我正在开发expo SDK版本：36，并且在所有平台上（ios/android/web）
当按照documentation中的说明第一次安装react-navigation并运行jest --watch时，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.

最后一个提供了一个解决方案，但它说要打开Xcode，而我在Linux Debian 10。我没有Xcode。我可以使用MacBook和做的步骤，但我想知道：

  • 在Linux上工作时，我应该关心吗？
  • 我应该关心当工作的MacBook（如果它发生）？
  • 我应该在测试时关注应用的运行状况吗？在哪些情况下？
jestjs

若要禁用此警告，请将以下任一项添加到测试文件中。

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

或

jest.mock('NativeAnimatedHelp');

在package.json文件中

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

单位：mock.js

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

您可以放心地忽略此警告。useNativeDriver仅在设备上运行代码时才重要。

上面没有什么不适合我，但最终我找到了解决方案here：
1.创建jest-setup.js文件（在我的例子中在src/tests目录中）：

源代码/测试/jest-setup.js：

import 'react-native-gesture-handler/jestSetup';

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

jest.mock('react-native-reanimated', () => {
  const Reanimated = require('react-native-reanimated/mock');

  // The mock for `call` immediately calls the callback which is incorrect
  // So we override it with a no-op
  Reanimated.default.call = () => {};

  return Reanimated;
});

1.安装必要的软件包（在我的例子中只安装react-native-reanimated，但也许你的代码会问你其他问题）：

npm install --save-dev react-native-reanimated

1.向package.json中的jest配置添加一行：

"jest": {
    "setupFiles": [
      "<rootDir>/src/tests/jest-setup.js"
    ]
  },

如果您的jest-setup.js文件位于其他目录-相应地更改位置。
经过这些简单的步骤，恼人的警告已经消失了。感谢斯宾塞卡利和他的文章通过链接以上。
