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
