如何在react原生应用程序中启用ES2020

Question

我试图在我的react原生应用程序中添加ES2020功能，我安装了"babel-preset-es2020": "^1.0.2"并添加了.babelrc文件，如下所示：

{
"presets": ["es2020"]
}

但似乎什么都不起作用，这个错误正在出现：

error: Error: Unable to resolve module `./animations/TimingAnimation` from `node_modulesreact-native-reanimatedsrcAnimated.js`:
None of these files exist:

请告诉我一种在那里启用ES2020 的方法

您的错误似乎与react本机重新激活包有关，而不是ES版本。确保react native reanimated已安装在您的软件包.json中，否则：

npm i react-native-reanimated
