Instead of a standard WordPress install, you can install it with Bedrock by Roots. It is a boilerplate that uses the standard WordPress install and provides a better folder structure to accommodate different environments. Use the commands below
composer create-project roots/bedrock
Navigate to Wordpress Admin > Plugins > Search for WooCommerce and install it.
Navigate to the newly created folder on command line
composer require flagshipcompany/flagship-for-woocommerce-bedrock:^1.0
Make sure WooCommerce is installed before installing the plugin.
Download zip file from GitHub.
Wordpress Admin > Plugins > Add New > Upload plugin > Upload the plugin zip file.
Navigate to wp-content > plugins > flagship-for-woocommerce-bedrock on command line.
composer install
