我正在尝试升级react-toolbox的cljsjs包，这需要将整个项目从 ES6 编译到 ES5。我收到此错误：

You may need an appropriate loader to handle this file type.
| export { default as ProgressBar } from './progress_bar';
| export * from './radio';
| export Ripple from './ripple';
| export { default as Slider } from './slider';
| export { default as Snackbar } from './snackbar';

瑞波币似乎是令人讨厌的标志。有什么想法吗？

完整文件包含：

import './utils/polyfills'; // Import polyfills for IE11

export { overrideComponentTypeChecker } from './utils/is-component-of-type';
export { default as AppBar } from './app_bar';
export { default as Autocomplete } from './autocomplete';
export { default as Avatar } from './avatar';
export * from './button';

export { default as Dialog } from './dialog';
export { default as Drawer } from './drawer';
export { default as Dropdown } from './dropdown';

到目前为止，我正在构建的 webpack 配置如下所示：

const pkg = require('./package');
const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');

const entryName = "react-toolbox.inc";

const extractCss = new ExtractTextPlugin({ filename: entryName + '.css', allChunks: true });

module.exports = {
    target: 'web',
    context: __dirname,
    entry: path.join(__dirname, "packages", "react-toolbox", "src", "components", "index.js"),
    externals: {
        "react": "React",
        "react-dom": "ReactDOM",
        "react-addons-css-transition-group": "React.addons.CSSTransitionGroup"
    },
    output: {
        path: __dirname,
        filename: entryName + '.js',
        libraryTarget: 'var',
        library: 'ReactToolbox'
    },
    resolve: {
        extensions: ['.js', '.css', '.json'],
        modules: ['node_modules']
    },
    module: {

                include: [
                    path.join(__dirname, './components'),
                    path.join(__dirname, './spec')

                            },
                        },
                        'postcss-loader'
                    ]})
            }
        ]
    },
    plugins: [
        new webpack.LoaderOptionsPlugin({
            options: {

                        }),
                        require('postcss-mixins')(),

        })
    ]
};

错误就是它所说的

export Ripple from './ripple';

不是有效的 ES6。它需要是

export {default as Ripple} from './ripple';

您当前的代码需要加载https://babeljs.io/docs/plugins/transform-export-extensions/。
