Rjava Load Error in Rstudio/R After "Upgrading" to Osx Yosemite

rJava load error in RStudio/R after upgrading to OSX Yosemite

I had the same problem and went through the same steps as you. The final step to allow starting RStudio through Finder/Spotlight was to link libjvm.dylib to /usr/local/lib:

sudo ln -f -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

-f flag is added to force overwriting existing file/link

trouble installing and loading rJava on mac El Capitan

The problem was rJava wont install in RStudio (Version 1.0.136). The following worked for me (macOS Sierra version 10.12.6) (found here):

Step-1: Download and install javaforosx.dmg from here

Step-2: Next, run the command from inside RStudio:

install.packages("rJava", type = 'source')

Java error in MacOS Mojavew when loading a package

Based on @Konrad's answer I did the following to get rid of all versions except Java 8.

Check for existing versions

/usr/libexec/java_home -V

Navigate to that version of Java that needs to be uninstalled.

cd /Library/Java/JavaVirtualMachines

In the JavaVirtualMachines path, type in ls to see what versions of Java are existing there. It showed up as,

jdk-11.0.2.jdk      jdk-12.0.1.jdk      jdk1.8.0_211.jdk

removed all except 8.

sudo rm -rf jdk-11.0.2.jdk (and others)

library(xlsx) works now.

R, loading rJava error

It works!

After installing and reinstalling different java versions and reinstalling rJava with the R command install.packages("rJava") I got to the point where loading the library in the R console (shell window) didn't throw an error message anymore.

After that I was able to use the answer in this post to get it to work in RStudio by running this shell command:

sudo ln -f -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

Not too complicated after all! Thank you for everyones patience.
