Aerospike Python Client 2.0: Support for Python 3


#1

Posted on March 7, 2016

The 2.0 version of the Aerospike Python client is a major release: it adds support for Python 3. Therefore, the client software is now compatible with Python versions 2.6, 2.7, 3.4 and 3.5. For those of you migrating your application from Python 2 to Python 3, there are a few key differences between the two versions to keep in mind as you work through porting the software to the next version.

Because of the non-backward compatible python and python3 issues, I am typically installing python2 as ‘python’ and python3 as ‘python3’. I am not using ‘virtualenv’ but I do have pip3 installed.

When I run ‘pip3 install aerospike’ ( as root ) I get the following:

Python.h comes from the python-dev package. Use brew, or however you installed python to install the python3-dev package.
