Strange tidyverse installation

[levi]

Few days ago, in order to change my library path, I referred to a video and added a function to RStudio.
Here is the video:
How do I change the default library path for R packages [Set R environment at start up permanently] - YouTube
I added a function as the video recommended (2:11) to Rprofile.site.

.First <- function(){
	.libPath("C:/Program Files/R/R-4.1.0/library")
}

After add this function, I could install my packages in the administrator mode.
However, when I install tidyverse, it came out:

also installing the dependency ‘rvest’


  There is a binary version available but the
  source version is later:
      binary source needs_compilation
rvest  1.0.0  1.0.1             FALSE

I installed rvest again, and it came out:

  source version is later:
      binary source needs_compilation

The mesage Error: cannot add binding of '.First' to the base environment Execution halted mentioned my added function.

Why does the error come out?

It is actually not necessary to use the .First() function, you can delete that and simply add this line to the Rprofile.site file.

.libPaths(c("C:/Program Files/R/R-4.1.0/library"))

Then restart your R session and try to install rvest again.

Thank you so much.
It works.
