Question

我正在尝试运行react-native run-android但我不断得到这个错误。我在模拟器上运行。我使用FAILURE: Build failed with an exception. * What went wrong: A problem occurred configuring root project 'AwesomeProject'. > Could not resolve all dependencies for configuration ':classpath'. > Could not resolve com.android.tools.build:gradle:2.2.3. Required by: :AwesomeProject:unspecified > Could not resolve com.android.tools.build:gradle:2.2.3. > Could not get resource 'https://jcenter.bintray.com/com/android/tool /build/gradle/2.2.3/gradle-2.2.3.pom'. > Could not GET 'https://jcenter.bintray.com/com/android/tools/buil /gradle/2.2.3/gradle-2.2.3.pom'. Received status code 407 from server: Proxy Authentication Required启动了该应用。

PS：我在代理上运行。

当我试图运行时

react-native run-android

我明白了：

Error:Could not GET 
'https://jcenter.bintray.com/com/android/tools/build/gradle/2.2.3/gradle-
2.2.3.pom'. Received status code 407 from server: Proxy Authentication 
 Required
<a href="toggle.offline.mode">Enable Gradle 'offline mode' and sync 
project</a>

当我试图运行时

直接在Android Studio中

我明白了：

private void writeLogFile(string textInLog)
{
    //Creating a streamwriter to write to the file with the path of logFileName.
    using (var sw = new StreamWriter(logFileName))
    {
        sw.WriteLine(textInLog);
    }
}

我已经安装了node_modules，我不知道还有什么可以尝试的，我一直在谷歌搜索过去4个小时并且什么都没有。

Answer 1

在sdk manager中设置代理详细信息

AndroidStudio-＆gt; tools-＆gt; Android-＆gt; SDKManager-＆gt;系统设置 - ＆gt; Http代理

Answer 2

您的问题与npm和节点无关。你有一些gradle问题。检查你是否可以从浏览器访问URL？

Answer 3

它清楚地说<a href="toggle.offline.mode">Enable Gradle 'offline mode' and sync project</a>。您是否尝试过启用离线模式？如果没有，试试这个：

转到文件 - ＆gt;设置。

然后打开'构建，执行，部署'，然后打开'构建工具' - ＆gt; '摇篮'。

然后取消选中右侧的“离线工作”。

单击“确定”按钮。

然后重建项目。

对于Mac，请转到AndroidStudio - ＆gt;偏好，休息是一样的。

尝试在gradle.properties中添加这些：

systemProp.http.proxyHost=proxyURL
systemProp.http.proxyPort=proxyPort
systemProp.http.proxyUser=USER
systemProp.http.proxyPassword=PASSWORD
systemProp.https.proxyHost=proxyUrl 
systemProp.https.proxyPort=proxyPort
systemProp.https.proxyUser=USER
systemProp.https.proxyPassword=PASSWORD

无法使用react-native为Android构建
