python - Datastax cassandra-driver (python) 导入失败

Question

导入 datastax cassandra-driver(python) 时出现以下错误

错误

File "cassandra.py", line 1, in <module>
    from cassandra.cluster import Cluster
File "/home/vagrant/cassandra.py", line 1, in <module>
    from cassandra.cluster import Cluster
ImportError: No module named cluster

这是代码

from cassandra.cluster import Cluster
print dir(cassandra.cluster)
cluster = Cluster()
session = cluster.connect('userspace')
rows = session.execute('SELECT user_name, gender FROM users')
for user_row in rows:
    print user_row.user_name, user_row.gender

Answer 1

嗯，看起来名字有冲突。您的脚本是cassandra.py，因此它是驱动程序的模块。尝试重命名您的脚本（不要忘记删除它.pyc）并重试

Answer 2

安装CQL 交互终端：

sudo pip install cqlsh

Answer 3

我试过这个，它适用于我的情况： python -m pip install `

例如： python -m pip install cassandra-driver
