升级到react-native：0.60.4后，我无法运行我的应用，并且出现了react-native版本不匹配错误。

package.json

Answer 1

1- 关闭所有终端 / bash屏幕

2-打开新的bash并转到项目文件夹

cd ~/Documents/projects/myProject

3- 运行您的项目

react-native run-ios //react-native run-android

4- npm在您的路径上开始

myProject$ npm start

最好！

Answer 2

对此没有确切的解决方案，因为所有系统以及安装和变体版本都是无止境的。

因此，为了最好地解决此问题而又不拔头发，是

使用react-native更新您的npx react-native upgrade
以防万一也像这样npm install -g react-native-cli
然后使用npx react-native init AwesomeProject
然后在您的package.json中查看新项目中react和react-native的版本，并将它们与您的工作项目进行比较

例如这是我的工作项目

        "expo-barcode-scanner": "~8.2.1",
        "expo-linear-gradient": "~8.2.1",
        "expo-status-bar": "^1.0.2",
        "react": "~16.11.0",
        "react-dom": "~16.11.0",
        "react-native": "^0.61.4",

这是我的新项目Package.json

    "expo-splash-screen": "^0.5.0",
    "expo-status-bar": "^1.0.0",
    "expo-updates": "~0.2.10",
    "react": "~16.11.0",
    "react-dom": "~16.11.0",
    "react-native": "~0.62.2",

然后，最后我使用了新项目中的react和react-native版本，它们都运行良好

这是我工作项目的最终代码

        "expo-barcode-scanner": "~8.2.1",
        "expo-linear-gradient": "~8.2.1",
        "expo-status-bar": "^1.0.2",
        "react": "~16.11.0",
        "react-dom": "~16.11.0",
        "react-native": "~0.62.2",

Answer 3

有可能要执行的请求消息正确。执行消息。

watchman watch-del-all && react-native start --reset-cache

Answer 4

最后我用自己的方式解决了。

创建另一个空项目
将您的资源+ packages.json复制到新项目中
不要在新项目中安装npm

问题解决了。

反应本机版本不匹配0.60.4
