Shiny Error: Unable to establish connection with R session

I'm new with R so all help would be greatly appreciated.

Often those shiny logs and tracebacks are useful to others trying to help out. Second, strive to minimize the effort required to replicate your issue.

Thanks for your reply. Yes, I have included install.packages() command. It's weird, because I fallowing a tutorial and I stacked with the first chapter. Please see my code for ui.R below:

install.packages("shiny")
library(shiny)

shinyUI(fluidPage(

titlePanel(title = "Hello Shiny"),
sidebarLayout(
sidebarPanel("This is sidebar panel"),
mainPanel("Main output is diplay here")
)
)
)

code for server.R below
library(shiny)

shinyServer(
function(input, output){

}
)
