Question

我试图从'expo'导入Expo。但是我收到了以下错误消息：

error: bundling failed: Error: Unable to resolve module `expo` from `C:\Users\reactnative\navigate\App.js`: Module `expo` does not exist in the Haste module map.

This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
  1. Clear watchman watches: `watchman watch-del-all`.
  2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
  3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
  4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

package.json中的依赖项

{ “ name”：“ navigate”， “ version”：“ 0.0.1”， “私人”：是的， “脚本”：{ “ start”：“节点node_modules / react-native / local-cli / cli.js开始”， “ test”：“开玩笑” }， “依赖关系”：{ “反应”：“ 16.6.3”， “ react-native”：“ 0.58.5”， “反应导航”：“ ^ 3.3.2” }， “ devDependencies”：{ “ babel-core”：“ 7.0.0-bridge.0”， “ babel-jest”：“ 24.1.0”， “ jest”：“ 24.1.0”， “ metro-react-native-babel-preset”：“ 0.52.0”， “ react-test-renderer”：“ 16.6.3” }， “笑话”：{ “ preset”：“ react-native” } }

无法从“ expo”导入Expo。在本地反应中
