Question

我的同事最近将react-native-camera添加到了我的项目中。我合并了代码，当我运行npx react-native run-android时，我的构建失败了：

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:preDebugBuild'.
> Could not resolve all task dependencies for configuration ':app:debugRuntimeClasspath'.
   > Could not resolve project :react-native-camera.

我尝试删除我的节点模块，然后执行npm install，但仍然遇到相同的错误。任何帮助都会很棒。预先感谢。

Answer 1

有时auto-link的{{1}}功能失败。

尝试手动链接库。请按照下列步骤。...

react-native-cli
npm install --save react-native-camera@git+https://git@github.com/react-native-community/react-native-camera.git
react-native link react-native-camera

Answer 2

删除React-Native-Camera依赖项，然后重新安装。运行

cd android

./gradlew clean

然后再次运行应用

Answer 3

这里也有同样的问题：

"Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0." -REACT-NATIVE

在android/app/build.gradle中添加这一行

android {
  ...
  defaultConfig {
    ...
    missingDimensionStrategy 'react-native-camera', 'general' <-- insert this line
  }
}

在此之后，如果您收到此错误：“任务':app:mergeDexDebug'react-native 的执行失败”

参考此链接：

Answer 4

使用以下命令

child: FutureBuilder<File>(
  key: ValueKey(imageUrl), // or use UniqueKey()  
  ...

然后通过运行转到android文件夹

npm cache clean --force

然后运行

cd android

然后运行

 ./gradlew clean

最后运行你的项目

npx react-native link react-native-camera

我的npx react-native run-android构建失败
