意外的关键字结束错误，但语法似乎很好 [英] Unexpected keyword_end error, yet syntax seems fine

问题描述

这个函数应该从逗号分隔值文件中提取名称，并将它们放入一个数组中.

This function is supposed to pull names from a Comma Separated Values file, and place them into an array.

def xprt_csv_to_ary(csv_file)
    namecatcher_regex = "/^[\.{1}]([A-Z]+)\.{3}/" # Matches up to char before next name
    current_word = 0
    names_array = []
    while current_word < 5000
        if current_word == 0
            name = csv_file.readline.match(namecatched_regex)
        else
            name = csv_file.past_match.match(namecatcher_regex)
        end
        names_array[current_word] = name
        current_word ++
    end
    return names_array
end

我收到以下错误:

syntax error, unexpected keyword_end

如果有人直接回答我，我会很高兴被提及解决我的问题的现有问题.

I would be as happy to be referred to an existing question that solves my problem as to have someone answer me directly.

推荐答案

您的错误来自行:

current_word ++

Ruby 中没有这样的语法.应该是:

There's no such syntax in Ruby. It should be:

current_word += 1

此外，您错误地创建了正则表达式.应该是:

What's more, you create your regexp incorrectly. It should be:

namecatcher_regex = /^[\.{1}]([A-Z]+)\.{3}/

可能还有一些我没有注意到的其他错误.

There may be some other errors that I didn't notice.
