Javascript 指定了插件0，提供了无效的属性"；“违约”；（开玩笑）

嘿，我只是试着运行一个简单的测试，在运行了“纱线测试”之后，我一直遇到这个错误，这是在开玩笑

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")

我不知道你是否已经解决了这个问题，但我也遇到了同样的问题，我能够用RN 0.56使事情再次正常工作。我改变了这一点：

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

到

以下是关于这个问题的完整讨论：

如果上述情况破坏了react原生环境，另一种解决方案是安装巴别塔桥：

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

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

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