Oracle JDK 9 is NOT installed.

为什么下载失败并且 Oracle JDK 9 未安装。我该如何修复？
答案1
我尝试从 Oracle 官方网站手动下载 Oracle Java 9：http://www.oracle.com/technetwork/java/javase/downloads/jdk9-downloads-3848520.html并且下载 jdk-9.0.4_linux-x64_bin.tar.gz 的链接有效。您的另一个选择是从默认的 Ubuntu 17.10 存储库安装 openjdk-9-jdk。
如果你在让 Java 9 与 React JavaScript 库正常工作时遇到问题，请不要放弃，因为你可以同时安装多个版本的 Java，并按照以下说明从终端设置 Java 版本如何设置默认 Java 版本？。
