Babel错误:插件/预设文件不允许导出对象，仅可导出功能 [英] Babel Error: Plugin/Preset files are not allowed to export objects, only functions

问题描述

我正在尝试在博览会安装上运行故事书.所以到目前为止，我只在应用程序中看到了博览会和故事书.

I'm trying to run storybook on an expo installation. So I only got expo and storybook in the app so far.

我无法启动网络故事书.

I'm not able to start the storybook for web.

我的package.json看起来像这样:

My package.json looks like this:

"dependencies": {
  "expo": "^32.0.0",
  "react": "16.5.0",
  "react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz"
},
"devDependencies": {
  "@babel/core": "^7.2.2",
  "@babel/preset-env": "^7.2.3",
  "@babel/preset-react": "^7.0.0",
  "@babel/runtime": "^7.2.0",
  "@storybook/addon-actions": "^4.1.6",
  "@storybook/addon-knobs": "^4.1.6",
  "@storybook/addon-links": "^4.1.6",
  "@storybook/addon-ondevice-knobs": "^4.1.6",
  "@storybook/addon-ondevice-notes": "^4.1.6",
  "@storybook/addons": "^4.1.6",
  "@storybook/react": "^4.1.6",
  "@storybook/react-native": "^4.1.6",
  "babel-loader": "^7",
  "babel-preset-expo": "^5.0.0",
  "prop-types": "^15.6.2",
  "react-dom": "16.5.0"
},

我的babel.config.js看起来像这样；

My babel.config.js looks like this;

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ['babel-preset-expo'],
  };
};

我也尝试过:

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ["@babel/env", "@babel/react"],
  };
};

尝试运行故事书时出现此错误:

I get this error when trying to run the storybook:

即使我的addons.js为空，它也会失败.

It fails even though my addons.js is empty.

推荐答案

那对您没有帮助. 您仍然需要addon.js文件.

That won't help you. You still need your addon.js file.

我认为您需要等待它.
