Bumps nokogiri from 1.6.6.2 to 1.9.1. This update includes security fixes.
Vulnerabilities fixed

> **Moderate severity vulnerability that affects nokogiri**
> The xz_head function in xzlib.c in libxml2 before 2.9.6 allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file.
