Webpack npm ERR缺少脚本：build; （WINDOWS 10）

Question

我和我今天在学校期间正在制作ha句检查员。一切都很好，但当我克隆他的回购时，我得到了一个＆＃34; npm ERR！缺少脚本：构建;＆＃34;在我的Windows 10 PC上

我们非常感谢任何帮助，我可以提供更多信息

其他错误

npm ERR! Haiku@1.0.0 start: `npm run build; webpack-dev-server --open --mode development`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the Haiku@1.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

这是我的package.json
