Hello, this help me resolve the problem for me.

Open Terminal
Install Homebrew:

 ruby -e "$(curl -fsSL https://raw.githubusercontent...)"
Do not close Terminal, open Mac Appstore and check Update, install all XCode Command Line Tools updates OR in my case, XCode Command Line Tools started install automaticly throught Terminal right after step 2.
Back to Terminal
Install Ruby:
 
brew install rbenv ruby-build
Install SASS gem: 

sudo gem install -n /usr/local/bin sass
After this steps, everything works fine and I can compilate again with Koala or in Dreamweaver.

我在github上找到解决办法了

第一步：在命令中运行ruby -e "$(curl -fsSL https://raw.githubusercontent...)"

第二步：打开你的xcode进行更新

第三步：命令中运行
brew install rbenv ruby-build

第四步：命令中运行
sudo gem install -n /usr/local/bin sass

完成后koala就能正常编译了
