How can I solve this?

My npm v is 8.1.0. My node v is v16.13.0.

CodePudding user response：

it looks like what you need is to update your node js version, which then will also update your npm and LTS version, as it says in this article, hope it help you!.

I'm currently working on angular 8 and I'm using npm v 7.11.2 and my node js v is 14.15.1.
