          Local version 4.0.0


I try many ways to solve this error, but no one is work. I really want to know how to solve this problem!
before I ask this question, I have tried ```npm cache clear --force rm -rf node_modules npm install```,it not work for me, too. I also used root to run these command above, but it not work.
