difficulty installing RedCloth on Mac OS X (Mojave 10.14.5)

[sccarr]

Hi, I am trying to install RedCloth onto my Mac, and I've tried it a couple different ways. I've tried it with Bundler, and also just gem install redcloth, and I've also tried it with specific flags. Each time I've gotten the following error:

Building native extensions. This could take a while...
ERROR:  Error installing RedCloth:

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

extconf failed, exit code 1

Gem files will remain installed in /usr/local/lib/ruby/gems/2.6.0/gems/RedCloth-4.2.9 for inspection.

I don't think I need to install development tools - at least, I have XCode and I am pretty sure I have accepted the license.

Try enabling xcode. check if "xcodebuild -license" on command line returns the license, if not then do the following: My OS version Catalina 10.15.3

1. Install Xcode and accept terms.(if already done skip to step 2)
2. run "sudo xcode-select -s /Applications/Xcode.app/Contents/Developer"

Now "xcodebuild -license" should return agreement.

Proceed

Hi there. Thanks for reporting it. Are you still having this issue?

I am able to compile, build, and test the gem on my Mac, but I am using a much newer version.
