title: Failed to load library tidyr in R (version 4.1)
body: <p>I need to use the functions <code>spread</code> and <code>gather</code> in the package of <code>tidyr</code>, and I installed this package. I also installed two other packages. However, when I tried to use <code>library(tidyr)</code>, it gave me this long error message, basically saying <code>tidyr</code> was not successfully loaded. By the way, my R is a newer version (4.1). Thanks!</p>
  <pre><code>install.packages(&quot;tidyr&quot;)
  install.packages(&quot;tidyverse&quot;)
  install.packages(&quot;devtools&quot;)
  </code></pre>
  <p>Here's the error message:</p>
