The steps below are steps applicable on Debian/Ubuntu systems. In my case, I installed this on Kali Linux. First, we update the system.
sudo apt update; sudo apt upgrade -y
sudo apt-get install opam
opam init
opam update
opam install google-drive-ocamlfuse
PATH='/home/kali/.opam/default/bin':$PATH; export PATH;
## Change target directory to your preference
mkdir ~/GDrive
google-drive-ocamlfuse ~/GDrive
