Start with npm install to download dependencies but always prompt "found 64 vulnerabilities (63 low, 1 high) in 59916 scanned packages
64 vulnerabilities require manual review. See the full report for details." Using npm audit fix is also useless. If you use npm run dev directly, you will get an error "npm ERR! code ELIFECYCLE
Npm ERR! errno 1
Npm ERR! vue-element-admin@4.2.1 dev: vue-cli-service serve
Npm ERR! Exit status 1
Npm ERR!
Npm ERR! Failed at the vue-element-admin@4.2.1 dev script.
Npm ERR! This is probably not a problem with npm. There is likely additional logging output above."
