无法在Ubuntu 13.04中的R 3.0中安装rJava

Question

我不能叫rJava包R 3.0.我收到以下消息

Error: package ‘rJava’ was built before R 3.0.0: please re-install it

我试图重新安装rJava包时遇到错误.我提供了输出R CMD javareconf

我正在使用Ubuntu 13.04.我也尝试过apt-get install r-cran-rjava没有帮助解决这个问题.关于jni.h,这里有一些解决方案.但是,不知道我怎么能在这里使用解决方案.

Answer 1

我遇到了完全相同的问题.我的解决方案是安装openjdk-7-*via

sudo apt-get install openjdk-7-*

跟着那个

sudo R CMD javareconf

然后我就可以在R via中安装rJava了install.packages("rJava").

虽然也许不是最优雅的解决方案,但似乎已经解决了让rJava工作的问题.

Answer 2

对于那些得到错误的人:

error: unable to load shared object '/some/dir/rJava/libs/rJava.so': libjvm.so: 
cannot open shared object file: No such file or directory

我解决了在系统中定位库并将它们链接到的错误/usr/lib:

$sudo updatedb
$locate libjvm.so
/usr/lib/debug/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so
/usr/lib/debug/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/zero/libjvm.so
