If webpage gives you "No input file specified." this means your project directory is not properly mounted to homestead.
first check your homestead.yaml file so it is properly formatted and has both:
folders:
- map: C:/your_project_root_directory
to: /home/vagrant/Code
and also there should be a right settings for your nginx virtual host section
sites:
- map: homestead.app
to: /home/vagrant/Code/public
If your directories are different adjust accordingly.
After this settings checking you need to vagrant up --provision
It'll update your vagrant box configuration as you've specified in Homestead.yaml
this file usually placed in ~/.homestead/Homestead.yaml
~ means home directory on windows it is C:\Users\Your_UserName\
after you'll provision your box make vagrant halt again and vagrant up
after this you can check if your development box accessible. To ensure you've set up path mappings correctly you can log in to your box via ssh and check contents of /home/vagrant and subdirectories
Note: yaml files doesnot allow tab spaces! only usuall spaces edit it in editor like Notepad++ which could show you unprintable characters so you'll not break your yaml file.
