React native 插件/预设文件不允许导出对象，只能导出函数

将react native更新为“^0.56.0””后出现此错误：

我试着做一些类似于这里投票率最高的答案的事情，但是取而代之的是巴贝尔预设流：

什么都没用。有什么想法吗

编辑：根本没有节点模块/babel预设流文件夹

我遇到了相同的错误，通过卸载

babel预设流

并安装

@babel/preset流

解决了这个问题。我相信这是因为使用巴别塔7。并添加到

.babelrc

{
  "presets": ["@babel/preset-flow"]
}

---

升级您的babel预设以反映本机依赖关系

"babel-preset-react-native": "^5",

您不需要安装

@babel/preset react

或

@babel/preset flow

---

希望这有帮助。

对于Babel 7及以上版本，请根据创建名为

bable.config.js

而不是

.babelrc

的文件，然后导出如下预设：

const presets = [
    "flow"
]

module.exports = {presets}

---

打开

.babelrc

文件，然后编辑代码的预设部分，如下所示：

  "presets": ["module:metro-react-native-babel-preset"],

---

我通过在我的项目中安装

“babel-preset-react-native-stage-0”

解决了这个问题，并更改了

。babelrc

文件：

"presets": [
    "babel-preset-react-native-stage-0/decorator-support"
  ]

---

你能解决这个问题吗？我有同样的错误：（@Guille No我无法修复此错误，因此我返回到react原生版本0.55.4，该版本对我来说没有错误。谢谢这也解决了我的问题，谢谢你为我节省了时间！谢谢这也解决了我的问题。尝试遵循我得到的此文档==错误：无法从中找到模块“babel预设流”-你的意思是“@babel/flow”？没有解决我的问题：s我正在使用解毒药，但仍然会遇到相同的错误，并对此作出反应

0.55.4

在此之后，我遇到了另一个问题，该问题在那里得到了解决，然后它开始工作

"presets": [
    "babel-preset-react-native-stage-0/decorator-support"
  ]
