【问题描述】：
我正在尝试安装GetDFPData包，但是出现了这个错误：
checking Java support in R... present:
interpreter : '/usr/bin/java'
archiver : '/usr/bin/jar'
compiler : '/usr/bin/javac'
header prep.: '/usr/bin/javah'
cpp flags : ''
java libs : ''
configure: error: One or more Java configuration variables are not set.
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.
ERROR: configuration failed for package ‘rJava’
* removing ‘/home/rtheodoro/R/x86_64-pc-linux-gnu-library/3.6/rJava’
我检查了很多答案，但还没有解决。
我正在使用 Linux Mint 19.2 肉桂。
当我运行sudo R CMD javareconf 时，我有：

在/usr/lib/jvm，我有四个文件夹：ibm-java80-jre-x86_64、java-1.8.0-openjdk-amd64、java-8-openjdk-amd64、java-ibm-x86_64-80。我不知道为什么。
有人可以帮我吗？
【问题讨论】：
-
不清楚您是否安装了 JDK（这是 R 依赖项）。打开控制台并尝试
javac -version并让我们知道响应。注意：我不是要java -version——我想查看编译器版本。 -
是的，我有：javac 1.8.0_222
