我使用以下命令创建新的react-native项目:

react-native init myProject

但是当我想使用以下命令在模拟器或真实设备上运行它时:

react-native run-android

我收到此错误,应用无法构建:

FAILURE: Build failed with an exception.

* What went wrong:
fresco/1.10.0/fresco-1.10.0.pom'.
         > Could not GET 'https://jcenter.bintray.com/com/facebook/fresco/fresco

            > Connect to 127.0.0.1:9595 [/127.0.0.1] failed: Connection refused:

在build.gradle中,我添加了google(),但没有解决问题。 这是我的build.gradle:

buildscript {
    ext {
        buildToolsVersion = "27.0.3"
        minSdkVersion = 16
        compileSdkVersion = 27
        targetSdkVersion = 26
        supportLibVersion = "27.1.1"
    }
    repositories {
        maven { url "https://maven.google.com" }
        jcenter()
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven { url "https://maven.google.com" }
        google()
        jcenter()
        maven { url "https://jitpack.io" }
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}
task wrapper(type: Wrapper) {
    gradleVersion = '4.4'
    distributionUrl = distributionUrl.replace("bin", "all")
}

请任何人帮助。

最后我找到了答案。 我在Android Studio中打开项目的android文件夹,并尝试与代理和下载的相关依赖项同步项目。然后,我运行此命令并成功构建项目。

react-native run-android

我遇到了这个问题,我可以通过使用代理来解决
