Node + R-script + postgres

I have used the library R-script to connect Node js to R and runs, but when I call a R script which uses library RPostgreSQL I get this error:

xxxx/node_modules/r-script/index.js:42 if (child.stderr) throw child.stderr; ^ Loading required package: DBI Note: the specification for S3 class “AsIs” in package ‘DBI’ seems equivalent to one from package ‘jsonlite’: not turning on duplicate class definitions for this class.

I understand the error, a name conflict, but how can I solve it?
