valet: Cannot install valet, errors with symfony/process?

Hey guys,

I recently installed php 7.1.12 on my mac (high sierra), composer 1.5.5, laravel/installer, and now I’m trying to install laravel/valet to no avail. Below is the output I’m getting. Any ideas?

`composer global require laravel/valet Changed current directory to /Users/brad/.composer Using version ^2.0 for laravel/valet ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages.
