How to install MySQL gem on Mac OS X

Question

What do I need to install mysql gem on Mac OS X ? I\'m getting error \"failed to build native extensions\".

Answer 1

I came across this issue while setting up MySQL gem on MacOs Mojave .This worked for me

1 Ensure Xcode command line tools are installed. xcode-select --install

2. For me the build was still failing with some header files missing which you have to install open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

This link pointed to right direction. Can't compile C program on a Mac after upgrade to Mojave
