You need framework7-cli to be installed globally to your PC

First of all make sure you have latest stable Node.js and NPM installed on your machine.

If you are going to target Native/Hybrid apps then you also need to install Cordova first (may require sudo):

$ npm install -g cordova

Now we can install Framework7 CLI (may require sudo):

$ npm install -g framework7-cli

If you have issues with installation related to access errors, you may try to run the command with additional flags:

$ npm install -g framework7-cli --unsafe-perm=true --allow-root
