我创建一个新应用程序并插入一个旧代码，当我构建该应用程序出现此错误：
脚本'C：\ Users \ nameuser \ Desktop \ nameapp \ node_modules @ react-native-community \ cli-platform-android \ native_modules.gradle'行：191
出了什么问题：
评估设置'nameapp'时出现问题。
无法确定当前字符，它不是字符串，数字，数组或对象
当前读取的字符为'i'，int值为105无法确定当前字符，它不是字符串，数字，数组，或对象行号1索引号0信息运行“ react-native --help”以查看所有可用命令的列表。
使用native-native info命令，我有当前情况：

感谢您的帮助。
构建过程执行：
npx --quiet react-native config要么npx.cmd --quiet react-native config
该命令，如果您在项目的根目录中执行，将产生JSON输出（如果一切配置正确）。
然后，在您引用的gradle脚本中解析JSON输出。如果没有正确配置，npx --quiet react-native config将不产生任何结果或无效的输出。因此，JSON解析（第191行）将失败。
调用'npx --quiet react-native config'的整个机制在最新版本的react-native中使用，因此它将自动将您package.json中拥有的所有react native软件包“绑定”到您的Android Java应用。（它基本上会在应用编译时注入所有这些包名称）。

[遗憾的是，没有一个'解决方法'可以帮助您解决此问题。您可能有不匹配项（或配置有误）
我目前推荐的最好的方法是升级到最新版本您可以负担得起的React版本，然后使用
https://github.com/react-native-community/rn-diff-purge
要找出在工作版本和停止工作的RN版本之间进行上述配置文件所需的所有更改。
