After running "gem install ffi" and trying to install it on MacOS, am getting the following error:

I have trying this solutions as well:
But still no solution.
Any ideas?
The relevant error in your log is:
/bin/sh: /Applications/Xcode: No such file or directory
This is caused by:
clang: error: no input files
cd "/Users/myuser/.gem/gems/ffi-1.12.2/ext/ffi_c/libffi-x86_64-darwin18" && /Applications/Xcode 10_3.app/Contents/Developer/usr/bin/make
The makefile for ffi probably doesn't support spaces in the command-line tool's path. You should rename your Xcode name and make sure xcode-select -p points to the updated path without spaces.
This answer might not be relevant to you anymore, but it took me quite some time to notice this in the log. I'm posting so that anyone with the same issue stumbling on this question can find an answer!
