Why can't I install Cassandra-driver

Question

I am studying Cassandra by its document. But when I use "pip install cassandra-driver" to install cassandra-driver ,failed like this:

weikairen2@weikairen2-virtual-machine:~$ pip install cassandra-driver

weikairen2@weikairen2-virtual-machine:~/cassandra-driver-3.7.0$ python setup.py build

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

I also tried manul install no response again

So where is the error? How can I fix it?

Answer 1

I figure out

"sudo pip install cassandra-driver"

it takes a little long time I was just too impatient
