我正在尝试执行./cqlsh。但它给出了以下错误：
Python Cassandra driver not installed, or not on PYTHONPATH.
You might try "pip install cassandra-driver".
Python: /usr/local/bin/python
Module load path: ['/home/ubuntu/Downloads/apache-cassandra-3.11.2-bin/apache-cassandra-3.11.2/bin/../lib/six-1.7.3-py2.py3-none-any.zip', '/home/ubuntu/Downloads/apache-cassandra-3.11.2-bin/apache-cassandra-3.11.2/bin/../lib/futures-2.1.6-py2.py3-none-any.zip', '/home/ubuntu/Downloads/apache-cassandra-3.11.2-bin/apache-cassandra-3.11.2/bin/../lib/cassandra-driver-internal-only-3.11.0-bb96859b.zip/cassandra-driver-3.11.0-bb96859b', '/home/ubuntu/Downloads/apache-cassandra-3.11.2-bin/apache-cassandra-3.11.2/bin', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']
Error: can't decompress data; zlib not available我已经安装了python，zlib，cassandra驱动程序，但是上面的错误仍然存在。

如果您下载了cassandra的tarball版本并将其正确解包，那么我只能假设您的副本已损坏/不完整。
今年早些时候，我修改了apache网站（cassandra-15466）上的cassandra安装说明。
如果你在一个干净的ubuntu18.04或20.04服务器上按照安装说明进行操作，它将第一次工作，每次--https://cassandra.apache.org/doc/latest/getting_started/installing.html#installing-二进制tarball。干杯！
