Yarn install issue on Mac
After trying to install Yarn from command line:
$ brew update
$ brew install yarn
Warning: Building gcc from source:
The bottle needs the Xcode CLT to be installed. xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun Error: gcc cannot be built with any available compilers. Install GNU's GCC brew install gcc
After researching, I need to install the latest xcode command line tools.
$ xcode-select --install
Then I was able to run Yarn install
$ brew install yarn
