Question

这是我的第一个反应本机应用程序。我能够在iOS模拟器上成功运行此程序，但是使用Android emulator时，我遇到了问题。

我运行了以下命令yarn android。它打开了我的android emulator，但是构建失败，并出现异常。该应用由博览会管理。早期的仿真器无法打开已修复的路径。

这是详细的错误：

info JS server already running.

我发现了问题。它与JDK版本有关。

我已经安装了JDK的最新版本14。它在Gradle的5.x版本中无法正常工作。

因此，我安装了JDK 8，该版本可与Gradle的5.x版本一起使用。而且有效！没想到这就是问题所在...
