VUE install - unable to resolve dependency tree-CodePudding

I pull my project from other computer, it works fine there, but when i npm install on this machine it got this error. can i have some clue about how to fix this and what I need to do to avoid this kind of problem in the future.

I've tried installing vue, update npm to v18, all requirement are supposed to be fulfilled

CodePudding user response：

You are installing ElementUI version 2.15.12 - which supports only Vue version 2 but your Vue is version 3.
Either install ElementPlus or downgrage Vue 3 to Vue 2.
