打开vue项目出现` Cannot read property 'cssSourceMap' of undefined`

Question

期末了，学校要求每个人都要做一个后端管理系统。于是我屁颠屁颠的把之前项目关掉跑去做完了后台管理系统。结果，就在刚刚，打开之前写的代码就发现出现了这个问题……

TypeError: Cannot read property 'cssSourceMap' of undefined

之前在写后台管理系统的时候也出现过这种情况，后来重新又写了一遍就没问题了。好奇怪啊……我好像没对他干什么啊……

有哪位大佬知道这是怎么回事嘛？谢谢~

Answer 1

要把你webpack配置贴出来才行

Answer 2

太晚了，不知道你需要不。 错误原因是再配置请求的inde.js 中 assetsPublicPath这个地方
