RStudio Required Package Versions Could Not Be Found

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.

install.packages('evaluate')
Warning in install.packages :
  unable to access index for repository HTTP://cran.rstudio.com/bin/windows/contrib/3.4:
  cannot open URL 'HTTP://cran.rstudio.com/bin/windows/contrib/3.4/PACKAGES'

When you compile the update or remove sentences, if the output like this, you could make some settings, since maybe the problem is your internet. Follow the steps:

  1. Open Rstudio.
  2. Click tools.
  3. Choose global options->packages.
  4. Modify CRAN to the country you living. like, China or Japan. Cause your browser maybe work only you do this.

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

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

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 !
