android studio 3.2 无法解析 ':app@debug/compileClasspath' : Could not resolve com. android.support :appcompat-v7:27. 1.1 的依赖关系

Question

我正在使用 android studio 3.2，在使用这个之前我安装了 android studio 2.2。当我打开一个新项目时，我会收到下面提到的这些错误。我想再次提及，我没有对布局或 main.activity 进行任何更改。我已经检查了旧版本的解决方案，但问题仍然存在。这是我之前尝试过的:

将应用插件:'com.android.application'更改为应用插件:'com.android.library' - 取消选中离线模式。 - 添加存储库:

mavenCentral()
        maven {
            url "https://maven.google.com"
    }

- 将 appcompat 更改为旧版本(v7:26+ 或 v7:25) 以下是错误日志:

我真的纠结了2天浏览解决方案，我真的很迷茫。提前感谢您的时间、关注和帮助。

Answer 1

试试这个方法

1) Android Studio 3.1.4

2)

COMPILE_SDK_VERSION=26
BUILD_TOOLS_VERSION=27.0.3
TARGET_SDK_VERSION=26

3)

build.gradle{project}

buildscript {
    repositories {
        jcenter()
        google()
        mavenCentral()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'

    }
}

allprojects {
    repositories {
        jcenter()
        google()
        mavenCentral()
    }

}

4) 支持库版本应该相同，您可以使用 26.1.0 进行上述配置，例如 com.android.support:appcompat-v7:26.1.0

5) 最后一步是

gradle-wrapper.properties

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
