Problem installing and downloading rJava on mac El Capitan

Question

You have a problem installing rJava, most of the troubleshooting steps done here do not work.

It returns an error

Loading required package: rJava
Error: package or namespace load failed for 'rJava':
 .onLoad failed in loadNamespace() for 'rJava', details:
 call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object     '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/    rJava.so':

I am in the latest version of R / Rstudio and Mac El Capitan

I also tried this method 1, which did not work

sudo R CMD javareconf

Then in the interpreter R:

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

method 2

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

error ln: /usr/local/lib/libjvm.dylib: File exists

method 3 install.packages ("rJava", type = "binary") error: tar: Failed to set the default locale

to resolve the default locale error

system("defaults write org.R-project.R force.LANG en_US.UTF-8")

when loading rJava, all the same error:

image not found

It looks like it is installed, but it does not load
