我正在按照react-native官方步骤安装和运行应用程序( https://facebook.github.io/react-native/docs/getting-started.html )。一切都很好(安装react-native和其他库，运行ios版本)，但是react-native run-android失败并出现以下错误。我想到的是 OSX El Capitan 和 OpenSSL 的问题，但几个月前我尝试修复它并解决了所有问题。但我没有找到任何关于这个特定错误的信息。
我尝试通过brew install gradle安装gradle，但react-native仍然尝试再次安装。也许有一种方法可以告诉react-native不要再次安装它？
感谢您的帮助

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html
最佳答案
在我搞乱 OpenSSL 后，我在 El Capitan 上遇到了同样的问题。这意味着您的 Java 证书已搞砸。
最后，我通过重新安装JDK解决了这个问题。
您可以通过首先删除以下位置的当前 JDK 来完成此操作:
/Library/Java/JavaVirtualMachines/jdkmajor.minor.macro[_update].jdk
然后运行:
sudo rm -rf jdk1.X.X_XX.jdk
再次安装您的 JDK 版本，一切都应该可以正常工作!
旁白
此问题的其他症状包括无法运行任何与 SSL 相关的“获取”功能。例如，运行 Android 包管理器会出现错误，指出无法从 https 服务器获取 xml 文件。
关于java - 在react-native run-android期间安装Gradle时出现SSL错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36378468/
