Cannot install due to AttributeError: LCB_SUBDOC_MULTI_FAILURE

[sublee]

I tried to install couchbase-2.2.2 and couchbase-python-cffi@2.x in my PyPy environment. But the installation was failed due to an error:

$ pip install couchbase
Collecting couchbase
  Using cached couchbase-2.2.2.tar.gz
Installing collected packages: couchbase
  Running setup.py install for couchbase ... done
Successfully installed couchbase-2.2.2
You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

$ cd ~/couchbase-python-cffi
$ python setup.py install

My PyPy environment is:

Python 2.7.10 (5.0.1+dfsg-4, Apr 08 2016, 00:22:14)
[PyPy 5.0.1 with GCC 5.3.1 20160407]

What is the libcouchbase version? LCB_SUBDOC_MULTI_FAILURE was introduced in 2.5.6

[sublee]

The version is 2.6.2-132610. Can't I use this version?

[avsej]

Yes, you can. Maybe problem in FFI bindings. @mnunberg could you take a look?

[mnunberg]

I'm trying to fix this, but you should use the exact version of the Python client as mentioned in the README. In this case, 2.0.0-beta.

Newer is not always better, because this module relies on the internals of the Python SDK. You'll get weird errors otherwise

[mnunberg]

btw, what kind of features are you planning to use with this library? the cffi module hasn't been updated very recently - mainly because there's been a few changes internally within the library.

[sublee]

@mnunberg I need the sub-document API, N1QL, and many awesome features of the latest Couchbase.

My project depends on couchbase-2.2.2 for CPython with Couchbase Server 4.6. Now I'm going to move to PyPy but am hindered by this issue.

So, currently, there's no way to use latest Couchbase features in PyPy?

[mnunberg]

It’ll likely take a while (weeks-months) until I’m able to implement all those bits in cffi :(

@mnunberg If you need any of my help, I will do something for you. Anyway, I have appreciated you for developing the Python client library and this binding.

[sublee]

Do you have any plan to support the latest libcouchbase by couchbase-python-cffi?

[paulaangb]

Do we have any support for latest python version? We can't run pypy mode for our project!
