Hi there,
today I've updated to macOS 11.0 "Bug Sure" and I instantly noticed that colorls isn't working anymore. If I try to execute/install it I get the following error:

Error code:

To see why this extension failed to compile, please check the mkmf.log which can be found here:

Do you have any idea of what can cause this error? Eventually how should I fix it?
Many thanks in advance and have a great day :D

Yep and the error is the same as the one I pasted above :'(
I'm gonna reinstall ruby-dev and let you know if this bug is solved or not

UPDATE: HOW TO FIX

I managed to get colorls working by reproducing the following steps:

• download the latest version of XCode
• Open XCode and let it install its CLI tools
• reinstall colorls and its dependencies through the following commands:

sudo gem pristine eventmachine --version 1.2.7
sudo gem pristine ffi --version 1.13.1
sudo gem pristine http_parser.rb --version 0.6.0
sudo gem pristine json --version 1.8.6
sudo gem pristine nokogiri --version 1.10.10
sudo gem pristine posix-spawn --version 0.3.13
sudo gem pristine rinku --version 2.0.6
sudo gem pristine sassc --version 2.4.0
