我需要在我的ubuntu操作系统上安装rhadoop。当我安装rmr2包时，我遇到了这个错误

library(rmr2)
Loading required package: Rcpp
Loading required package: RJSONIO
Loading required package: digest
Loading required package: functional
Loading required package: stringr
Loading required package: plyr
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared object '/home/mahi/R/x86_64-pc-linux-gnu-library/3.0/rmr2/libs/rmr2.so':
  libRcpp.so: cannot open shared object file: No such file or directory
Error: package or namespace load failed for ‘rmr2’

有人知道怎么了吗？
