解决了吗？

"cross-env": "^5.1.6",

"css-loader": "^0.28.11",

"file-loader": "^1.1.11",

"html-webpack-plugin": "^3.2.0",

"style-loader": "^0.21.0",

"stylus": "^0.54.5",

"stylus-loader": "^3.0.2",

"url-loader": "^1.0.1",

"vue": "^2.5.16",

"vue-loader": "^14.0.3",

"vue-template-compiler": "^2.5.16",

"webpack": "^4.10.1",

"webpack-cli": "^2.1.4",

"webpack-dev-server": "^3.1.4"

复制后重新npm install

好像是webpack和vue-loader的版本问题

很奇怪

降低webpack-cli版本到1.5.3

大佬解决了吗

我怎么发不来问题啊？？只能回复别人的。

npm install -D webpack-cli
