Installation of Couchbase Python SDK 3.0.10 failing on python 3.8.5, Ubuntu 22.04

Python SDK
1

Hi, I am not able to install Couchbase Python SDK of version 3.0.10. I am using Ubuntu 22.04 and with pyenv I set global python to 3.8.5.
The requirements are installed:

sudo apt install git-all python3-dev python3-pip python3-setuptools cmake build-essential libssl-dev
sudo apt-get install libssl-dev

I must use Couchbase 3.0.10. I have tried out other python versions (3.9 and 3.10) but all installations fail.
The first error shows that I need to install docutils, but I have them installed in my venv and globally.
Here is the error:

$ python3 -m pip install couchbase==3.0.10

  ERROR: Failed building wheel for couchbase

ERROR: Could not build wheels for couchbase, which is required to install pyproject.toml-based projects

The error at the beginning mentioning ModuleNotFoundError: No module named ‘docutils’ has been tried out. I have this installed both in venv and globally:

$ pip3 install docutils                                                         
Requirement already satisfied: docutils in ./.venv/lib/python3.8/site-packages (0.19)

I was able to install couchbase while using Ubuntu 20 LTS, and since I upgraded to Ubuntu 22.04 LTS it fails. Perhaps someone has encountered this issue and knows what should I do?

Hi @deivydaslipskis – This issue was fixed with PYCBC-1178. Are you able to upgrade to the Python SDK version 3.2.7?

3

Unfortunately, I am not able to upgrade from 3.0.10. So is the 3.0.10 version not supported by Ubuntu 22.04?

@jcasey I tried using the 3.2.7 version, but I seem not to be able to use the get operation to retrieve a document by id. Is using collection mandatory in this version?
Here is an example how I retrieve document by id previously:

from couchbase.cluster import ClusterOptions, ClusterTimeoutOptions, PasswordAuthenticator
from acouchbase.cluster import Cluster

self.cluster = Cluster(
            host,
            options=ClusterOptions(
                authenticator=PasswordAuthenticator(self.user, self.password),
                timeout_options=ClusterTimeoutOptions(
                    query_timeout=self.timeout,
                    kv_timeout=self.timeout,
                    views_timeout=self.timeout,
                    config_total_timeout=self.timeout,
                ),
            ),
        )

self.bucket = self.cluster.bucket(self.bucket_name)

doc_key = "test_user" # this user exists in couchbase database

data = (await self.bucket.get(doc_key)).value

After upgrading I receive this error:

TypeError: object AsyncResult can't be used in 'await' expression

Therefore, I have tried to receive document id in this method:

data = self.bucket.get(doc_key)

This does not error, but I receive this:

print(data)
{}
 type(data)
<class 'AsyncResult'>

The document id is in the Couchbase database for sure, I have tried several over document ids and all return the same empty result.

How should get operation look in 3.2.7 SDK?

Also, I saw get operation examples using collections, but I need to use get operation without using collections.

Hi @deivydaslipskis - We do not officially support Ubuntu 22.04 yet, but the more recent versions of the SDK should work w/ that OS. You can check out the compatibility docs for the 3.0 SDK series here.

When working with an SDK that is compliant with an SDK API >= 3.0, you need to do KV operations from a collection object. Even if you are not using collections. See the CRUD operation docs here. The full example can be found on Github here. I have included a small snippet of the doc’s example below.

from acouchbase.cluster import Cluster, get_event_loop
from couchbase.cluster import ClusterOptions
from couchbase.auth import PasswordAuthenticator

async def get_couchbase():
    cluster = Cluster(
        "couchbase://localhost",
        ClusterOptions(PasswordAuthenticator("Administrator", "password")))
    bucket = cluster.bucket("travel-sample")
    await bucket.on_connect()

    return cluster, bucket

async def kv_operations(collection):
    key = "hotel_10025"
    res = await collection.get(key)
    hotel = res.content_as[dict]
    print("Hotel: {}".format(hotel))

    hotel["alias"] = "Hostel"
    res = await collection.upsert(key, hotel)
    print("CAS: {}".format(res.cas))

    # handle exception
    try:
        res = await collection.get("not-a-key")
    except DocumentNotFoundException as ex:
        print("Document not found exception caught!")

loop = get_event_loop()
cluster, bucket = loop.run_until_complete(get_couchbase())
# get a reference to the default collection, required for older Couchbase server versions
cb_coll_default = bucket.default_collection()

loop.run_until_complete(kv_operations(cb_coll))

Hi @jcasey - Seems to be working, thanks!
