'ionic serve‘和'npm run ionic:serve’都不工作

Question

我正在尝试在本地主机上运行Ionic 3应用程序，一开始我使用的是命令

ionic serve

它是工作的，直到它突然停止，我不知道原因，我寻找了很长时间，直到我找到一个替代命令

npm run ionic:serve 

它工作了一个星期，然后停止了，现在我真的不知道该怎么做，我不能测试任何应用程序，请帮助

这是'npm run ionic:serve‘的结果。

我在网上尝试了所有可能的解决方案，我甚至尝试删除node.js和ionic，然后重新安装它们，但都不起作用。请帮帮忙

Answer 1

尝试运行npm cache clean -force。这应该可以工作，如果它不尝试重新安装节点，并再次执行npm安装
