我在我的大禮包中使用spree_multi_currency gem https://github.com/pronix/spree-multi-currency。它工作，但是當我添加產品到購物車當時它給錯誤，如Spree多種貨幣
undefined method `target_shipment=' for #<Spree::Variant:0xb4ea7b80>
def add_to_line_item(line_item, variant, quantity, currency = nil, shipment = nil)
if line_item
line_item.target_shipment = shipment
line_item.quantity += quantity.to_i
line_item.currency = currency unless currency.nil?
else
.......
end
這裏是我的全部跟蹤

在此先感謝。
你可以添加一個完整的堆棧跟蹤？不確定target_shipment來自哪裏，能夠幫助您解答問題。 – GeekOnCoffee
