Problems installing python package

Python SDK
1

I am attempting to install the python API as per the instructions here https://docs.couchbase.com/python-sdk/current/start-using-sdk.html. These suggest the package should have all dependencies included, but the output suggests this is not the case.

On windows (python 2.7)

C:\Python27>pip install couchbase

The experience on centos 7 is much the same

(couchbase)towler@buildlocal:~$ pip install couchbase
You are using pip version 7.1.0, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Hi

Please follow the detailed instructions on the page you linked.

On Unix based systems, you need to install libcouchbase to build Couchbase Python Client V2. We have developed a system for building all necessary dependencies for our upcoming V3 Alpha but that is pending release.

On Windows, we only support Python>3.6 (see https://docs.couchbase.com/python-sdk/current/compatibility-versions-features.html), but you should be able to run ‘pip install couchbase’ and Pip will pull in a wheel with all the necessary dependencies.

Hope that helps,

Thanks,

Ellis

Thanks for the quick reply, I now have this working on windows.

Having searched the page I suggest it might be helpful for others if the page I linked to could gain a mention of either the minimum python version or a link to a page listing this. I searched for both “3” and “platform” and found no results.

Hi Towler,

No problem. Glad to hear we got you up and running!

Thanks for your feedback re the documentation - I will file a documentation issue to make the requirements clearer.

Thanks,

Ellis

Hi @Nikhil_MVS - Thanks for the additional comments!

I wanted to also point out that we have been able to update the documentation with further details on installing. Both the Couchbase documentation and the Github README reflect details on how to install the Python SDK on various OSes.

I hope this helps.
