     Required by:
         project :app
      > Cannot choose between the following variants of project :react-native-camera:

          - mlkitDebugRuntimeElements
        All of them match the consumer attributes:
          - Variant 'generalDebugRuntimeElements' capability baidupush:react-native-camera:unspecified:
              - Unmatched attributes:
                  - Found com.android.build.api.attributes.VariantAttr 'generalDebug' but wasn't required.
                  - Found react-native-camera 'general' but wasn't required.
              - Compatible attributes:
                  - Required com.android.build.api.attributes.BuildTypeAttr 'debug' and found compatible value 'debug'.
                  - Required com.android.build.gradle.internal.dependency.AndroidTypeAttr 'Aar' and found compatible value 'Aar'.
                  - Required org.gradle.usage 'java-runtime' and found compatible value 'java-runtime'.

              - Unmatched attributes:
                  - Found com.android.build.api.attributes.VariantAttr 'mlkitDebug' but wasn't required.
                  - Found react-native-camera 'mlkit' but wasn't required.
              - Compatible attributes:
                  - Required com.android.build.api.attributes.BuildTypeAttr 'debug' and found compatible value 'debug'.

二、解决方案

在android/app/build.gradle文件defaultConfig配置中添加missingDimensionStrategy 'react-native-camera', 'general'，然后再编译即可

完成代码如下
defaultConfig {
   applicationId "com.todayfood"
   minSdkVersion rootProject.ext.minSdkVersion
   targetSdkVersion rootProject.ext.targetSdkVersion
   versionCode 1
   versionName "1.0"
   missingDimensionStrategy 'react-native-camera', 'general'
}
