The above error occurs due to the fact that markdown-it-anchor has released v2.7.0 which introduces some breaking changes.

The following works fine:

`-- grunt-aglio@0.4.1
  `-- aglio@2.2.1
    `-- aglio-theme-olio@1.6.3
      `-- markdown-it-anchor@2.5.0

v2.6.0 works fine, too.

But this new v2.7.0 fails.

└─┬ grunt-aglio@0.4.1
  └─┬ aglio@2.2.1
    └─┬ aglio-theme-olio@1.6.3
      └── markdown-it-anchor@2.7.0

Some clever people here at aglio didn't care enough to set the exact version requirement in its package.json.

Please, always use the exact version.

This can be addressed by bumping to a current markdown-it, see #320.
