title: Problems on Ruby, gem and redis installation on MacOS
body: <p>I believed that I successfully installed Ruby and RedisDump, however, when I run <code>redis-dump</code> or <code>redis-load</code>, terminal just told me &quot;command not found&quot;. I don't know how to solve this problem.</p>
  <p>The point is I had problem on installation of Ruby and Redisdump before, but I just tried a lot fixing suggestions online, and luckily solved the problem, I believed. So I don't know if I truly properly installed Ruby and RedisDump, or is this just another problem I need to solve?</p>
  <p>To be honest, I am very new to this coding world but I am here to learn, thank you guys!</p>
