免责声明：我刚刚开始使用。
我使用没有选项的rvm安装了Ruby 1.9.3。
我正在关注rails第4版的敏捷开发教程。 当我运行rails rake test：units时出现这个错误：

我不相信它与rails app本身有什么关系，可能是关于环境以及如何安装rake和ruby，可能是rvm如何安装并加载ruby？
我在没有--ggc-clang的情况下安装了xcode和Ruby（读取1.9.3不再需要该选项）
我有点迷失 - 任何帮助都会非常感激。
答案 0 :(得分：0)
正如Ruby告诉你的那样，我认为你有语法错误：
assert product.[:price].any?
应该是：
assert product[:price].any?
