    - gloudemans/shoppingcart 2.5.0 requires illuminate/support 5.1.*|5.2.*|5.3.*|5.4.*|5.5.*|5.6.* -> found illuminate/support[v5.1.1, ..., v5.6.39] but these were not loaded, likely because it conflicts with another require.
    - gloudemans/shoppingcart 2.6.0 requires illuminate/support 5.1.* || 5.2.* || 5.3.* || 5.4.* || 5.5.*|| 5.6.* || 5.7.* -> found illuminate/support[v5.1.1, ..., v5.7.28] but these were not loaded, likely because it conflicts with another require.
    - Root composer.json requires gloudemans/shoppingcart * -> satisfiable by gloudemans/shoppingcart[1.0, ..., 1.3, 2.0.0, ..., 2.6.0].
 
You can also try re-running composer require with an explicit version constraint, e.g. "composer require gloudemans/shoppingcart:*" to figure out if any version is installable, or "composer require gloudemans/shoppingcart:^2.1" if you know which you need.
