Question

Laravel

Started installing Laravel on PC.
Delivered Virtual box and Vagrant
Further it is necessary to enter vagrant box add laravel/homestead
In what command line to enter? writes an error in cmd

Answer 1

Windows OS? If yes, then install Git and use Git Bash to execute commands.

Answer 2

varrant must be registered in PATH, try to log out and log back in.
docs.vagrantup.com/v2/installation

The installer will automatically add vagrant to your system path so that it is available in terminals. If it is not found, please try logging out and logging back in to your system (this is particularly necessary sometimes for Windows).
