我在将旧的react-native项目升级到新的react-native版本（0.51.0）时非常艰难，当我尝试构建其抛出错误时，我当前的设置：
的build.gradle：
// Top-level build file where you can add configuration options common to all sub-projects/modules.
apply plugin: 'de.undercouch.download'
buildscript {
repositories {
jcenter()
google()
mavenCentral()
mavenLocal()
maven {
url 'https://maven.google.com'
}
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'de.undercouch:gradle-download-task:3.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
buildDir = "C:/tmp/${rootProject.name}/${project.name}" // temp for windows
repositories {
mavenCentral()
mavenLocal()
jcenter()
jcenter()
maven { url "$rootDir/../node_modules/react-native/android" }
maven { url "https://jitpack.io" }
maven { url 'https://maven.google.com' }
google()

/**
* The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets
* and bundleReleaseJsAndAssets).
* These basically call `react-native bundle` with the correct arguments during the Android build
* cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
* bundle directly from the development server. Below you can see all the possible configurations
* and their defaults. If you decide to add a configuration block, make sure to add it before the
* `apply from: "../../node_modules/react-native/react.gradle"` line.

* // the name of the generated asset file containing your JS bundle
* bundleAssetName: "index.android.bundle",

* // whether to bundle JS and assets in another build variant (if configured).
* // See http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Build-Variants

* // bundleInFreeDebug: true,
* // bundleInPaidRelease: true,
* // bundleInBeta: true,
*

* // for example: to disable dev mode in the staging build type (if configured)
* devDisabledInStaging: true,
* // The configuration property can be in the following formats
* // 'devDisabledIn${productFlavor}${buildType}'
* // 'devDisabledIn${buildType}'

* // that we don't look at files in android/ or ios/ to determine whether the tasks are up to

我使用Android Studio 3和Windows，遵循有关升级反应原生项目的官方文档并使用react-native升级，之后我使用了Building React Native from source
答案 0 :(得分：0)
我通过在 android / app / build.gradle 上添加以下内容来解决这个问题：
android {...}
configurations.all {
exclude group: 'com.facebook.react', module: 'react-native'
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '26.0.2'
}
}
}
}
请注意details.useVersion上的版本应与implementation 'com.android.support:appcompat-v7:26.0.2'
