无法全局安装包

Question

Hi whenever I try to install or run a command globally using npm my terminal always displays an error of the following:

Does anyone know why? I was trying to install ionic earlier using the $ npm install -g @ionic/cli command but it wasn't working but as soon as I removed the -g it seemed to download perfectly, I would like to know the cause.

Thanks,

If you are on Linux or MacOS try:

$ sudo npm install -g @ionic/cli

Instead of:

$ npm install -g @ionic/cli
