Why can't I install Cassandra-driver
<p>I am studying Cassandra by its document.
But when I use "pip install cassandra-driver" to install cassandra-driver ,failed like this:</p>

<p>as you can see,there is no response 
and I have to stop it by ctrl+z</p>

<p>I also tried manul install 
no response again</p>

<p>So where is the error? How can I fix it?</p>

<p>I figure out</p>

<p>"sudo pip install cassandra-driver"</p>

<p>it takes a little long time
I was just too impatient </p>
