javascript - 如何解决 "Animated: ` useNativeDriver` 不受支持，因为缺少 native 动画模块。”在 react 导航中？

Question

我正在开发 expo SDK 版本:36，并且适用于所有平台(ios/android/web)

首次安装 react-navigation 时，如 documentation 中所述并在执行时运行 jest --watch ，出现以下警告:

    console.warn node_modules/react-native/Libraries/YellowBox/YellowBox.js:71
      Animated: `useNativeDriver` is not supported because the native animated module is missing. Falling back to JS-based animation. To resolve this, add `RCTAnimation` module to this app, or remove `useNativeDriver`. More info: https://github.com/facebook/react-native/issues/11094#issuecomment-263240420

它也会发生在浏览器控制台中:

bundle.js:18272 Animated: `useNativeDriver` is not supported because the native animated module is missing. Falling back to JS-based animation.

最后一个提供了解决方案，但它说要打开 Xcode，而我使用的是 Linux Debian 10。我没有 Xcode。我可以使用 Macbook 执行该步骤，但我想知道:

• 在 Linux 上工作时我应该关心吗？
• 在 Macbook 上工作时我应该关心(如果发生这种情况)吗？
• 测试时我应该关心应用程序的运行状况吗？什么情况下？

要禁用此警告，请将以下任一内容添加到您的测试文件中。

jest.mock('react-native/Libraries/Animated/NativeAnimatedHelper');

或

jest.mock('NativeAnimatedHelp');

在您的package.json 文件中

"jest": {
    "setupFiles": [
      "./mock.js"
    ],

在mock.js

中

jest.mock('react-native/Libraries/Animated/NativeAnimatedHelper');
jest.mock('NativeAnimatedHelp');
