Question

当我尝试在ReactJs中使用material-ui-dropzone时，我收到如下错误。

    ERROR in ./node_modules/material-ui-dropzone/src/index.js
Module parse failed: /home/buddhik/Documents/InternWork/React/licensemanager/node_modules/material-ui-dropzone/src/index.js Unexpected token (106:31)
You may need an appropriate loader to handle this file type.

这是我的webpack.config.js文件。

const path = require('path');

module.exports = {
    context: path.resolve(__dirname, './src'),
    entry: {
        index: './index.js',
    },
    output: {
        path: path.resolve(__dirname, './dist'),
        filename: 'bundle.js',
    },
    module: {
        loaders: [
            {
                test: /\.html$/,
                use: [{
                    loader: 'html-loader',
                }],
            },
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: [
                    {
                        loader: 'babel-loader',
                        query: {
                            presets: ['es2015', 'react'],
                        },
                    },
                ],
            },
            {
                test: /\.(png|jpg|svg|cur|gif|eot|svg|ttf|woff|woff2)$/,
                use: ['url-loader'],
            },
            {
                test: /\.jsx?$/,
                exclude: /(node_modules)/,
                loader: 'babel-loader',
                query: {
                    presets: ['es2015', 'react'],
                },
            },
            {
                test: /\.css$/,
                use: ['style-loader', 'css-loader'],
            },
            {
                test: /\.(js|jsx)$/,
                exclude: /node_modules/,
                loader: 'eslint-loader',
            },
            {
                test: /\.scss$/,
                use: [{
                    loader: 'style-loader',
                }, {
                    loader: 'css-loader',
                }, {
                    loader: 'sass-loader',
                }],
            },

        ],
    },
    resolve: {
        extensions: ['.js', '.json', '.jsx', '.scss'],
    },
    devServer: {
        contentBase: path.join(__dirname, 'public'),
        publicPath: '/dist',
        historyApiFallback: {
            index: '/dist/bundle.js',
          }
    },

};

这是我的package.json文件。

有人可以帮忙解决此问题吗？

您将在以下

中排除node_modules

        {
            test: /\.js$/,
            exclude: /node_modules/,
            use: [
                {
                    loader: 'babel-loader',
                    query: {
                        presets: ['es2015', 'react'],
                    },
                },
            ],
        },

删除exclude: /node_modules/'，我认为没有理由解决这个问题。

虽然可以解决问题，但您可能希望对加载程序test: /\.jsx?$/执行相同的操作。

意外的标记。您可能需要适当的加载程序来处理此文件类型
