title: Trouble installing rlang in R
body: <p>I have just updated my RStudio to 4.1.2 and since then I lost all my packages. I successfully re-installed most of them except for rlang.</p>
  <p>I keep receiving this message every time I try to install it. This problem is keeping me away from using other packages because they require rlang. I would really appreicate it if someone can help me out.</p>
  <pre><code>&gt; install.packages(&quot;rlang&quot;)
  
    There is a binary version available but the source version is later:
        binary source needs_compilation
  rlang  1.0.2  1.0.3              TRUE
  
  Do you want to install from sources the package which needs compilation? (Yes/no/cancel) Yes
  installing the source package ‘rlang’
