An error occurred while installing scraperwiki (3.0.1) gem

Ran into this issue when running under ruby 2.3.x:

The scraperwiki gem installs fine under the default ruby 2.0.0.

Bundler runs fine for ruby 2.3.x on my local environment.

Thanks, you’ve found a bug: https://github.com/openaustralia/morph/issues/1001

As you say, the workaround is to select an older version of Ruby for your scraper.
