javascript - 无法启动离子应用程序

问题描述

升级节点和 npm 后，我无法启动旧的 ionic 应用程序，这是错误：

± |master U:1 ?:1 ✗| → ionic serve

> ionic-hello-world@ ionic:serve /Users/John/Dropbox/www/salon-app
> ionic-app-scripts serve "--v2" "--address" "0.0.0.0" "--port" "8100" "--livereload-port" "35729"

我试过删除node_modules，npm install但没有运气。

//LE 运行后npm audit显示某些包有问题，我正在尝试更新这些包

解决方案

在删除node_modules并重新安装 ionicnpm install -g cordova ionic并运行npm audit以查看哪些软件包被破坏后，它再次工作。

我不确切知道修复了什么，但我重复了这个过程并且它有效。
