每当我使用“ionic serve”启动Ionic应用程序时，我都会收到此错误

npm ERR! Make sure you have the latest version of node.js and npm installed.
npm ERR! If you do, this is most likely a problem with the ionic-hello-world package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR! ionic-app-scripts watch
npm ERR! You can get information on how to open an issue for this project with:
npm ERR! npm bugs ionic-hello-world
npm ERR! Or if that isn't available, you can get their info via:
npm ERR! npm owner ls ionic-hello-world
npm ERR! There is likely additional logging output above.
我删除了node_modules并完成了'npm install'。 我已经更新了Node npm和Ionic并卸载并重新安装它们。
我似乎无法在任何地方找到答案，我相信这可能是因为Sierra的升级，但似乎没有其他人遇到同样的问题
