Failed to load mods: Error while running setup for recipe prototype "rf-circuit-floor-tile" (recipe): recipe item-product "green-wire" is not stackable but has a max count of 2.

I suspect this is a problem with using green wire as a component to craft (which isn't possible in space age, that I can see?)
In fact, changing
{type = "item", name = "green-wire", amount = 10},
to
{type = "item", name = "copper-cable", amount = 10},
in recipes.lua cleared the error

correction: also need to remove the line
{type = "item", name = "red-wire", amount = 10}
(and the comma at the end of the line before it)

Updated

small typo...
{type = "item", name = "copper-wire", amount = 20},
should be
{type = "item", name = "copper-cable", amount = 20},
