Cannot Install Nim

[joe_04_04]

A little bit of background. I'm running macOS 10.14.6 currently. I have had Nim 
installed in the past as well, but I don't recall the version number. I did 
manually remove Him at one point, deleting .choosenim and .nimble from my Mac 
home directory. Now, I'm trying to reinstall Nim using; curl 
https://nim-lang.org/choosenim/init.sh -sSf | sh, but I keep getting errors 
when I do:
    
    
    curl https://nim-lang.org/choosenim/init.sh -sSf | sh

I'm not sure why the Nim error is reporting a missing .h file. I've been trying 
to solve this for multiple days now with no luck. Any help would be greatly 
appreciated. Thank you.
