"IndentationError: expected an indented block" in my python code

Question

好的，所以我尝试了运行我的代码（到目前为止），它有这个 annoying/weird 错误。我已经仔细检查过它，但它仍然是错误的。我知道这通常与缩进有关，但一切似乎都井井有条。我会把整个代码贴在那里。 PS 有些东西有主题标签，因此不活跃 - 它们是评论。

将第 23 - 30 行中的注释替换为 pass 关键字（或仅在注释后添加）。 if 条件的主体不能为空。 pass 充当稍后要实现的代码的占位符。

像这样：

def main():
  ch = input("")
  if ch == "1":
    #1()
    pass
  elif ch == "2":
    #2()
    pass
  elif ch == "3":
    #3()
    pass
  elif ch == "4":
    #4()
    pass
  elif ch == "5":
    exit()
  else:
    setup_main()
