RN - android - can't find variable:Symbol

原文： https://blog.csdn.net/xiaoxnn/article/details/84938456

错误： react native0.57.7版本在集成mobx最新版本包 can't find variable:Symbol

原因：mobx的版本用的最新版本..用到了 Symbol部分es6的api特性.

解决的办法：

https://github.com/react-community/jsc-android-buildscripts#how-to-use-it-with-my-react-native-app

步骤：

1.Add jsc-android to the "dependencies" section in your package.json:

dependencies { "jsc-android": "236355.1.1",}

  npm install

2.在android/build.gradle文件添加以下内容：

allprojects {

    repositories {

        mavenLocal()

        google()

        jcenter()

        maven {

            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm

            url "$rootDir/../node_modules/react-native/android"

        }

        maven { url "https://jitpack.io" }

        maven { url "https://maven.google.com" }

        + maven {

        +      // Local Maven repo containing AARs with JSC library built for Android

        +      url "$rootDir/../node_modules/jsc-android/dist"

        + }

    }

}

3. app's build.gradle 文件下添加以下内容

+configurations.all {

+    resolutionStrategy {

+        force 'org.webkit:android-jsc:r236355'

+    }

+}

dependencies {

    compile fileTree(dir: "libs", include: ["*.jar"])

这样接可以了
