During the install https://github.com/laravel/spark I kept getting this error

Finally I went into my ~/.composer folder. Removed composer.lock then I edited the composer.json to look like this

{
    "require": {
        "laravel/envoy": "~1.0",
        "laravel/installer": "~1.1",
        "laravel/spark-installer": "~1.0"
    }
}

I use Envoy for a lot of my projects so I left that there and made sure to update my installer.

Then I ran, in that folder composer update.

Finally I made sure to add the path to my ~/.bash_profile as

export PATH=$PATH:/Users/alfrednutile/.composer/vendor/bin/

Then ran source ~/.bash_profile

With all that in place I could go to my new Laravel install to run spark install
