libjvm.so: cannot open shared object file: No such file or directory

Question

Trying to install the rJava package on R, on my 14.10 ubuntu, using this code

if (!require(rJava)) install.packages('rJava') 

got few errors related to java including jni problems, after reinstalling the jdk, and tried to run the same code again, got that error

Error : .onLoad failed in loadNamespace() for 'rJava', details:   call: dyn.load(file, DLLpath = DLLpath, ...)   error: unable to load shared object '/usr/local/lib/R/site-library/rJava/libs/rJava.so':   libjvm.so: cannot open shared object file: No such file or directory Error: loading failed Execution halted ERROR: loading failed * removing ‘/usr/local/lib/R/site-library/rJava’ Warning in install.packages :   installation of package ‘rJava’ had non-zero exit status  The downloaded source packages are in     ‘/tmp/RtmpfFjrp0/downloaded_packages’ Warning message: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE,  :   there is no package called ‘rJava’ 

looked for solutions, to find just about everyone suggesting (for x64) to execute those commands

export LD_LIBRARY_PATH=/usr/lib/jvm/java-8-oracle/lib/amd64:/usr/lib/jvm/java-8-oracle/jre/lib/amd64/server sudo R CMD javareconf  

but that didn't work, is there anything else I can do? I will provide any needed details

Answer 1

To solve this,

1. Run

   sudo R CMD javareconf

2. Add the following to to /etc/environment. This will then be set every time your machine restarts.

   LD_LIBRARY_PATH=/usr/lib/jvm/default-java/jre/lib/amd64/server/

   (change to your path)

3. Run the following:

   source /etc/environment

4. rstudio server restart

Answer 2

I was getting the same error when I was trying to load rJava in RStudio. The following solution worked for me

1) sudo rstudio-server stop 2) export LD_LIBRARY_PATH=/usr/lib/jvm/jre/lib/amd64:/usr/lib/jvm/jre/lib/amd64/default 3) sudo rstudio-server start 

After performing the above steps, I was able to run the following successfuly in RStudio

> library("DBI") > library("rJava") > library("RJDBC")
