Error on stan when running 8school example

i just installed rstan in R, but it can not work.

i just followed the procedure 'Example 1: Eight Schools' in getting start.

The error is as follow.

library("rstan")
Loading required package: StanHeaders
Loading required package: ggplot2
rstan (Version 2.19.3, GitRev: 2e1f913d3ca3)
For execution on a local, multicore CPU with excess RAM we recommend calling
options(mc.cores = parallel::detectCores()).
To avoid recompilation of unchanged Stan programs, we recommend calling
rstan_options(auto_write = TRUE)
For improved execution time, we recommend calling
Sys.setenv(LOCAL_CPPFLAGS = '-march=corei7 -mtune=corei7')
although this causes Stan to throw an error on a few processors.
options(mc.cores = parallel::detectCores())
rstan_options(auto_write = TRUE)
Sys.setenv(LOCAL_CPPFLAGS = '-march=corei7')
schools_dat <- list(J = 8,

R version 3.5.3
Rtools version 3.5.0.4
Rstan version 2.19.3

Start by reproducing the Eight Schools example with 8schools.stan using the reported R 3.5.3, Rtools 3.5.0.4, and rstan 2.19.3 versions. Inspect the failing R CMD SHLIB compilation command and its C++ output; done means the example compiles and the stan(file = '8schools.stan', data = schools_dat) call runs successfully.
