What is your ionic info output?

Your problem is probably with npm, something to do with permissions and files. This happens quite often and is almost impossible to successfully debug (at least here in the forum).

One solution: Uninstall your node, install nvm (or nvm-windows if you are on Windows), install a new node (which includes npm) with this, then install ionic and cordova again and try your command again. The problem should be gone.

Make sure ionic and ionic CLI should be up to date. Check your system proxy is applied.
Then simply run ionic start myApp sidemenu
