javascript - 解决失败: { Error: Cannot find module 'npm-watch'

Question

当我运行“npm install”时，它成功运行并安装了node_module文件夹中的所有包。但是，当我在 cmd 中运行“npm start”命令时，它会出现以下错误。

D:\INSM-HTML-Player>npm start
insm-player@1.0.0 start D:\INSM-HTML-Player
npm run build && npm run serve | npm run watch

您必须将缺少的包 npm-watch 添加到 package.json 中:

npm install npm-watch --save-dev

再次运行npm start。
