webpack1x cannot read property 'call' of undefined
1.webpack1X cannot read property 'call' of undefined打完包浏览器就是这个错误
2.modules[moduleId].call(module.exports, module, module.exports, __webpack_require__);
3.Cannot read property 'call' of undefined
4.听说网上说typeof改成——isObject()能解决但是在哪改?并没有找到
5.还有说extract-text-webpack-plugin是这个插件的问题
new ExtractTextPlugin(utils.assetsPath('css/[name].[contenthash].css'))
改写成
new ExtractTextPlugin({
filename:utils.assetsPath('css/[name].[contenthash].css')),
allChunks: true
})
但是编译不过去 总是提示path.replace is not a function
还有我用的webpack1X版本 1.13.2
extract-text-webpack-plugin用的是1.0.1 一直没找到问题怎么解决!谢谢

找到原因了 因为自己用了for of Object.keys导致的
谢邀。
遇到这种问题都比较蛋疼,在使用工具时候,经常遇到莫名其妙的错误,自己代码没问题,却费了大劲在调试插件与工具上面,蛋蛋的忧伤……
讲真,我还没碰到过这种问题…… 无论是打包vue还是react。
第一张图中说
moduleId
是undefined,估计是某个模块没有被编译进来。第三张图中说
path.replace
不是一个函数,那path可能不是一个string
。这种问题,我也只能建议,无法一针见血指出是哪里出了错。
所以还是先仔细检查下你的webpack配置,最好把你的配置也贴出来,让大伙都瞧瞧。
也或许是你某个地方因为马虎导致了错误……
