我的 npx react-native run-android 构建失败

Question

我的同事最近在我的项目中添加了react-native-camera 。 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.
     Required by:

                  - Found react-native-camera 'mlkit' but wasn't required.

我试图删除我的节点模块，然后进行npm install ，但我仍然遇到相同的错误。 任何帮助都会很棒。 提前致谢。

Answer 1

删除 React-Native-Camera 依赖项并再次安装和。 跑

cd android

./gradlew clean

并再次运行应用程序

Answer 2

有时react-native-cli auto-link功能会失败。

尝试手动链接库。 按着这些次序....

1. npm install --save react-native-camera@git+https://git@github.com/react-native-community/react-native-camera.git
2. react-native link react-native-camera
3. npx react-native run-android

Answer 3

同样的问题在这里得到了照顾：

“此版本中使用了已弃用的 Gradle 功能，使其与 Gradle 7.0 不兼容。” -反应本机

在android/app/build.gradle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”

参考这个链接：

Answer 4

使用以下命令

npm cache clean --force

然后通过运行转到android文件夹

cd android 

然后运行

 ./gradlew clean

然后运行

npx react-native link react-native-camera

最后运行你的项目

npx react-native run-android

Answer 5

在./android/app/build.gradle 中插入这一行：

defaultConfig {... missingDimensionStrategy 'react-native-camera', 'general' }

Answer 6

在 ./android/app/build.gradle 中插入这一行

defaultConfig { ... targetSdkVersion rootProject.ext.targetSdkVersion missingDimensionStrategy 'react-native-camera', 'general' versionCode 1 versionName "1.0" }
