将React Native升级到0.60-RC2后，无法找到库"libjsc.so"。

Question

我已将React Native更新至0.60-RC2版本，并使用Android Studio重构迁移至AndroidX，同时使用这里提到的jetifier工具：https://github.com/react-native-community/discussions-and-proposals/issues/129。在完成以上步骤后，在运行react-native run-android命令或者发布APK时，会出现错误信息library "libjsc.so" not found。

以下是错误堆栈信息：

什么是 libjsc.so 文件，如何解决这个错误？

打开 gradle.properties => 添加 Android.useDeprecatedNdk=true - hong developer

已经在那里了。我仍然收到错误提示。 - khateeb

Answer 1

请在你的app/build.gradle文件顶部添加以下内容：

def useIntlJsc = false

//依赖项内部内容

 if (useIntlJsc) {
        implementation 'org.webkit:android-jsc-intl:+'
    } else {
        implementation 'org.webkit:android-jsc:+'
    }

我实际上删除了旧项目，从react-native init创建了一个新项目，并将我的代码复制到了新项目中，然后它就可以工作了。所以我无法测试这个修复。如果你100%确定这个可行，那么我会标记为已接受。 - khateeb

这样做可以解决libjsc.so的错误，但是现在我在一个全新的RN 0.60 RC2项目中出现了libgnustl_shared.so未找到的问题。 - Can Poyrazoğlu

这个解决方案无效。我收到了以下错误信息：/com.simplewebview E/SoLoader: 找不到要加载的DSO：libjscexecutor.so，原因是：dlopen失败：找不到库"libgnustl_shared.so" /com.simplewebview E/AndroidRuntime: 致命异常：create_react_context 进程：com.simplewebview，PID：26654 java.lang.UnsatisfiedLinkError：找不到要加载的DSO：libjscexecutor.so，原因是：dlopen失败：找不到库"libgnustl_shared.so" - Krishnan Sriram

可以分享一下可用的 build.gradle 和 package.json 文件吗？ - red-devil

遇到了与 libgnustl_shared.so 相同的问题。有人有解决方案并能够合理解释为什么它不在 React Native 文档中吗？ - Chris

Answer 2

我也遇到了这个问题。我需要在 build.gradle 文件中更新 jscFlavor 变量，从这个值：

def jscFlavor = 'org.webkit:android-jsc:+'

转化为：

def jscFlavor = 'org.webkit:android-jsc-intl:+'

干杯。

这个确实帮了我大忙。非常感谢你。我的应用程序中确实使用了i18n。 - Nguyễn Anh Tuấn

Answer 3

我遇到了这个bug的一个小变化，我的gradle配置中添加了第三个buildType，叫做“releaseStaging”。

在这种情况下，修复方法是在app/build.gradle文件中的dependencies中添加以下行：

releaseStagingImplementation files(hermesPath + "hermes-release.aar")

- anthonyhumphreys

救了我！我正在使用自定义的分段变量，而Hermes无法工作，谢谢！ - Nati Sholman Oskar

同样的问题。Hermes 必须在每个需要它的 buildType 中启用。这个更改对我解决了问题。 - lffloyd

Answer 4

我解决问题的方法是更改build.gradle并更新packagingOptions为：

  packagingOptions {
       pickFirst 'lib/x86/libc++_shared.so'
       pickFirst 'lib/x86/libjsc.so'
       pickFirst 'lib/x86_64/libjsc.so'
       pickFirst 'lib/arm64-v8a/libjsc.so'
       pickFirst 'lib/arm64-v8a/libc++_shared.so'
       pickFirst 'lib/x86_64/libc++_shared.so'
       pickFirst 'lib/armeabi-v7a/libc++_shared.so'
       pickFirst 'lib/armeabi-v7a/libjsc.so'
    }

- Tiago Gouvêa

我在我的build.gradle中没有看到任何这样的内容。这是React Native的新安装部分吗？https://react-native-community.github.io/upgrade-helper/?from=0.61.5&to=0.63.0 - Chris

@Chris 我不这么认为。但如果你安装了react-native-pdf，这是一个你被要求添加的东西：https://github.com/wonday/react-native-pdf/#android-installation - 可能是路径不正确/不包含给定架构的JSC，所以当你在那个特定的手机/架构上运行它时，它是一个有效的应用程序...只是不适用于那个手机，所以它会崩溃，因为缺少JSC（JavaScript引擎）。 - Seph Soliman

Answer 5

好的！在最近的React Native版本中，这个问题一直存在，并且在你集成应用程序中的Crashlytics或日志中可以看到。

只有在启用Hermes引擎时才会出现此问题。

以下是我解决这个问题的方法。在我的情况下，需要使用Hermes，所以我通过从npm安装jsc-android包来解决"libjsc.so" not found问题。这里是link。

请注意：根据你的React Native版本，请参考此软件包的文档进行正确的安装。

清理gradle并重新运行整个应用程序，这个问题就会消失。

- HarshitMadhav

Answer 6

在我的情况下，这个错误与react-native-screen有关，在android/app/build.gradle的依赖项中添加以下两行代码解决了我的问题。

implementation 'androidx.appcompat:appcompat:1.1.0-rc01'
implementation 'androidx.swiperefreshlayout:swiperefreshlayout:1.1.0-alpha02'
