Question

我正在研究Cassandra的文件。但是当我使用＆＃34; pip install cassandra-driver＆＃34;安装cassandra-driver，失败了：

＆＃13;

＆＃13;

如你所见，没有回应我必须通过ctrl + z

来阻止它

我也试过manul安装没有回应

那么错误在哪里？我该如何解决？

Answer 1

我想出来

＆＃34; sudo pip install cassandra-driver＆＃34;

需要一点时间我太急躁了

Answer 2

这需要很长时间，在某些环境中约 10 分钟。你可以使用

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

加快速度。
