在真实设备崩溃时反应原生构建（emul 工作）

Question

有人可以就我在这里做错了什么提出建议吗？

当通过XCode (9.2) 模拟器启动应用程序时，应用程序工作正常，在真实设备上构建它时 (iOS 11.2.6) 会进一步引发错误： 尝试了此处描述的步骤：https://github.com/facebook/react-native/issues/4831

Answer 1

您是否创建了 bundle.js 文件？ 试试这个：

react-native bundle --entry-file='index.js' --bundle-output='./ios/AppName/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'

你能提供更多关于你的 .babelrc 文件的信息吗？

Answer 2

我在安装 babel helper 插件时得到了这个修复。

Package.json:
"devDependencies": {
"babel-cli": "6.26.0",
"babel-plugin-external-helpers": "^6.22.0",
....
}

babelrc:
{
"presets": ["react-native", "flow"],
"plugins": [
"external-helpers",
...
]
}

安装此插件的参考： https://www.npmjs.com/package/babel-plugin-external-helpers
