title: scrapy on Macbook error: Module 'tutorial' already exists
body: <p>After installation of scrapy,
  I use 'scrapy startproject tutorial' to start but it shows below:</p>
  
  <pre><code>Icelesss-MacBook-Pro:tutorial iceless$ scrapy startproject tutorial
  Error: Module 'tutorial' already exists
  </code></pre>
  
  <p>When I just type import scrapy, it shows:</p>
  
  <pre><code>Icelesss-MacBook-Pro:~ iceless$ import scrapy
  -bash: import: command not found
  Icelesss-MacBook-Pro:~ iceless$ scrapy.item
  -bash: scrapy.item: command not found
  Icelesss-MacBook-Pro:~ iceless$ create scrapy.Item
  -bash: create: command not found
  Icelesss-MacBook-Pro:~ iceless$ items.py
  -bash: items.py: command not found
  Icelesss-MacBook-Pro:~ iceless$ cd tutorial
  Icelesss-MacBook-Pro:tutorial iceless$ import scrapy
