在根项目'android‘React Native中找不到'installDebug’

Question

我正试图在android模拟器上运行我的项目。当我运行react-native run-android时，我得到了以下信息：

FAILURE: Build failed with an exception.

* What went wrong: Task 'installDebug' not found in root project 'android'.

* Try: Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

如果我运行./gradlew tasks，我会得到：

Build Setup tasks
-----------------
init - Initializes a new Gradle build. [incubating]
wrapper - Generates Gradle wrapper files. [incubating]

Help tasks
----------
buildEnvironment - Displays all buildscript dependencies declared in root project 'android'.
components - Displays the components produced by root project 'android'. [incubating]
dependencies - Displays all dependencies declared in root project 'android'.
dependencyInsight - Displays the insight into a specific dependency in root project 'android'.
help - Displays a help message.
model - Displays the configuration model of root project 'android'. [incubating]
projects - Displays the sub-projects of root project 'android'.
properties - Displays the properties of root project 'android'.

你知道为什么我的项目中没有installDebug任务吗？我怎么才能把它拿回来？

Answer 1

react-native run-android --变体productFlavorName

例如，react-native run-android --变种华为run

Answer 2

用于调试测试

react-native run-android --variant devKernelDebug

原因是因为在android/build.gradle文件中有这样的文件

  productFlavors {
    devKernel {
      dimension 'remoteKernel'
    }
    prodKernel {
      dimension 'remoteKernel'
    }
  }

Answer 3

我在running react-native start之后的fresh react-native项目(react-native init projectname)中遇到了同样的问题，然后在VS代码中使用react-native run-android。它给出了这个错误

Task 'installDebug' not found in project ':app'.

在RN "0.62.1“中

解决方案：-我打开Android Studio，然后清理并重建。

我不确定在清理和重建后它是否会工作。

我也这样做了，并给出了根项目中的sdk路径

export ANDROID_HOME=/home/mycomputer/Android/Sdk/
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

然后它就起作用了。

我的npm版本6.7.0我的节点版本v11.10.1 react-native-cli: 2.0.1 react-native: 0.62.1
