ERROR command failed: npm install --loglevel error

Answer 1

seems a cache error
run
npm cache clean --force
then try create the project again

Answer 2

That's weird. I'd just try re-installing the Vue cli package.
There is a deprecated vue-cli package, it could be you have that installed rather than the official one #vue/cli.
Either way just uninstall it with
npm uninstall [your-vue-cli-package] -g
Then re-install it again.
npm install #vue/cli -g

Answer 3

lets try this
$ sudo npm uninstall -g vue
$ sudo npm uninstall -g vue-cli
$ sudo npm uninstall -g #vue/cli
$ sudo npm cache clean --force
$ sudo npm install -g vue
$ sudo npm install -g #vue/cli

Solve:
check proxy at config
npm config edit
npm config --global edit
clean and set proxy
npm config set proxy null
npm config set proxy false
