如何使用寶石發生器卡特爾軌道

Question

我想爲我的rails項目使用carter gem。我如何使用gem來生成預製的控制器，視圖和模型？有卡特沒有文件，所以我的嘗試是試圖rails g carter和rails g carter:install，兩者返回以下：

from bin/rails:4:in `<main>' 

所以兩個問題：是我的命令正確的，如果是的話，那麼我該怎麼辦開始解決上述錯誤（以及上述錯誤是什麼？依賴關係？）？如果我的命令不正確，那麼從寶石，特別是卡特生成M和V以及C的正確方法是什麼？

Answer 1

我知道這有點偏離正軌，但你真的不想要兩年內沒有碰過的寶石。

考慮follwing代替：

• Spree
• ror_ecommerce
• 支付爲Shopify
