CMIIW, Nim folder is self contained. @jzakiya, very likely you already have Nim installed from package manager, and its installation done like usual any package.
If you put the path in front of `$PATH`, it'll solve your problem. $ export PATH=~/nim-0.17.0/bin:$PATH In your case, you put the nim path at the end so the executable couldn't be reached because there's other nim executable at front.
