title: tidyverse package will not load
body: <p>I am running the latest version of Rstudio (1.1.453) on Mac. Since installing the latest version of R-Studio, I can no longer get tidyverse package to load. Any suggestions on how I can fix this?</p>
  
  <p>I get the following error message. </p>
  
  <pre><code>&gt; library("tidyverse", lib.loc="/Library/Frameworks/R.framework/Versions/3.5/Resources/library")
  Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
   there is no package called ‘dplyr’
