Invalid name: "@angular/cli" when do npm install

$sudo npm install -g @angular/cli

But I got the following error

npm ERR! Darwin 16.7.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "-g" "@angular/cli"
npm ERR! node v6.6.0

Somehow it looks weird as I configured angular/cli in package.json, but it result from npm version is outdated, so I did the npm update

$sudo npm update npm -g

Also the following commands can help check versions and do a clean install via "uninstall -> clean -> install".
$npm --v
$node -v
$sudo npm uninstall -g angular-cli
$sudo npm cache clean
$sudo npm install -g angular-cli@latest
