Hi:
After I updated macOS Catalina, Markdown Preview no longer works. I got the following error message:
Please install the Redcarpet and Pygments.rb RubyGems by running the following: /usr/bin/gem install --user redcarpet pygments.rb
After I ran the above command, I received the following error message from the Terminal:
$ /usr/bin/gem install --user redcarpet pygments.rb Building native extensions. This could take a while... ERROR: Error installing redcarpet: ERROR: Failed to build gem native extension.
current directory: /Users/tzha/.gem/ruby/2.6.0/gems/redcarpet-3.5.0/ext/redcarpet /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/ruby -I /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0 -r ./siteconf20191111-836-11oqvm2.rb extconf.rb mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/include/ruby.h
You might have to install separate package for the ruby development environment, ruby-dev or ruby-devel for example.
extconf failed, exit code 1

Can someone help me to resolve this issue?
Thanks,

I'll tell you that what I would do first would be to make a new file and paste in:
gem install --user redcarpet pygments.rb
Then run that line from within TextMate using Bundles -> Shell Script -> Execute line.
[You can also find it by pressing ⌘ + T and searching for "Execute line" or by pressing ^ + R.]
That way you can be relatively sure that the `gem` that TextMate runs commands with will be the one used to install pygments.
Thanks, Graham
