【问题描述】：

在我的应用程序中，我正在使用 spree gem。现在对于产品导入，我使用了 spree_import_products gem。

first i add "gem 'import_products', :git => 'git://github.com/joshmcarthur/spree-import-products.git'

然后在gem文件中捆绑安装”。然后运行捆绑安装，它成功安装。然后运行“rake import_products：install”。但它显示错误像这样......

【解决方案1】：

您可以检查here，此扩展需要非常旧的 Spree 和 Ruby 版本。它没有测试。问题在于扩展本身。寻找另一个扩展或自己实现。
