原因:新版的webpack-dev-server 3.1.14 存在问题。

解决方法:package.json 中指定 webpack-dev-server 低版本号

方法1:

“webpack-dev-server”: “^2.9.1”

删除 node_modules 目录,再重新安装依赖包

npm install -S // 这种方式安装的时间会长些,也可以只重装 webpack-dev-server模块

**方法2:**单独重装 webpack-dev-server模块

(1)npm uninstall webpack-dev-server

(2)npm install webpack-dev-server@2.9.1

(3)npm run dev

**方法3:**单独重装 webpack-dev-server模块

删除node_modules ,重新npm install 然后 npm run dev
