react-native - 使用 Hermes 的 React native 应用程序崩溃并显示 "SIGSEGV: Segmentation violation (invalid memory reference) "

Question

在我们的崩溃跟踪应用程序 bugsnag 中，我看到越来越多的崩溃与“SIGSEGV:分段违规(无效内存引用)”。它们似乎只发生在 Android 上，堆栈跟踪充满了 libhermes.so。

这个堆栈跟踪没有告诉我任何信息，而且我还没有发现任何存在相同问题的问题。有谁知道在哪里寻找根本原因？ hermes 变成 SIGSEGV 是 javascript 错误吗？爱马仕的bug？我们使用的其中一个库发生崩溃？

其中一次崩溃的堆栈跟踪。

Answer 1

Hermes 是您“可以”使用的 ReactNative 的新 JavaScript 引擎。

如果你不想使用它，你必须像这里描述的那样做一些配置步骤:https://reactnative.dev/docs/hermes

如果您的应用程序中启用了 Hermes，您可以检查您的 android/app/build.gradle 文件。 如果是，请注意，hermes 不支持“android-bundles”，而只支持 apk-Packages。

也许(我只是猜测)您之前还激活了 hermes，但现在从 APK 切换到 Android-Bundles。

顺便说一句: 您是否使用 logcat 获取堆栈跟踪？如果没有，请试一试。大多数情况下，它会在设备屏幕的 App-Stacktraces 中显示您不会看到的错误消息。
