title: Nvm node install checksums do not match because of a forward slash
body: <p>I'm learning to use nvm to manage node versions, but all my installations fail with the error: checksums do not match.</p>
  
  <p>The only difference is the '\' in the found checksum:</p>
  
  <blockquote>
    <p>Computing checksum with shasum -a 256 Checksums do not match:
