react-native - 应用程序 :compileDebugJavaWithJavac FAILED

Question

我成功地设置了 react native 在 Windows 上的 android 中创建新应用程序。但是当我尝试在模拟器中运行应用程序时，我陷入了下面提到的错误。谁能帮我解决这个问题？
提前致谢...

>react-native run-android

operable program or batch file.

Starting the packager in a new window is not supported on Windows yet.
Please start it manually using 'react-native start'.
We believe the best Windows support will come from a community of people
using React Native on Windows on a daily basis.
Would you be up for sending a pull request?

我遇到了同样的问题。您需要设置JAVA_HOME环境变量。要做到这一点:

按 Ctrl+Alt+T 打开终端。

输入以下命令:$ subl /etc/environment .

根据您安装 Java 的位置，您需要提供完整路径。在这个例子中，我安装了 JDK 1.7在 /usr/lib/jvm/jdk1.7.0_79目录。滚动到文件末尾并输入以下内容:
JAVA_HOME="/usr/lib/jvm/jdk1.7.0_79"
export JAVA_HOME


保存您的文件并退出 sublime。

最后，使用以下命令重新加载系统路径:$ . /etc/environment .

这应该可以解决您的问题。
