React Native安卓项目构建失败：react-native-socketio编译报错求助

我开发的安卓项目基于React Native，用到了socket.io、gradle和react-native-sms-x，执行npm run android时构建失败，报错信息如下：

C:\Users\user\Desktop\SmsApp> npm run android

> SmsApp@0.0.1 android
> react-native run-android

info JS server already running.

info 💡 Tip: Make sure that you have set up your development environment correctly, by running react-native doctor. To read more about doctor command visit: https://github.com/react-native-community/cli/blob/main/packages/cli-doctor/README.md#doctor

解决方案 #

方法1：升级项目全局compileSdkVersion #

1. 打开项目根目录下的android/build.gradle文件
2. 找到ext代码块中的compileSdkVersion，将其修改为30或更高版本（推荐使用33，适配最新安卓版本）：

   buildscript {
       ext {
           compileSdkVersion = 33
           minSdkVersion = 21
           targetSdkVersion = 33
           // 其他配置项...
       }
       // 其余代码...
   }
   

3. 保存文件后，执行npm run android重新构建

方法2：单独指定react-native-socketio的compileSdkVersion #

若不想升级项目全局版本，可单独为该依赖设置兼容版本：

1. 打开android/build.gradle，在allprojects代码块上方添加：

   subprojects {
       afterEvaluate { project ->
           if (project.name == 'react-native-socketio') {
               android {
                   compileSdkVersion 30
                   targetSdkVersion 30
               }
           }
       }
   }
   

2. 保存后重新执行构建命令

方法3：更新react-native-socketio至最新版 #

旧版本依赖可能存在兼容性问题，执行以下命令更新：

npm install react-native-socketio@latest --save

更新完成后再次尝试构建
