Npm '；构建'；无法识别为内部或外部命令-使用ElectronJS/electron builder

我最近与electron builder一起将我的electronJS应用程序更新为更高版本。 我在运行带有“npm start”的应用程序时没有任何问题，但是当我尝试使用electron builder构建应用程序时，在运行“npm run dist”时出现以下错误：

$npm跑步区

myapp@1.0.0地区C:\Projects\myapp 建造

“构建”未被识别为内部或外部命令，可操作 程序或批处理文件。npm错误！代码ELIFECYCLE npm ERR！errno 1 npm 犯错误myapp@1.0.0距离：

更新后，我在package.json中遗漏了以下内容：
