using xlsx with R jupyter notebook

I am trying to install and use the xlsx lackage in R in a Jupyter notebook on a Mac.

install.packages("xlsx")

seems to run OK but

library("xlsx")

results in:

Error: package or namespace load failed for 'xlsx':
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rJava/libs/rJava.so':

Traceback:

 . }, error = function(e) {
 .     P <- if (!is.null(cc <- conditionCall(e))) 
 .         paste(" in", deparse(cc)[1L])
 .     else ""
 .     msg <- gettextf("package or namespace load failed for %s%s:\n %s", 
 .         sQuote(package), P, conditionMessage(e))
 .     if (logical.return) 
 .         message(paste("Error:", msg), domain = NA)
 .     else stop(msg, call. = FALSE, domain = NA)
 . })
3. tryCatchList(expr, classes, parentenv, handlers)
4. tryCatchOne(expr, names, parentenv, handlers[[1L]])
5. value[[3L]](cond)
6. stop(msg, call. = FALSE, domain = NA)

I tried sudo R CMD javareconf which resulted in:

What am I missing?

library(readxl)

df<- read_xlsx(path,sheet= sheet number) #use this if you want to import xlsx

df<- read_xls(path,sheet= sheet number) #use this if you want to import xls
