Ruby 错误意外行和意外关键字结束

Question

我有一个 ruby 代码，它假设阅读一段并找出字符、单词和句子的总数，然后找到 ARI（自动可读性指数）并确定哪个年级。 我这里有代码，但是当 运行 出现这两个错误时，这是​​我第一次使用 ruby，所以我不太熟悉它的错误。

这是代码

    def calcARI(paragraph)

      file = File.open(paragraph,"r")

      if file

        file_data = file.read

        file.close

        charCount=0

        wordCount=0

        sentenceCount=0

        ARIvalue==0

        gradeLevel=""

        file.each_line { |line|

            charCount+=line.size

            for i in 1..line.length

                if(line[i]=='.')

                    sentenceCount+=1

                end

                if(line[i]==' ')

                    {

                        wordCount+=1

                    }

                end

            end

            

        }

        ARIvalue==4.71*(charCount/wordCount)+0.5*(wordCount/sentenceCount)-21.43

        case ARIvalue

        when 1

            gradeLevel="5-6 Kindergarten"

        when 2

            gradeLevel="6-7 First/Second Grade"

        when 3

            gradeLevel="7-9 Third Grade"

        when 4

            gradeLevel="9-10 Fourth Grade"

        when 5

            gradeLevel="10-11Fifth Grade"

        when 6

            gradeLevel="11-12 Sixth Grade"

        when 7

            gradeLevel="12-13 Seventh Grade"

        when 8

            gradeLevel= "13-14 Eighth Grade"

        when 9

            gradeLevel= "14-15 Ninth Grade"

        when 10

            gradeLevel= "15-16 Tenth Grade"

        when 11

            gradeLevel= "16-17 Eleventh Grade"

        when 12

            gradeLevel= "17-18 Twelth Grade"

        when 13

            gradeLevel= "18-24 College student"

        when 14

            gradeLevel="24+ Professor"

        end        

        puts "Total # of Charecter: #{charCount}"

        puts "Total # of words: #{wordCount}"

        puts "Total # of sentences: #{sentenceCount}"

        puts "Total # of Automated Readability Index: #{ARIvalue}"

        puts "Grade Level: '#{gradeLevel}''"

    else

        puts "Unable to open file!"

    end

  end

这里是错误

    main.rb:37: syntax error, unexpected '\n', expecting =>
...                   wordCount+=1
...                               ^
main.rb:128: syntax error, unexpected keyword_end, expecting '}'

Answer 1

删除 wordCount+=1

周围的大括号
