Question

我正在运行一个教程，即使我完全按照指示输入了这个代码，但它会返回语法错误。任何人都可以解释如何在ruby中创建一个段落吗？

我的尝试如下所示。

由于

Puts <<PARAGRAPH
There's something going on here.
With the PARAGRAPH thing.
We'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.
PARAGRAPH

Answer 1

你有Puts。你想要puts。

Answer 2

将它设为method of module Kernel，您应该用小写字母写puts

Answer 3

original tutorial有puts，而不是Puts：

# Here's some new strange stuff, remember type it exactly.

days = "Mon Tue Wed Thu Fri Sat Sun"
months = "Jan\nFeb\nMar\nApr\nMay\nJun\nJul\nAug"

puts "Here are the days: ", days
puts "Here are the months: ", months

puts <<PARAGRAPH
There's something going on here.
With the PARAGRAPH thing
We'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.
PARAGRAPH

Answer 4

就像有些家伙所说，将"Here are the days: ", days分配给puts是你的问题。当您点击puts <<PARAGRAPH行时，解释程序会尝试将PARAGRAPH附加到数组puts，而不是生成此处的文档，但当然PARAGRAPH未定义。

注意到你实际上仍然可以强制它使用语法

，这很有趣（虽然不是很有用）

puts(<<PARAGRAPH)
Theres something going on here.
With the paragraph thing.
Well be able to type as much as we like.
Even four lines.
PARAGRAPH

Answer 5

有趣的是，你可以在这里做。你可以这样做：

<<PARAGRAPH
typing lines of data, etc
more input
PARAGRAPH

您选择的

或'任何'大写单词：

<<BUILDING
typing lines, etc
BUILDING

我用过的每一个字都有用。

Answer 6

检查PARAGRAPH末尾是否有空格。确保在PARAGRAPH之后没有空间，你很高兴。

puts <<PARAGRAPH
There's something going on here.
With the PARAGRAPH thing.
We'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.
PARAGRAPH
