我 ruby 是 1.8.7 的，所以哈希就不能用：了，也懒得优化你的代码了，直接拷贝直接改。。。还好你不是我带的。。。不然非骂一顿

#1 楼 @help5305fff black_jack.rb: 1: syntax error, unexpected tIDENTIFIER, expecting $end puts "=>Hello, ...er1 name." 请问这是哪里出错了？

你那提示是说的代码少了结束的标签

#3 楼 @help5305fff 我找不到哪里少了 end 阿。。

你把我写得覆盖进去，也会提示那错误？

#5 楼 @help5305fff 没有，不过我想知道我原来的哪里少了 end。

不一定是 end { 少了} ( 少了) 都会提示这个哈

我把你的复制下来运行，没有发现你说的错误，倒是有两个变量定义错误。

我也没出现他说的错误。。。

#8 楼 @yangyanhao 我改了那两处还是不行。。。还是老样子

#9 楼 @help5305fff #8 楼 @yangyanhao 奇怪了

你覆盖我帮你改的代码，看看有错没呢？大哥，你做人真累。。。 要让人帮忙，又不愿管别人的说法。。。

如果覆盖我的代码还是有错，那就有可能是编码的错误。。。你不去试，就是在浪费生命。。。苦恼的都是一些旁支细节，不抓重点。。。

我只改了两处，就顺利运行了：

player1_cards -> player1_card player2_cards -> player2_card

=>Hello, please enter player1 name.

=>Hello, please enter player2 name.

=>hello and , let's play the black jack game. =>Player One's first card is: 5, second card is 4, total is 9. =>Player Two's first card is: 2, second card is 10, total is 12. => Player Two won!!

#13 楼 @help5305fff 果然还是错误

检查编码

#16 楼 @help5305fff UTF-8 。。。。。。

解决了吗？？？

#16 楼 @help5305fff 还没。。是不是要改成 ASCII？

#18 楼 @help5305fff 我复制了代码，另外新建了一个文件可以运行了。请问这个问题应该怎样解决啊？原来的代码我是用个 iphone 上的软件写的。 #13 楼 @help5305fff 受教了。;-) 谢谢

。。。。那就是编码问题了

#21 楼 @help5305fff 应该改成什么呢？

啥正确就换啥，哈哈

不懂。。。
