android - 无法获取资源 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.2.1/gradle-3.2.1.pom'

Question

我最近开始使用 react native，但是根据伊朗人的制裁，gradle 不能构建我的第一个项目，所以我使用了 VPN 和 shecan service但我收到以下错误:

我阅读了 React native 说明并按照它们操作，设置了模拟器、react native cli 和 chocolaty 服务。在环境中，我应该在名为 PATH 的变量中定义我的 SDK 的平台工具文件夹。但是在变量中，我已经在用户名和系统变量中有了路径。在编辑中，我已经向它们添加了我的平台工具。但不幸的是，它还没有奏效。

图像中的 PowerShell 错误消息是:

PS C:\Others\RN_projects\React_native_shop\shop_project> react-native run-android

将此代理信息添加到您的 gradle.properties 文件中:

systemProp.https.proxyPort=9595
systemProp.http.proxyHost=127.0.0.1
systemProp.https.proxyHost=127.0.0.1
systemProp.http.proxyPort=9595

并在您的 vpn 中设置上述代理端口(例如 9595)，例如 psiphon。然后同步项目。
