无法运行"ANY"反应本机示例项目

Question

我想在Ubuntu 14.04上运行UIExplorer项目.我已经安装了SDK和NDK.我可以运行通常的本地反应项目(我创建的那个),但不是官方回购的例子.

export ANDROID_NDK=/home/bozzmob/android-ndk-r10e/

我收到以下错误 -

任务'执行失败':ReactAndroid:buildReactNdkLib'.

进程'命令'/ home/bozzmob/android-ndk-r10e/ndk-build''以非零退出值2结束

日志看起来像 -

root@purvotara:~/ReactJS/native/react-native# ./gradlew :Examples:UIExplorer:android:app:installDebug
.

请让我知道我做错了什么？

似乎您在编译react-native android 的本机（c++）源时遇到问题。为了启动新项目，您不需要这样做（不需要 NDK 设置），因此您可以尝试创建示例项目react-native init（请参阅此说明）。之后，您只需将示例应用程序 JS 文件复制到新创建的项目即可。

如果您仍然想从源代码构建框架代码，我需要更多详细信息来帮助您。我建议为 ndk-build 启用详细模式，然后您可以返回此处查看输出。为了启用详细模式，您需要修改此文件：ReactAndroid/build.gradle并添加'V=1'到 args，以便我链接到的代码片段如下所示：

    commandLine getNdkBuildFullPath(),
        'NDK_PROJECT_PATH=null',
        'V=1',
        "NDK_APPLICATION_MK=$projectDir/src/main/jni/Application.mk",
        'NDK_OUT=' + temporaryDir,
