[[Vue warn]: Error in render: "TypeError: date.getFullYear is not a function"

这个错误通常表示你正在尝试在一个非 Date 对象上调用 getFullYear 方法。请确保你的 date 变量是一个有效的 Date 对象。

如果你通过某种方式传递了一个非 Date 对象，并且希望将其转换为 Date 对象，你可以尝试使用 Date 构造函数进行转换。例如：

let date = new Date(yourNonDateObject);

如果你确定 date 变量已经是一个 Date 对象，但仍然遇到此错误，那么可能是因为你的 date 对象被修改或传递了一个不正确的值。请检查你的代码，确保传递给 getFullYear 方法的 date 对象是有效的。
