title: unable to locate APT file on Mac when installing libxml2
body: <p>I'm trying to install libxml2 on my Mac as R studio on Microsoft Azure is unable to install certain libraries like Tidyverse and Quanteda without XML library. So, when I ran the command below on Terminal, I got the following prompt. I did some googling and found that Mac doesn't have an APT file in java. I found couple of answers of similar questions asked earlier on SO, but they didn't really answer this question. How should I fix this? Thanks.</p>
  <pre><code>sudo apt install libxml2_dev  
  
  
  Unable to locate an executable at &quot;/Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home/bin/apt&quot; (-1)
  </code></pre>
