When I try to install wp-stage-switcher via Composer, I receive this error:
Your requirements could not be resolved to an installable set of packages.
Problem 1
- jeremykendall/php-domain-parser 1.3.1 requires ext-curl * -> the requested PHP extension curl is missing from your system.
- roots/wp-stage-switcher 2.0.0 requires jwage/purl ^0.0.6 -> satisfiable by jwage/purl[v0.0.6].
- jwage/purl v0.0.6 requires jeremykendall/php-domain-parser 1.3.1 -> satisfiable by jeremykendall/php-domain-parser[1.3.1].
- Installation request for roots/wp-stage-switcher 2.0.0 -> satisfiable by roots/wp-stage-switcher[2.0.0].
The installation instructions makes no mention of these. Should I install them separately and if so how?
