Hi,

I am attempting to install ZAT by following the steps here: https://developer.zendesk.com/documentation/apps/zendesk-app-tools-zat/installing-and-using-the-zendesk-apps-tools/

I am installing on a Macbook Pro 2020 (w/ M1 chip) - I am installing against an alternate version of Ruby from the system default (v3.0.2). The latest version of xCode CLI is also installed.

However, ZAT is failing to install, when it reaches the nokogiri gem - the error I am getting is:

gem install zendesk_apps_tools
Building native extensions. This could take a while...
ERROR: Error installing zendesk_apps_tools:
ERROR: Failed to build gem native extension.

IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.10
with the following patches applied:
- 0001-Revert-Do-not-URI-escape-in-server-side-includes.patch
- 0002-Remove-script-macro-support.patch
- 0003-Update-entities-to-remove-handling-of-ssi.patch
- 0004-libxml2.la-is-in-top_builddir.patch
- 0005-Fix-infinite-loop-in-xmlStringLenDecodeEntities.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

gem install nokogiri -- --use-system-libraries
[--with-xml2-config=/path/to/xml2-config]
[--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

bundle config build.nokogiri --use-system-libraries
bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

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

/Users/sf/.gem/ruby/3.0.2/extensions/arm64-darwin-20/3.0.0-static/nokogiri-1.10.10/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /Users/sf/.gem/ruby/3.0.2/gems/nokogiri-1.10.10 for inspection.
Results logged to /Users/sf/.gem/ruby/3.0.2/extensions/arm64-darwin-20/3.0.0-static/nokogiri-1.10.10/gem_make.out

I can install the latest version of nokogiri (1.11.7 arm64-darwin), however the version being installed via ZAT is 1.10.10. If I attempt to install that gem directly, I get the same error.

Any assistance on getting this working, would be greatly appreciated.

Best regards,
Stephen
