項目里使用了vue-echarts-v3，由于打包后其中有ES6的代碼，所有將vue-echarts-v3添加到babel-loader的處理范圍內(nèi)。

在webpack.base.conf.js中：

{
    test: /\.js$/,
    loader: 'babel-loader',
    options:{
        plugins: ['syntax-dynamic-import']
    },
    include: [resolve('src'), resolve('test'), resolve('node_modules/vue-echarts-v3'), resolve('node_modules/webpack-dev-server')]
}

.babelrc的配置：

{
    "presets": [
        ["env", {
            "modules": false,
            "targets": {
                "browsers": ["> 1%", "last 2 versions", "not ie <= 8"],
                "node": "current"
            }
        }],
        "stage-2"
    ],
    "plugins": [
        "transform-vue-jsx", "transform-runtime"
    ]
}

然后npm start的時候就報了警告：
warning in ./node_modules/vue-echarts-v3/src/wrapper.js
"export 'default' (imported as '_') was not found in 'lodash'

其他頁面也有引入lodash，但為什么在vue-echarts-v3的wrapper.js中引入會出現(xiàn)這個問題？如果不讓babel-loader去處理vue-echarts-v3就沒問題
