推荐答案

将 package.json 中的依赖更改为

change dependency in package.json to

"webpack-dev-server": "2.1.0-beta.10",而不是像

"webpack-dev-server": "2.1.0-beta.10", Instead of something like

"webpack-dev-server": "^2.1.0-beta.9",

"webpack-dev-server": "^2.1.0-beta.9",

之后运行 npm install 或 npm update.

run npm install or npm update afterwards.
