问题说明 ：项目为多入口多输出的应用 ，独立合并了jquery,avalon等插件为common.js，其他单独输出，现在需要babel：es6--转es5，但是转完之后没有报错 但是浏览器不能渲染。moudle的代码被混在了common中， 整个demo chrome 不能解析
现在情况是，我的期望是jQuery四个文件独立为common，但是我在avalon_demo.js中import其他文件moudle.js，按我的想法生成后可能会把moudle和avalon_demo打包，而实际情况是moudle的代码在common中，在浏览器中找不到export的值。我不知道哪里出了问题，哪位大哥大姐能帮帮忙啊。我在这测了好几个小时了
path.resolve(__dirname, './src/pages')这个又exclude又include是干啥？
没提供依赖无法具体帮你测试原因，不过可以试试用babel-preset-env替代babel-preset-es2015，最好弄个.babelrc放在外面写babel的配置项
问题解决 就是添加了minChunks: Infinity 参数 ，和babel配置没关系，问的题目有一点问题，我把网上转的api翻译留在这把，谢谢楼上的兄弟
ptions.name or options.names(string|string[]): 公共模块的名称
options.filename (string): 公开模块的文件名（生成的文件名）
options.minChunks (number|Infinity|function(module,count) - boolean): 为number表示需要被多少个entries依赖才会被打包到公共代码库；为Infinity 仅仅创建公共组件块，不会把任何modules打包进去。并且提供function，以便于自定义逻辑。
options.chunks(string[]):只对该chunks中的代码进行提取。
options.children(boolean):如果为true,那么公共组件的所有子依赖都将被选择进来
options.async(boolean|string):如果为true,将创建一个 option.name的子chunks（options.chunks的同级chunks） 异步common chunk
options.minSize(number):所有公共module的size 要大于number，才会创建common chunk
