这段代码应该可以工作。但是每次我在 Ruby 上打开它时，Ruby 几乎都会立即关闭，因为它无法读取代码中的某些内容。所以很明显代码中有一个错误，但我查看了所有内容，似乎找不到它。我需要一些帮助才能使此代码正常工作。非常感谢您！

puts 'Enter the number of the current month using the 12 months per year scale. Ex. January would be 1, February would be 2, March would be 3, etc...'
month=gets.chomp
case month
when '1'..'3'
fee='$45'
when'4'..'5'
fee='$55'
when'7'..'8'
fee='$65'
else
fee='$0.00'
end
puts'The fee to apply for the competition is ' + fee + '.00 when you apply on the date of today, ' + Time.now.to_s +'.'
puts 'If your fee came up as $0.00, then that is because the competition has ended. But do not worry, there is always next year!'
sleep 20

这就是 Ruby 告诉我的语法错误：

temp.rb:13: syntax error, unexpected tUPLUS, expecting $end
... of today, ' + Time.now.to_s +'.'

+在和之间添加空格'.'可修复语法错误。

您可以通过从命令行运行 Ruby 自己解决这个问题。我假设您正在运行 Windows。要进入命令提示符，您可以按Windows key和R打开运行对话框。从那里，您可以输入cmd并按下enter以打开命令提示符。然后，您可以使用cd更改当前目录并ruby运行您的 Ruby 脚本（假设 Ruby 在 中PATH）。您的会话可能如下所示：

C:\Documents and Settings\Madelyn Grewal> cd Desktop

C:\Documents and Settings\Madelyn Grewal\Desktop> ruby myscript.rb
myscript.rb:13: syntax error, unexpected tUPLUS, expecting $end
... of today, ' + Time.now.to_s +'.'

C:\Documents and Settings\Madelyn Grewal\Desktop>
