.babelrc

{
  "plugins": [
    "babel-plugin-transform-vite-meta-env"
  ],
  "presets": [
    "@vue/babel-preset-jsx",
    [
      "babel-preset-vite"
    ],
    [
      "@babel/preset-env",
      {
        "targets": {
          "node": "current"
        }
      }
    ]
  ]
}

If there is more than one, an error will be reported

What should I do to avoid this mistake I hope it can be compiled normally
