在vite.config.ts的加上下面这个也不行

build: {
 target: "es2019",
 brotliSize: false,
 chunkSizeWarningLimit: 2000
}

回答：

await 功能一般都是配合写在 async 函数里的。
Top-level await 是个新特性，没有在你的 build target 里实现，所以会报错。

回答：

错误告诉你 Top-level await is not available in the configured target environment ("chrome87", "edge88", "es2019", "firefox78", "safari13.1")

人家没骗你，看下图，真的不支持嘛
