Rscript “there is no package”

问题

I have a script that loads data, processes it, and saves the processed data out. I run it manually without a problem, but it does not work with Rscript. It uses the data.table package, and Rscript cannot find it. I have tried the solution here but get the following error message:

Error in eval(expr, envir, enclos) :   could not find function ".getNamespace" 
In addition: Warning message: package ‘data.table’ was built under R version 3.1.1 Error : unable to load R code in package ‘chron’ 
Error: package/namespace load failed for ‘data.table’
Execution halted

The script looks like:

#!/usr/local/bin/Rscript
args = commandArgs(trailingOnly = TRUE)  # Take arguments from command line
library.path <- '/home/zack/R/x86_64-redhat-linux-gnu-library/3.1'
library('data.table', lib.loc = library.path)

That code is after failing with library(data.table). But I can load data.table fine, and so the rest of the script works, if I do this manually. The command I submit to bash is:

nohup /usr/local/bin/Rscript --vanilla <path to script> <args> &

which Rscript:

/usr/local/bin/Rscript

/usr/local/bin/R loads data.table fine when it is called in an interactive session.
