Error installing text2vec package

I am trying to install text2vec package using the command:
install.packages("text2vec", lib = "/usr/share/R/library")

I am getting the error:

from HashCorpus.h:17,

  • removing ‘/usr/share/R/library/text2vec’

The downloaded source packages are in
‘/tmp/RtmpEpLvyr/downloaded_packages’
Warning message:
In install.packages("text2vec", lib = "/usr/share/R/library") :
installation of package ‘text2vec’ had non-zero exit status

I tried uninstalling Rcpp, reinstalling Rcpp - no luck.
Please help.
Thanks
