Any additional comments? (optional)

文件没有在 src 目录下，目前这样没有打包出文件

import { defineConfig } from "father";

export default defineConfig({
  esm: {
    input: ".",
    output: "es",
    platform: "browser",
    transformer: "swc",
  },
  cjs: {
    input: ".",
    output: "lib",
    platform: "browser",
    transformer: "swc",
  },
  umd: {
    entry:'index.ts',
    output: "dist",
    sourcemap: true,
  },
});
