错误：无法确定当前字符，它不是Android的react-native中的字符串，数字，数组或对象

每当我在保持模拟器运行的同时运行react-native run-android时，都会出现此错误。react-native run-ios程序完全正常。

A problem occurred evaluating script.
> Failed to parse React Native CLI configuration. Expected running 'npx --quiet --no-install react-native config' command from '/Users/yashatreya/Desktop/Realyze/Realyze' directory to output valid JSON, but it didn't. This may be caused by npx resolving to a legacy global react-native binary. Please make sure to uninstall any global 'react-native' binaries: 'npm uninstall -g react-native react-native-cli' and try again

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

如错误消息中所示，我尝试运行，npm uninstall -g react-native react-native-cli但没有运行。

您使用什么操作系统？我发现我的问题是由android build文件夹中的文件权限引起的-不知道发生了什么事，但是在Windows 10计算机上，我必须确保以提升的权限（运行）启动了所有应用程序（Android Studio，VS Code，Windows Command）以管理员身份）。
— 塔希尔·哈立德
我正在使用MacOS
— yashatreya，
我使用CLI重新创建了该项目，该项目开始工作：-(
— Tahir Khalid
@TahirKhalid意味着您使用react-native init开始了一个全新的项目？能否请您详细
— 说说
是的，我重新创建了项目，但是这次我确保权限正确。我将使用MacOS控制台并chmod文件夹和文件以确保正确的读/写访问权限

解决方案1（为我工作）

我的解决方案是删除以下行

apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)

确保将其删除。我在build.gradle（app）和settings.gradle中有这行。

之后，再次运行npx react-native run-android，控制台将显示实际错误，修复错误并放回已删除的行。

就我而言，发生错误是因为我一直在使用旧版本的Node，而第二次发生是因为我需要再次同步项目

解决方案2

删除发现错误的文件为“当前字符读取为'E'，int值为69”

删除中 

app\build\intermediates\signing_config\debug\out\signing-config.json

也为别人工作。

解决方案3

将@ react-native-community / cli更新到最新版本。

好的编码！

在MacOS上直接从nodejs安装也对我有用，谢谢！即使进行了卸载和重新链接步骤，也无法进行Brew安装。建议提出答案，以突出显示直接下载的nodejs，然后采用以下解决方法。

原来我还是有问题。解决方法帮助我在android/app/src/main/AndroidManifest.xml文件中看到一个微小的语法错误。修复此问题后，我能够重新打开其他线路。

刚刚删除了android内部的build文件夹，然后转到android文件夹，然后在powershell中键入./gradlewclean然后 cd..=>npx react-native run-android

请确保AndroidManifest.xml数据使用正确的引号“”而不是“”。这通常在我们配置Firebase并复制粘贴依赖项时发生。
