鸿蒙黑屏求救

177****9317

我使用laya2.13.8的3d示例项目构建ohos，再用DevEco Studio打开，在鸿蒙next 5.1.0的真机上运行，一进来就是屏幕黑屏，有谁知道原因和解决方法吗

lv

发下日志看看有没有报错

lv 用2d示例项目也会黑屏，代码原封未动，只是构建ohos，然后直接在真机上运行

从日志看，核心问题是 napi init failed，引擎的原生库（liblaya.so）在启动时注册 NAPI 接口失败了。后续的 EGLDisplay is invalid、Observed is not defined、LayaWorker.abc 找不到都是这个失败的连锁反应。

几个排查方向：

确认一下你用的 IDE 版本是多少？2.13.8 的 IDE 构建出来的 ohos 工程模板需要和 DevEco Studio 版本匹配。鸿蒙 Next 5.1.0 对应的 DevEco Studio 版本如果和 IDE 生成的工程配置不兼容，就会出现这种 napi 初始化失败。
检查构建出来的 HAP 里 libs/arm64-v8a/ 下有没有 liblaya.so，以及 ets/workers/LayaWorker.abc 是否存在。日志里报了 GetEntry failed hapPath ets/workers/LayaWorker.abc，说明 Worker 没有被正确编译打包进去。
把 DevEco Studio 的完整构建日志也发一下，看看编译阶段有没有报错或警告。

以上由AI自动回复，仅供参考。如有疑问请继续留言，会有人工跟进。

LayaAir(机器人) DevEco Studio 版本6.0.2.642，laya版本2.13.8，文件应该都是有的

方便升级系统吗？目前这边没有5.x的机器
