Mint中JAVALinux问题

Question

我正在尝试安装GetDFPData包，但出现以下错误：

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：

*** JAVA_HOME is not a valid path, ignoring

$ javac -version

在usr/lib/jvm中，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。

有人能帮我吗？

Answer 1

我解决了。我在R CMD javareconf尝试了“请不要嘲笑我”的答案，但没有找到jni. h

所以我做了：

（1） 更新所有存储库（2）确保安装了JRE和JDK 8（3）然后，正如许多用户已经说过的那样，用指向JDK 8的显式路径将R指向java
