Error: webpack.optimize.CommonsChunkPlugin has been removed, please use config.optimization.splitChunks instead.
在config中添加以上代码后,这个new里面这两行就不需要了是吧?可是删除之后还是报错

按照楼上配置得到左边截图效果,可是怎样打包到指定路径呢?

按官方的文档来做的,竟然不是最新的,也是醉了
请问您也姓佘吗?咱俩同姓,你在哪里
感谢感谢!!!
感谢楼主
这是我的代码:
config.plugins.push(
new ExtractPlugin('styles.[contentHash:8].css')
)
config.optimization = {
splitChunks: {
cacheGroups: {
commons: {
chunks: 'initial',
minChunks: 2, maxInitialRequests: 5,
minSize: 0
},
vendor: {
test: /node_modules/,
chunks: 'initial',
name: 'vendor',
priority: 10,
enforce: true
}
}
},
runtimeChunk: true
}
具体可以查看webpack 4.0版本的修改http://ju.outofmemory.cn/entry/343762
问题已经解决,将解决方法分享给遇到同样问题的朋友.
这个是webpack 4.0版本写法发生改动导致的问题.
在config里添加下边的代码,即可解决
根据提示,使用config.optimization.splitChunks 这个配置依然报错:
TypeError: Cannot read property 'splitChunks' of undefined
