Inspect or clean up the working tree error when installing Ruby 2.1.3 on Mac OS X 10.9.5

Question

I'm trying to install Ruby 2.1.3 on Mac OS X 10.9.5 using the rbenv install 2.1.3 command. However I get the error message below. I tried every suggestion on stack overflow and elsewhere. Nothing seems to be working. I currently have the original ruby version that came with 10.9.5, Ruby 2.1.3p242. Brew doctor says everything is fine and rbenv is up to date. Thanks so much! Trying to learn Ruby and Ruby on Rails but I can't get passed this stage.

I have a m1 mac and I also got this error installing ruby, this command worked for me:

export optflags="-Wno-error=implicit-function-declaration";

run this and then try rbenv install again.

Did you try this:

CC=/usr/bin/gcc rbenv install 2.1.3
