'C:/Users/???/

Does your user name contain non-ASCII characters or empty spaces? R has problems with non-ASCII characters in the package library folder.

You can change the default library folder by setting your R_LIBS_SITE environmental variable on a .Reviron or .Rprofile file

# In a .Renviron file you can set it by adding this line
R_LIBS_SITE="C:\\Program Files\\R\\R-4.0.5\\library"

For a more detailed explanation, you can read this blog post

but I still can't find where is Renviron file to add the line given.

It doesn't exist by default, you have to create a file with that name, for more details please click on the link I gave you before and read the blog post.

Hi Andresrcs,

I still not sure how to create that file after reading the blog. I downloaded those packages manually and can create rmarkdown but it shows error after knit. Do u have a simply way to solve it? Pls help provide detailed steps and screenshots. Thank you.
