无法使用.R文件上的Rscript连接到RJDBC

Question

我试图运行一个R脚本，我尝试使用RJDBC连接到Amazon Redshift。 这是我连接Redshift的代码。

drv<-JDBC("com.amazon.redshift.jdbc42.Driver","/home/soumyadeep/Downloads/RedshiftJDBC42-1.1.17.1017.jar") 
con<-dbConnect(drv,"jdbc:redshift://170.31.0.129:5439/dev","query","5vIU")
Traffic_Over <- gsub('[\r\n\t]','',paste(readLines("Queries_Marketing/Traffic.sql"), collapse = " ")) 
Traffic_Overall<-dbGetQuery(con,Traffic_Over)

当我在Linux终端上运行脚本时，我会遇到以下错误。

Loading required package: methods
