title: How can I ovecome this error in npm install?
body: <p>I'm a beginner programmer, and I'm making a discord bot using node and discord.js. I need a library named <code>canvas</code>, but it doesn't install!</p>
  <p>I programmed and tested this app on my windows pc, then sent it over to my raspberry server. It didn't work, so I tried deleting and installing the library again, but when installing, it gives this error:</p>
  <p>(I'm trying to install it with this command: <code>npm install canvas</code>)</p>
