RStudio Required Package Versions Could Not Be Found

Question

I updated my Mac to OS10 and attempting to run RStudio Knit, and get the error:

"evaluate 0.7.2 is required but 0.7 is available".  

I tried this and did not fixed the issue:

remove.packages("evaluate")
install.packages("evaluate")

Any help would be appreciated.

Answer 1

Try setting up the below option and by rerunning the code.

getOption("repos")
options(repos = c(CRAN = "https://cran.rstudio.org"))

Answer 2

It also happened to me. I downloaded evaluate zip file from here https://cran.rstudio.com/web/packages/evaluate/index.html and then manually installed it in R Studio (Tools-InstallPackages-zip file). Good luck !
