React Native 在 try {} 中抛出错误

Question

我将RNUI 安装到一个新的世博会项目中。简单地导入模块后，它会抛出这个错误：

Error: Problem validating fields in app.json. See https://docs.expo.io/workflow/configuration/
 • should NOT have additional property 'nodeModulesPath'.
Failed building JavaScript bundle.
Unable to resolve module react-native-haptic-feedback from /Users/xx/Documents/yy/zz/node_modules/react-native-ui-lib/src/optionalDependencies/HapticFeedbackPackage.js: react-native-haptic-feedback could not be found within the project.

If you are sure the module exists, try these steps:
 1. Clear watchman watches: watchman watch-del-all
 2. Delete node_modules and run yarn install
 3. Reset Metro's cache: yarn start --reset-cache
 4. Remove the cache: rm -rf /tmp/metro-*

  3 | try {
> 4 |   HapticFeedbackPackage = require('react-native-haptic-feedback').default;
    |                                    ^
  5 | } catch (error) {}
  6 |
  7 | export default HapticFeedbackPackage;

在我看来，它在 try {} 语句中引发错误似乎非常不合逻辑。相同的模块在旧的 Expo 项目（旧版本）中运行良好。

你需要安装react-native-haptic-feedback这个包，然后对它不起作用执行下面给出的步骤。

删除项目目录中的 node_modules 文件夹，关闭 Metro 捆绑器以及为该项目运行的所有内容。现在运行 npm install 它应该可以工作了。
