我正在使用以下软件版本：
(Mac OS Big Sur)
react-native-cli: 2.0.1
react-native: 0.64.1
yarn: 1.22.10
android-sdk: 29.0.3
javac: 16.0.2
我正在尝试从 https://github.com/square/react-native-square-reader-sdk/tree/master/reader-sdk-react-native-quickstart运行演示。gradle.properties所有文件都与此演示中的文件几乎相同（唯一的区别是使用我的凭据插入的推荐新行）。
我npx @react-native-community/cli doctor成功传递了命令（我已经ANDROID_HOME设置，我有正确的 JDK 和 Android SDK 等......）。我目前正在使用外部 Android 设备测试我的软件。
当我react-native run-android在主目录中运行时，这是我的回溯：

我gradew.bat在我的/android目录中，这令人困惑，因为它似乎是大多数“gradlew”问题的来源。
React Native Error: spawn gradlew.bat ENOENT的解决方案不起作用，因为tns install产生以下输出：
No project found at or above '/Users/myuser/Documents/GitHub/react-native-square-reader-sdk' and neither was a --path specified.
