你能告诉我为什么我在混音中出现关于坚固性的错误消息吗

Question

from solidity:

simplestorage.sol:14:3: DeclarationError: Identifier already declared.
people[] public people;
^--------------------^
simplestorage.sol:9:3: The previous declaration is here:
struct people {
^ (Relevant source part starts here and spans across multiple lines).

是什么意思

Answer 1

可能是大小写的问题。

请在创建people结构时检查您将其命名为"people"或"人民。您可能将您的结构命名为"people"。在这种情况下，代码应该如下所示:

People[] public People;
