我正在尝试在 Ubuntu 16 服务器上安装“rJava”R 包。
我尝试了一些方法，例如重新安装 JDK、运行脚本来设置主路径以及运行 R CMD javareconf（也带有 -e 命令）。
Here is the error I am getting at this point:

Make sure R is configured with full Java support (including JDK). Run
R CMD javareconf
as root to add Java support to R.
If you don't have root privileges, run
R CMD javareconf -e
to set all Java-related variables and then install rJava.

有什么建议吗？
答案1
Java 9、10、11 因查找附加库的问题而臭名昭著。
我选择返回 Java 8，而不是使用 -headless 版本。这对我有以下帮助：
sudo apt remove openjdk-10-jre-headless
sudo apt remove openjdk-11-jre-headless
sudo apt remove openjdk-8-jre-headless
sudo apt install openjdk-8-jre
