Summary

During install I get a permissions error on the gem folder
You don't have write permissions for the /var/lib/gems/2.7.0 directory.
I suspect it's due to the Kali 2020 switch from defaulting to root user

Expected Behaviour

install script runs correctly

Actual Behaviour

...
[INFO]  Detecting Ruby environment...
[INFO]  Ruby version 2.7.1 is installed
[INFO]  Updating rubygems...
Updating rubygems-update
Fetching rubygems-update-3.1.4.gem
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.7.0 directory.

Steps to Reproduce

New install of Kali 2020.1
run install script

You need to root privileges to install gems (unless you're using a Ruby version management tool such as rvm or rbenv). You can gain root privileges with su or sudo.

The installer should probably be updated to use sudo.

[DeezyE]

sudo in the install script is a good idea. Will do!

@jcrew99 I believe this was solved in #1940. Closing.
