Ruby:意外的输入结束，if 语句需要关键字结束 [英] Ruby: unexpected end-of-input, expecting keyword_end for if statement

问题描述

我使用 Java 工作了几个月，现在正在过渡回 Ruby.我从以下代码中收到一个奇怪的错误:

I was working with Java for a few months and am transitioning back to Ruby now. I am getting a weird error from the following code:

def count_divisors
  divisor_hash = {}
  25.times do |i|
    divisor_hash[i] = find_dividends(i)
  end
  puts divisor_hash
end

def find_dividends(i)
  count = 0
  1000.times do |k|
    if i % ( k + 1 ) == 0
      count++
    end
  end
  count
end
count_divisors()

此代码生成以下错误:

test.rb:14: syntax error, unexpected keyword_end
test.rb:19: syntax error, unexpected end-of-input, expecting keyword_end

当我删除 if 语句时不会发生此错误.我不知道为什么.我知道每个 if 语句都需要一个 end 语句，但出于某种原因，该 end 语句的位置似乎令人不安.

This error does not occur when I remove the if statement. I am not sure why. I know every if statement needs an end statement, for some reason it seems upset by the placement of that end statement though.

推荐答案

将 count++ 更改为 count += 1 Ruby 不支持增量运算符.

Change the count++ to count += 1 Ruby does not support incremental operator.
