Question

我尝试首先使用react-native run-android运行一个react-native应用程序。我希望它能够正常工作，就像我打电话给react-native run-ios时一样。堆栈中有很多用户遇到同样的错误，“无法通知项目评估监听器”。

正如OP对提交的bug的评论中所提到的，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，8之后的版本不起作用）并告诉Gradle使用它，而不是系统上的默认Java版本。

在我的情况下（运行Ubuntu 18.04），这需要安装openjdk-8-jdk（我已经有JDK 11和JRE 8但不是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

行

org.gradle.java.home=/usr/lib/jvm/java-8-openjdk-amd64

在build.gradle中包含以下内容：

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的同样错误。

事实上，我正在运行Java 9，运行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)

要彻底解决，我做到了：

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）重新安装Java 8-download here

3）在我的bash文件（〜/ .bash_profile）中添加了JAVA_HOME行：

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，现在一切正常。感谢您的帮助@ user149408！
