Question

我正在尝试使用Datomic设置Cassandra，当我运行命令cqlsh -f ~/datomic/bin/cql/cassandra-user.cql -u uname -p pword时，我收到错误消息

Error: No module named cassandra

我已经使用pip install cassandra-driver使用export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages尝试将驱动程序所在的路径放在我的PYTHONPATH上来安装驱动程序。我甚至将驱动程序复制到我路径中已列出的目录之一。没运气。有人可以帮助我克服这个障碍吗？

Cassandra安装了自制软件/usr/local/Cellar/cassandra/2.1.2/

Datomic在这里 ~/datomic

cassandra-driver在这里 /usr/local/lib/python2.7/site-packages

看起来你正在尝试使用mac系统python发行版，是吗？虽然没有错，但建议单独保留系统分发并使用brew install python安装单独的python。然后尝试使用pip install cql安装cqlsh，同时确保使用brew pip版本（使用which pip检查 - ＆gt;应指向/ usr / local）。

怎样才能让Cassandra-driver进入PYTHONPATH？
