意外字符'@'您可能需要适当的加载程序来处理此文件类型

问题描述

这是我尝试运行webpack时得到的:我得到的错误是:

This is what I get when I try to run webpack: the error I get is:

它无法解决，对此有任何想法吗?

it can't resolve @import, any ideas on this?

我的webpack配置如下:

my webpack config is as follow:

    const childProcess = require('child_process')
    const CopyWebpackPlugin = require('copy-webpack-plugin')
    const ExtractTextPlugin = require('extract-text-webpack-plugin')

    const webpack = require('webpack')
    const path = require('path')

    const ENV = {
      NODE_ENV: process.env.NODE_ENV,
      API: 'https://accounts' + (process.env.NODE_ENV === 'prd' ? '' : '-'
    + process.env.NODE_ENV),
      BUILD_VERSION: trimEnd(childProcess.execSync('git rev-list HEAD --
    count').toString(), '\n'),
      BUILD_DATE: trimEnd(childProcess.execSync('git log --format="%cd" -n
    1').toString(), '\n'),
      BUILD_COMMIT_ID: trimEnd(childProcess.execSync('git log --format="%h"
    -n 1').toString(), '\n')
    }

    process.env.NODE_ENV === 'prd'

推荐答案

您正在配置文件中两次使用(scss | css).删除它并使用发布的代码打击:使用之前，必须先npm install raw-loader.我认为您已经安装了sass-loader.

You are using the (scss|css) twice in your configuration file.Remove that and use the code posted blow:Before using, you must first npm install raw-loader.I think you've already installed the sass-loader.

{
  test: /\.css$/,
  include: helpers.root('src', 'app'),
  loader: 'raw-loader'
},
// // css global which not include in components
{
  test: /\.css$/,
  exclude: helpers.root('src', 'app'),
  use: ExtractTextPlugin.extract({
    use: 'raw-loader'
  })
},

{
  test: /\.scss$/,
  include: helpers.root('src', 'app'),
  use: ['raw-loader', 'sass-loader']
},
// // SASS global which not include in components
{
  test: /\.scss$/,
  exclude: helpers.root('src', 'app'),
  use: ExtractTextPlugin.extract({
    use: ['raw-loader', 'sass-loader']
  })
}

添加我的root()功能.

var path = require('path');
var _root = path.resolve(__dirname, '..');
function root(args) {
    args = Array.prototype.slice.call(arguments, 0);
    return path.join.apply(path, [_root].concat(args));
}
exports.root = root;

希望这会起作用.
