Problem during installation of tidyverse in R - r

Question

I am trying to install the tidyverse package, during installation package "callr" returned an error, so i tried to diagnose the issue by seprately installing it,
While doing so, its dependency "processx" returned an installation error. I tried searching online for the error but without no avail.
Here is the installation log.

Answer 1

I am sorry, and thank you for your valuable time.
The problem exists because i think the way my system is installed, no process can acess any files in /proc.
And as to why, took me some tinkering to figure that by myself (not very good with systems).
here is a link to the relevant issue
Anyways, there does not seem to be any problem with processx, so i can close this thread, i suppose, and once again thank you for your valuable time.
