新安装的Geogebra不打开(包括JDK问题)

Question

刚才在我的Ubuntu16.04上安装了geogebra (带有普通的旧sudo apt-get install geogebra)

当我试图打开它时，我得到：

GeoGebra 4.0.34.0 (Debian version 4.0.34.0+dfsg1-3) 22 June 2012 Java 9-internal
*** Message from [geogebra.main.Application.setUpLogging]

我想这与我的JDK有关，但我不知道该怎么做。我的java -version输出：

openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src)
OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode)

有人能帮我解决这个问题吗？

Answer 1

Java 9还没有正式发布，所以我非常怀疑任何主流的Java应用程序都在使用它。我不知道您是如何安装的，但我建议您安装JDK 8。

update-java-alternatives应该可以作为命令使用(取决于您的操作系统)，但是在您安装JDK 8之后，您可以运行它并选择它将Java8设置为您的系统的Java版本。

或者您可以自己编辑PATH和JAVA_HOME，但是当有更简单/更安全的方法时，我不会推荐它。
