Question

当我尝试执行以下代码时，我的本机应用程序出现错误

react-native run-android --variant=release

Starting a Gradle Daemon (subsequent builds will be faster)

> Configure project :react-native-firebase
react-native-firebase: using React Native prebuilt binary from /Users/sanglee/Documents/react-native-firebase-starter/node_modules/react-native/android

FAILURE: Build failed with an exception.

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

我从react-native-firebase下载了react-native应用，甚至无法在android上进行测试。

发生这种情况是因为不存在密钥库。请遵循https://facebook.github.io/react-native/docs/0.60/signed-apk-android

中提到的步骤

您可以使用keytool生成私钥。（说明因操作系统而异）
编辑文件~/.gradle/gradle.properties或android/gradle.properties，然后添加以下内容（用正确的密钥库密码，别名和密钥密码替换*****）

 MYAPP_UPLOAD_STORE_FILE=my-upload-key.keystore 
 MYAPP_UPLOAD_KEY_ALIAS=my-key-alias
 MYAPP_UPLOAD_STORE_PASSWORD=*****
 MYAPP_UPLOAD_KEY_PASSWORD=*****

在您的项目文件夹中编辑文件android/app/build.gradle，并添加签名配置，

...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_UPLOAD_STORE_FILE')) {
                storeFile file(MYAPP_UPLOAD_STORE_FILE)
                storePassword MYAPP_UPLOAD_STORE_PASSWORD
                keyAlias MYAPP_UPLOAD_KEY_ALIAS
                keyPassword MYAPP_UPLOAD_KEY_PASSWORD
            }
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}
...

确保您在Windows中使用PowerShell，而不是Git Bash

在项目'：app'中找不到任务'installDebug'
