Unable to install RGB command-line tool following rgb.tech instructions

I tried to install the RGB command line tool by following the methods described on rgb.tech/install.
Unfortunately, the installation failed.
Could you please guide me on how to fix this or let me know if there are updated installation steps?

Here is a modified and tested quick startup command by me. You can give it a try. @0xdavinci
