title: from scrapy.selector import selector error
body: <p>I am unable to do the following:</p>
  
  <pre><code>from scrapy.selector import Selector
  </code></pre>
  
  <p>The error is:</p>
  
  <p>File "/Desktop/KSL/KSL/spiders/spider.py", line 1, in 
      from scrapy.selector import Selector
  ImportError: cannot import name Selector</p>
  
  <p>It is as if LXML is not installed on my machine, but it is.  Also, I thought this was a default module built into scrapy.  Maybe not?</p>
  
  <p>Thoughts?</p>
