What to do if the debug gem installation fails

When I was building a ruby environment on a Macbook Pro 13 inch (2020 model), I stumbled upon installing a debug gem.

Environment executed this time

Catalina 10.15.4

Introducing Gem for debugging

Introduce a gem for debugging via bundler.

python


$ gem install bundler
$ bundle init
$ gem install debase
$ gem install ruby-debug-ide

I throw an error.

python


uilding native extensions. This could take a while...
ERROR:  Error installing debase:
        ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib
        --with-make-prog
        --without-make-prog
        --srcdir=.
        --curdir
        --ruby=/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/$(RUBY_BASE_NAME)

        --without-ruby-include=${ruby-dir}/include
        --with-ruby-lib
        --without-ruby-lib=${ruby-dir}/lib

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

  /Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/debase-0.2.4.1/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.6.0/gems/debase-0.2.4.1 for inspection.
Results logged to /Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/debase-0.2.4.1/gem_make.out

Upon examination, it seems that debase-ruby_core_source and ruby version 2.6.3 are inconsistent. Therefore, I changed the version of ruby.

python


$ brew update
$ brew install rbenv
$ rbenv --version
  rbenv 1.1.2
$ rbenv install 2.6.6
$ rbenv global 2.6.6

You can now safely install the debug gem.
