tidyverse installation

Please do not post screenshots here, post formatted code instead.

In your screenshot you are showing a lot of error messages, the first step to start solving them would be to update R itself to the latest version (you are using a very old R version) and then update your packages with checkBuilt =TRUE option.

update.packages(checkBuilt=TRUE, ask=FALSE)

Then try to install tidyverse again and if you get an error message again, post it here.
