My mac system is macOS Catalina 10.15.1, and my R version is 3.6.1. When I try to install the rJava package on Rstudio using install.packages("rJava", type="source), it comes with error:
make: *** [jri_glue.o] Error 1
ERROR: compilation failed for package ‘rJava’
* removing ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rJava’
* restoring previous ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rJava’
Warning in install.packages :
installation of package ‘rJava’ had non-zero exit status
I have tried sudo R CMD javareconf and then reinstall the rJava package but it does not work. When I use sudo R CMD javareconf on terminal, it shows that

This problem happened before and I use this solution trouble installing and loading rJava on mac El Capitan. But when my mac is updated to Catalina 10.15.1, the solution does not work. I am not familiar with java. How to install rJava successfully in such situation?
