reactjs - 无法运行 jetifier React Native

Question

我尝试运行react-native run-android，但收到此错误。

    it using "--no-jetifier" flag.

Answer 1

使用这个:

第1步:在gradlew.properties Visit for complete guideline中添加这两行

android.useAndroidX=true
android.enableJetifier=true

第 2 步:使用这些命令

首先删除node_modules文件夹并使用重新安装

npm install 

或

yarn

然后

npm install --save-dev jetifier 
npx jetify  
npx react-native run-android 

调用

npx jetify

每次(您的依赖项更新或每次安装node_modules时，您都必须再次jetify)
