title: can not install cocos2d
body: <p>I tried to install <strong>cocos2dx3.5</strong> on <strong>Ubuntu12.04</strong></p>
  
  <pre><code>$ cd /tmp &amp;&amp; mkdir cocos2dxInstall
  $ unzip cocos2d-x-3.5.zip -d /tmp/cocos2dxInstall
  $ cd /tmp/cocos2dxInstall/cocos2d-x-3.5
  $ ./download-deps.py
  </code></pre>
  
  <p>After I downloaded all the dependencies:</p>
  
  <pre><code>$ cd build &amp;&amp; mkdir linux_build &amp;&amp; cd linux_build
  $ cmake ../..
  $ make 
  </code></pre>
  
  <p>waiting a very long time for them to compile, I ran:</p>
  
  <pre><code>$ cd ../..
  $ cd tools/cocos2d-consle/bin
  $ python install.py
  </code></pre>
  
  <p>Unfortunately, it raised an error:</p>
  
  <pre><code>Starting the installation for Cocos2D console
  Downloading...
  Installing...
  Traceback (most recent call last):
    File "install.py", line 74, in &lt;module&gt;
      with TarFile.open(download_path) as tar:
    File "/usr/lib/python2.7/tarfile.py", line 1665, in open
      raise ReadError("file could not be opened successfully")
   tarfile.ReadError: file could not be opened successfully
  </code></pre>
  
  <p>How do I fix it?</p>
