Question

我使用命令react-native init appName创建新的react native应用程序。应用程序创建成功后，使用命令react-native run-android将其安装在我的设备中，安装成功，并且运行正常...没问题

但是当我安装react导航和手势处理程序后，我得到的错误是命令失败：运行命令react-native run-android后gradlew.bat installDebug 我不知道这是怎么回事...我的旧React Native项目运行得很好。

我记得昨天我在一个旧项目中运行了gradlew clean命令。.这对我的新项目有影响吗？

如果有人帮忙我会很感激

这是完全错误

Answer 1

哦，是的，我认为这是RN 0.58链接命令的错误

使用=>'D：\ React Native Apps \ Practice \ newapp \ android \ settings.gradle'中的文本编辑器打开settings.gradle

将所有'\'替换为'/'，在我的情况下，我不得不将'.. \ node_modules \ react-native-gesture-handler \ android'替换为'../node_modules/react-native-gesture-handler / android'

然后react-native运行Android
