我试图首先运行一个带有react-native run-android的 react-native 应用程序。我希望它能工作，就像我打电话给react-native run-ios时一样。有很多用户在堆栈上出现相同类型的错误，"未能通知项目评估侦听器"。

正如OP提交的错误评论中提到的，Gradle似乎在Java 9或更高版本中存在问题。
您需要安装 JDK 8(JRE 是不够的，高于 8 的版本将不起作用(并告诉 Gradle 使用它，而不是系统上的默认 Java 版本。
就我而言(运行 Ubuntu 18.04(，这需要安装openjdk-8-jdk(我已经有 JDK 11 和 JRE 8，但没有 JDK 8(。
您可以通过多种方式告诉 Gradle 使用 JDK 8(在所有示例中，将路径替换为 JDK 安装的实际路径;此处显示的路径对 Ubuntu 18.04 amd64 有效(：
-
使用选项运行 Gradle
-Dorg.gradle.java.home=/usr/lib/jvm/java-8-openjdk-amd64 -
确保
~/.gradle/gradle.properties包含该行org.gradle.java.home=/usr/lib/jvm/java-8-openjdk-amd64 -
在您的
build.gradle中包括以下行：compileJava.options.fork = true compileJava.options.forkOptions.executable = /usr/lib/jvm/java-8-openjdk-amd64
这帮助我摆脱了不同项目上的相同错误。
事实上，我运行的是Java 9，运行一个java --version给了我：
$: java --version
java 9
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)
为了完全解决它，我做了：
1(删除了Java 9：
sudo rm -rf "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin"
sudo rm -rf "/Library/PreferencePanes/JavaControlPanel.prefPane"
sudo rm -rf "~/Library/Application Support/Java"
2( 安装回 Java 8 - 在此处下载
3(在我的bash文件中添加了JAVA_HOME行(~/.bash_profile(：
nano ~/.bash_profile
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home
* 注意在路径上使用正确的jdk版本
而且，现在一切都很好。感谢您@user149408帮助！
我已经通过清理所有 Gradle 缓存、停止 Gradle 守护进程并使用以下命令成功创建了一个新版本来解决此问题。确保您当前的目录是安卓的。
rm -rf ~/.gradle/caches && ./gradlew --stop && ./gradlew cleanBuildCache && ./gradlew bundleRelease
