指定了插件0，提供了“ default”的無效屬性（Jest React Native）

Question

嘿，我只是想運行一個簡單的測試，而在運行使用jest的“ yarn test”后，我一直遇到此錯誤。

Plugin 0 specified in "/Users/Documents/Dev/appname/node_modules/babel-preset-react-native/index.js" provided an invalid property of "default" (While processing preset: "/Users/Documents/Dev/appname/node_modules/babel-preset-react-native/index.js")

  at Plugin.init (node_modules/babel-core/lib/transformation/plugin.js:131:13)
  at Function.normalisePlugin (node_modules/babel-core/lib/transformation/file/options/option-manager.js:152:12)
  at node_modules/babel-core/lib/transformation/file/options/option-manager.js:184:30
      at Array.map (<anonymous>)
  at Function.normalisePlugins (node_modules/babel-core/lib/transformation/file/options/option-manager.js:158:20)
  at OptionManager.mergeOptions (node_modules/babel-core/lib/transformation/file/options/option-manager.js:234:36)
  at node_modules/babel-core/lib/transformation/file/options/option-manager.js:265:14

      at Array.map (<anonymous>)
  at OptionManager.resolvePresets (node_modules/babel-core/lib/transformation/file/options/option-manager.js:275:20)

這是我的package.json，我缺少什么，我確定它是配置問題而不是測試問題。

不知道您是否已經解決了問題，但我遇到了同樣的問題，並且我能夠使用RN 0.56重新使事情正常。 我改變了這個：

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

至

"babel-preset-react-native": "4.0.0",

這是圍繞該問題的完整討論： https : //github.com/storybooks/storybook/issues/3897

如果以上方法破壞了您的react-native env，則另一個解決方案是安裝babel-bridge：

npm install babel-core@7.0.0-bridge.0 --save-dev
