javascript expo 已过期 卸载并再次运行以升级

expo is out of date uninstall and run again to upgrade

提问by Andrew

when running my app on ios simulator, I am getting the following error This version of the Expo app is out of date. Uninstall the app and run again to upgrade.

在 ios 模拟器上运行我的应用程序时，出现以下错误 This version of the Expo app is out of date. Uninstall the app and run again to upgrade.

Here is how I tried to upgrade expo-cli yet not successful

这是我尝试升级 expo-cli 但未成功的方法

1. npm update -g

2. yarn add global expo-cli

3. npm uninstall expo-cli
4. npm cache clean --force
5. yarn add global expo-cli

1. npm update -g

2. yarn add global expo-cli

3. npm uninstall expo-cli
4. npm cache clean --force
5. yarn add global expo-cli

Here is app.json

这是 app.json

"expo": {
    "name": "firebase-reacte-native",
    "slug": "firebase-reacte-native",
    "privacy": "public",
    "sdkVersion": "32.0.0",
    "platforms": [
    ....

Here is package.json

这是 package.json

"dependencies": {
    "expo": "^32.0.0",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz"
  }

All I want to do is run ios-simulator without the error message on ios simulator as there was a problem loading the requested app. The experience you requested requires a newer version of the Expo Client app.

我想要做的就是运行 ios-simulator 而没有 ios 模拟器上的错误消息 there was a problem loading the requested app. The experience you requested requires a newer version of the Expo Client app.

The issue is to do with the app that is on the iOS simulator / device is out of date and is not compatible with the current version of Expo that you running.

问题与 iOS 模拟器/设备上的应用程序过时有关，并且与您运行的当前版本的 Expo 不兼容。

Delete the Expo app from the the iOS simulator and it should work, or install the latest update if you are on a device

从 iOS 模拟器中删除 Expo 应用程序，它应该可以工作，或者如果您在设备上安装最新的更新

One way to do it is with the simulator open is to Erase All Content and Settings. Then re-run npm start and the Expo App will be installed again on this device simulator.

一种方法是在模拟器打开的情况下将Erase All Content and Settings. 然后重新运行 npm start ，Expo App 将再次安装在此设备模拟器上。
