Vue create reports an error

Solution: https://stackoverflow.com/questions/53934852/vue-cli-3-command-failed-npm-install-loglevel-error

It should be noted that the article provides two main solutions:
1. NPM cache clean -- force or manually delete the NPM cache in the appdata folder
2.npm config set registry=" http://registry.npmjs.org/" after running this command, you can create your own project.

After I tried the first scheme unsuccessfully, I tried to combine the two schemes successfully, but I don’t know the specific principle. I hope someone with good intentions can help me solve what’s wrong
