目前尚未启用对实验性语法“flow”的支持 (7:8)：

Question

我一直在使用 Mono 存储库与 React 应用程序共享 React Native 组件。当我尝试使用 React 中的 React Native 组件时，它一直显示一个我无法解决的错误。

我尝试按照说明进行操作，例如将 @babel/preset-flow 添加到预设中。但是，还是没有用。请帮帮我。

请看看我遇到的错误：

Add @babel/preset-flow (https://github.com/babel/babel/tree/main/packages/babel-preset-flow) to the 'presets' section of your Babel config to enable transformation.
If you want to leave it as-is, add @babel/plugin-syntax-flow (https://github.com/babel/babel/tree/main/packages/babel-plugin-syntax-flow) to the 'plugins' section to enable parsing.

您需要安装@babel/preset-typescript作为开发依赖项并添加您的 babel 配置。

npm install --save-dev @babel/preset-typescript

在你的 babel 配置 ( .babelrc) 文件中应该将其添加到你的预设中：

"presets": ["@babel/preset-typescript"]
