Installing Cordova not accepting my password

I am trying to install Cordova to make another start at building a mobile app. NodeJS is already installed but it then says Cordova needs installing and asks me for my password. I keep entering my Mac password but it isn’t accepting it. After three attempts it bombs out.

I then tried to install it through the terminal (I’m on a Mac) using this command:

sudo npm install cordova

which seems to have worked fine (this accepted my password) but Wappler still says it’s not installed. I’ve restarted Wappler multiple times, too (v3 Beta 1).

Help!
