Installing an R package from Github

I'm trying to install an R package (X) from Github on Spotfire, using the TERR Console.  I've loaded all the packages that X relies on through the CRAN Package Repository in TERR Tools.  However, each time I try to load in the package from Github, I'm receiving an error.  Though, I can load it in R perfectly fine.  I receive the following error message:

Downloading GitHub repo "X" from URL https: **

Installation failed:argument is of length zero


Any advice on how I can do this?

Greatly appreciate it.
