Could not install package ‘readr’!

Good day to everyone!

I need to launch swirl course Getting and Cleaning Data:

Tidying Data with tidyr

when I launch it says:

This lesson requires the 'readr' package. Would you like me to install it for you now?

| Trying to install package 'readr' now... Warning in install.packages : installation of package 'readr' had non-zero exit status

| Could not install package 'readr'! |
| 0% Error in seq.default(0, 1, length = nrow(e$les)) : argument 'length.out' must be of length 1

| Leaving swirl now. Type swirl() to resume.
