prerender 功能仅支持有效 JavaScript 的子集 — 请务必使用 export const prerender = true，以便我们的编译器可以在构建时检测到此指令。不支持变量、let 和 var 声明。

¥The prerender feature only supports a subset of valid JavaScript — be sure to use exactly export const prerender = true so that our compiler can detect this directive at build time. Variables, let, and var declarations are not supported.
