红宝石koans shuffle发生了什么

Question

无法找出ruby koans这一个。也许有人可以帮忙？ The answers you seek... undefined method to_a_shuffle”为1..5：范围

请在下面的代码默想： /Users/nicholaskelly/koans/koans/about_dice_project.rb:12:in roll' /Users/nicholaskelly/koans/koans/about_dice_project.rb:24:in test_rolling_the_dice_returns_a_set_of_integers_between_1_and_6'`

，这里是about_dice_project .rb12：

@values = (1..number).to_a_shuffle 

Answer 1

没有名为to_a_shuffle的方法。您需要将to_a应用于范围然后shuffle该数组。

@values = (1..number).to_a.shuffle
