我使用大禮包我的購物車，我想多貨幣支持，因此我用下面的寶石在我的Gemfile施普雷輯陣匯率
gem "spree_multi_currency", :git => "git://github.com/pronix/spree-multi-currency.git"
和比沒有捆綁安裝
rake spree_multi_currency:install:migrations
rake db:migrate
然後使用以下代碼加載貨幣
rake spree_multi_currency:currency:iso4217
現在我想從谷歌加載費率，並使美元作爲默認貨幣CY 爲我鍵入它在終端
rake spree_multi_currency:rates:google[USD]
，但它給錯誤，如
Loads currency data from Google using #<Spree::Currency:0xb967020>
