我收到說RB此錯誤消息:10:在「活動」:主未定義的局部變量或方法「beach_bum」:對象未定義的局部變量或方法主要:對象<NameError>爲Ruby
我通過輸入活動來調用方法/函數,我不確定我在這裏錯過了什麼?我的代碼列在下面。
def activities
puts " Hi, groupFish friends, you are in Beautiful San Diego Today."
puts "Do you want to check out La Jolla Beach swipe left or check out Coachella swipe right?"
puts "There are 25 things that are happening within 5 miles!"
print ">"
choice = $stdin.gets.chomp
if choice == "left"
beach_bum
elsif choice == "right"
coachella
else
puts "Keep on swiping and be sure use the search hashtag feature to find activities!"
end
end
活動
def beach_bum
puts " Tera and John are here watching the seals, care to join?"
puts " Do you want to meet them? Y or N."
choice= $stdin.gets.chomp
if choice == "Y"
puts "Great, we'll see you at the cove in 15 minutes."
exit(0)
elsif choice == "N"
puts " Keep swiping, there's rock climbing nearby"
else puts " Jamba Juice is having a free smoothie before 2pm, it's 2miles away"
end
end
def coachella
puts " Heck Yeah, you are about to enter one of the biggest concerts of all time"
puts " There are a total of 10,000 party goers today"
end
非常感謝Peter。這工作,並且我假設當我輸入coachella時不適合我。一旦我切換它的工作!另外,我不確定我是否理解這個邏輯,爲什麼命令很重要?我首先調用了活動函數,以便按照該順序運行。 –
訂單很重要,因爲Ruby無法在未來進行時間旅行。如果方法在你調用的時候沒有定義(即使不存在),那麼Ruby應該如何執行它不知道它是什麼以及哪些不存在的東西? –
@JörgW Mittag ThnxJörg,我在回答中已經說得更清楚了 Nathan,你能接受答案嗎?將來,當您發佈代碼時,請使用{}按鈕對其進行正確格式化 – peter
