i ｢wdm｣: Compiled successfully.

已经显示成功编译，但是运行后页面显示却是这样：

环境：
node.js @8.11.1
webpack @4.5.0
npm @5.3.0

已经各种百度均无果，关键是同样的配置同样的代码，同事那边就可以显示正常的页面。。。实在找不到原因。求各位帮助！

Answer 1

Webpack4.x 其实你不用配 output 了，加上 publicPath 再试下。

output: {
+    publicPath: '/',
},

Answer 2

webpack4+没有看过 但是你这个问题我觉得应该是出在项目入口 或者项目出口问题 你好好找一下

Answer 3

问题已经解决了，我把项目clone到另一个文件夹下就OK了。。。难道是之前的文件名有空格的原因吗。。。不过还是感谢各位的解答！

Answer 4

我也出了这个问题，clone任何地方都不行，这是个啥情况啊？
