【中文标题】错误:无法确定当前字符,它不是 android react-native 中的字符串、数字、数组或对象【英文标题】:Error: Unable to determine the current character, it is not a string, number, array, or object in react-native for android 【发布时间】:2020-03-16 01:34:44 【问题描述】: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 运行良好。

* What went wrong:
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.

如错误消息所示,我尝试运行npm uninstall -g react-native react-native-cli
,但没有成功。

【问题讨论】:
您使用的是什么操作系统?我发现我的问题是由 android 构建文件夹中的文件权限引起的 - 不知道发生了什么,但在我的 Windows 10 机器上,我必须确保我以提升的权限启动了所有应用程序(Android Studio、VS Code、Windows 命令)(运行作为管理员)。 我使用的是 MacOS 我使用 CLI 重新创建了项目并开始工作:-( @TahirKhalid 意思是你使用 react-native init 开始了一个全新的项目?能详细说明一下吗,谢谢 是的,我重新创建了项目,但这次我确保权限正确。我会使用 MacOS 控制台并 chmod 文件夹和文件以确保正确的读/写访问 【参考方案1】: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)
请务必在任何地方删除它。我在 build.gradle (app) 和 settings.gradle 中有这一行。
之后,再次运行npx react-native run-android控制台会显示真正的错误,修复错误并放回你删除的行。
在我的情况下,发生错误是因为我一直在使用较旧的 Node 版本,第二次发生了我需要再次同步我的项目
解决方案 2
删除它发现错误为“当前读取的字符是'E',int值为69”的文件
删除
app\build\intermediates\signing_config\debug\out\signing-config.json
也为其他人工作过。
解决方案 3
将@react-native-community/cli 更新到最新版本。
编码不错!
【讨论】:
直接在 MacOS 上从 nodejs 安装也对我有用,谢谢!进行 brew 安装,即使使用卸载和重新链接步骤也不起作用。建议将您的答案直接突出显示 nodejs 下载,然后使用以下解决方法。 原来我还是有这个问题。解决方法帮助我在android/app/src/main/AndroidManifest.xml
文件中看到了一个微小的语法错误。现在修复了这个问题,我可以重新打开其他线路。
感谢分享。我会更新答案以使其更清楚!
@Kelton.Temby,您可以编辑我的答案,以便您提到的其他用户更清楚。【参考方案2】:
我认为这个问题只在较新的版本(0.61)我有同样的问题,我只是使用旧版本(0.60.0)
npx react-native init AwesomeProject --version 0.60.0
【讨论】:
【参考方案3】:刚刚删除了 android 中的 build 文件夹并转到 android 文件夹,然后在 powershell 中输入./gradlew
clean 然后cd..
=> npx react-native run-android
【讨论】:
【参考方案4】:请确保 AndroidManifest.xml 数据使用正确的引号“”而不是“”。这通常发生在我们配置 firebase 并复制粘贴依赖项时。
【讨论】:
该死的人,我从我的 xml 中的某个网站复制粘贴它,我没有注意到非常感谢【参考方案5】:删除 android/app/release
对我有用。
【讨论】:
【参考方案6】:检查您的androidmanifest.xml
,该文件中会有一些问题..
就我而言,我编辑了我的androidmanifest.xml
,这就是为什么我收到该错误并通过将androidmanifest.xml
的编辑代码放在前面来解决该错误。
谢谢你:)
【讨论】:
【参考方案7】:删除node_modules
文件夹并再次运行npm install
对我有用
【讨论】:
【参考方案8】:在项目文件夹中按照以下步骤操作
cd android
./gradlew clean
cd ..
npm install
react-native run-android
【讨论】:
【参考方案9】:首先,您应该尝试关闭模拟器。在 Windows 中,当我尝试使用运行此错误的模拟器进行构建时。
【讨论】:
【参考方案10】:也许您的 npm(节点)服务器正在启动。 如果服务器开始关闭它。
【讨论】:
【参考方案11】:删除node_modules
文件夹并再次运行npm install
,它对我有用!
【讨论】:
【参考方案12】:对我来说,在 Cygwin 下,问题原来是应用程序顶层目录中名为 app
的符号链接(android
上方,node_modules
旁边),它指向它所在的完整路径居住(例如/cygdrive/c/files/app
)。它是在我开始构建的时候创建的。删除后问题就解决了。
