找不到滿足版本約束的“com.android.support:appcompat-v7”版本

Question

當我嘗試在 Android Studio 中編譯我的應用程序時，我遇到了“react-native-geolocation-service”問題。

  Cannot find a version of 'com.android.support:appcompat-v7' that satisfies the version constraints: 
   Dependency path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7:26.1.0'
   Constraint path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7' strictly '26.1.0' because of the following reason: debugRuntimeClasspath uses version 26.1.0
   Dependency path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7:26.1.0'
   Constraint path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7' strictly '26.1.0' because of the following reason: debugRuntimeClasspath uses version 26.1.0
   Dependency path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7:26.1.0'
   Constraint path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7' strictly '26.1.0' because of the following reason: debugRuntimeClasspath uses version 26.1.0
   Dependency path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7:26.1.0'
   Constraint path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7' strictly '26.1.0' because of the following reason: debugRuntimeClasspath uses version 26.1.0
   Dependency path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.android.support:appcompat-v7:26.1.0'
   Dependency path 'UnalAR:react-native-geolocation-service:unspecified' --> 'com.facebook.react:react-native:0.57.8' --> 'com.android.support:appcompat-v7:27.1.1'

我的 android/app/build.gradle

dependencies {
compile project(':react-native-simple-compass')
compile project(':react-native-heading')
compile project(':react-native-geolocation-service')
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.facebook.react:react-native:+'
implementation project(':arcore_client') // remove this if AR not required
implementation project(':gvr_common')
implementation project(path: ':viro_renderer')
implementation project(path: ':react_viro')
implementation 'com.google.android.exoplayer:exoplayer:2.7.1'
implementation 'com.google.protobuf.nano:protobuf-javanano:3.0.0-alpha-7'
implementation 'com.amazonaws:aws-android-sdk-core:2.7.7'
implementation 'com.amazonaws:aws-android-sdk-ddb:2.7.7'
implementation 'com.amazonaws:aws-android-sdk-ddb-mapper:2.7.7'
implementation 'com.amazonaws:aws-android-sdk-cognito:2.7.7'
implementation 'com.amazonaws:aws-android-sdk-cognitoidentityprovider:2.7.7' }

我在 這里遵循了 react-native-geolocation-service 文檔，但是只有當我包含這個庫時才會出現這個錯誤。

我認為錯誤在

實現 'com.android.support:appcompat-v7:28.0.0'

但我害怕改變它。

謝謝各位幫我。

你是對的。 查看該項目的代碼，它似乎檢查您是否覆蓋了項目中的版本（當這些問題出現時，許多依賴項開始這樣做）。 因此，進入您的項目 build.gradle（而不是 app/build.gradle），您可以覆蓋該庫正在使用的版本：

buildscript {
    ext {
        ...
        supportLibVersion = "28.0.0"
        ...
    }
}
