径。这就是您出现这些错误的原因。

查看错误：

Error: Cannot resolve 'file' or 'directory' ../fonts/roboto/Roboto-Bold.woff in E:\Project\simple-redux-boilerplate\src\styles

css-loader 似乎正试图在您的 src/styles 文件夹中找到 ../fonts/。

作为 解决方法，您可以将放置字体的 "correct" 位置指定为 $roboto-font-path 变量。如果通过 npm install materialize-css 安装，您可以执行以下操作：

$roboto-font-path: '~materialize-css/fonts/roboto/';

波浪号 (~) 字符会告诉您的装载程序查看 node_modules。然后，在解析您的路径时，您的加载器将寻找正确的位置并且不会有错误。

I think (and tested it locally) you don't need to use the tilde character to look at node_modulesusing sass-loader.

如果您不想研究node_modules（因为您更喜欢手动下载依赖项），您可以只使用相对路径。在你的情况下 $roboto-font-path: './materialize/fonts/roboto/'; 应该修复它。

更新：

您也可以尝试使用 resolve-url-loader，它会尝试为您修复网址。
