为什么我不能安装Cassandra驱动程序

Question

我正在根据它的文档研究Cassandra。但是当我使用"pip install cassandra-driver“安装cassandra-driver时，失败的原因如下：

​

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

^Z
[2]+  已停止               python setup.py install
weikairen2@weikairen2-virtual-machine:~/cassandra-driver-3.7.0$ python setup.py build

​

如您所见，没有响应，我必须通过ctrl+z停止它

我还再次尝试了手动安装无响应

那么错误在哪里呢？我怎么才能修复它？

Answer 1

我想通了

"sudo pip install cassandra-driver“

这花了我很长时间，我太不耐烦了

Answer 2

这需要很长的时间，在某些环境下大约需要10分钟。您可以使用

$ # installing from source
$ CASS_DRIVER_BUILD_CONCURRENCY=8 python setup.py install
$ # installing from pip
$ CASS_DRIVER_BUILD_CONCURRENCY=8 pip install cassandra-driver

来加快速度。
