title: How to install sicp package module in racket?
body: <p>I'm newbie in programming world. I'm using <strong>ubuntu</strong> OS. I have started my journey with <a href="https://mitpress.mit.edu/sicp/" rel="nofollow">sicp</a> book. I'm working with <code>scheme repl</code>. But suddenly I get stuck with section <a href="https://mitpress.mit.edu/sicp/full-text/book/book-Z-H-15.html#%25_sec_2.2.4" rel="nofollow">2.2.4</a></p>
  
  <p>I'm not able to execute it's example with <code>scheme repl</code>. I tried to run given example of section, I got an error as given below</p>
  
  <pre><code>1 ]=&gt; (define wave2 (beside wave (flip-vert wave)))
  
  ;Unbound variable: wave
  </code></pre>
  
  <p>Even In book, <strong>painter</strong> is given as primitive procedure.
  when I ran it, it thrown an error too</p>
  
  <pre><code>1 ]=&gt; painter
  
  ;Unbound variable: painter
  </code></pre>
  
  <p>I don't know, where I'm doing mistake? can I run these example with <strong>scheme repl</strong>? </p>
  
  <p>I have installed <strong>racket</strong> to solve this problem, But I'm not able to install sicp package for it. I was following these <a href="https://docs.racket-lang.org/sicp-manual/index.html#%28part._.Introduction_to_the_.S.I.C.P_.Picture_.Language%29" rel="nofollow">instruction</a>. Unfortunately I didn't get that well. How can install these package?</p>
  
  <p>Please give your suggestion to  solve this problem. </p>
