webpacks配置去掉exclude: /node_modules/，webpacks编译通过，但chrome中运行空白，提示 i is not a function

webpacks设置：
```
const path = require('path');
const os = require('os');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const HappyPack = require('happypack');
var happyThreadPool = HappyPack.ThreadPool({ size: os.cpus().length });
function resolve (dir) {
return path.join(__dirname, dir);
}
module.exports = {
entry: {
main: '@/main',
'vender-base': '@/vendors/vendors.base.js',
'vender-exten': '@/vendors/vendors.exten.js'
},
output: {
path: path.resolve(__dirname, '../dist/dist')
},
module: {
rules: [
{
test: /\.vue$/,
loader: 'vue-loader',
options: {
loaders: {
css: 'vue-style-loader!css-loader',
less: 'vue-style-loader!css-loader!less-loader'
},
postLoaders: {
html: 'babel-loader'
}
}
},
{
test: /iview\/.*?js$/,
loader: 'happypack/loader?id=happybabel',
exclude: /node_modules/
},
{
test: /\.js$/,
loader: 'happypack/loader?id=happybabel',

```
exclude: /node_modules/（去掉这一行，webpacks编译通过，但chrome中运行空白提示）
`i is not a function`
```

},
{
test: /\.css$/,
use: ExtractTextPlugin.extract({
use: ['css-loader?minimize', 'autoprefixer-loader'],
fallback: 'style-loader'
})
},
{
test: /\.less$/,
use: ExtractTextPlugin.extract({
use: ['css-loader?minimize','autoprefixer-loader', 'less-loader'],
fallback: 'style-loader'
}),
},
{
test: /\.(gif|jpg|png|woff|svg|eot|ttf)\??.*$/,
loader: 'url-loader?limit=1024'
},
{
test: /\.(html|tpl)$/,
loader: 'html-loader'
}
]
},
plugins: [
new HappyPack({
id: 'happybabel',
loaders: ['babel-loader'],
threadPool: happyThreadPool,
verbose: true
})
],
resolve: {
extensions: ['.js', '.vue'],
alias: {
'vue': 'vue/dist/vue.esm.js',
'@': resolve('../src'),
}
}
};
```

Start with the webpack configuration shown in the issue, especially the .js rule, HappyPack loader, and Babel loader settings. Reproduce the build with exclude: /node_modules/ removed, then inspect the Chrome runtime error and compare it with the excluded configuration. Done means the bundle compiles and the application runs in Chrome without “i is not a function”.
