title: Command json-server --watch db.json is not working - it returns"'json-server' command not found"
body: <p>I set a JSON file to use as a little practice database, but I can't run the server.</p>
  
  <p>I've already tried to install (and reinstall) json-server global and locally <code>npm install -g json-server</code> and <code>npm install json-server</code> and then run <code>json-server --watch db.json</code>, but it doesn't work.</p>
  
  <p>I've also tried to set a script in the package.json file <code>"load": "json-server --watch db.json"</code> and run the script <code>node load</code>.</p>
  
  <p>But nothing seems to work and I keep getting in return the message:</p>
  
  <blockquote>
    <p>"'json-server' command not found"</p>
  </blockquote>
  
  <p>or, in Portuguese:</p>
  
  <blockquote>
    <p>"'json-server' não é reconhecido como um comando interno ou externo, um programa operável ou um arquivo em lotes".</p>
  </blockquote>
  
  <p>How can I fix this?</p>
