Python-slack-sdk: not found slack

[dewei12138]

not found module slack, when i pip3 install slackclient
not import slack

[skasidej]

@dewei12138 I ran into this trouble yesterday with newly installed package slackclient through pip3. It always caused an error with ModuleNotFoundError.

Can you try "import slack" instead of "import slack_client"?

same issue here.

@cnemelka Like I said. slackclient just migrated to v2 and the import package name was changed from "slack_client" to "slack".

[cnemelka]

Traceback (most recent call last):
File "t.py", line 4, in
client = slack.WebClient(token=os.environ['SLACK_API_TOKEN'])
AttributeError: module 'slack' has no attribute 'WebClient'

You'll note this example is from the "migration guide"

It looks like your installed package is out of date. The command in the readme is not enough to upgrade the slackclient package--only enough to install it fresh.

You can check what version of slackclient you have installed by running:

$ pip3 list

You should be able to find slackclient in the list & you might see something like...

Package          Version  
---------------- ---------
...              ...
slackclient      1.3.2
...              ...

As of writing, the latest version is 2.1.0. The above output indicates that my installed is outdated.

When you run pip3 install slackclient, PyPI only cares that any version of slackclient is installed. If you already have an old version installed, that constraint is already met (you already have "any version" of slackclient installed).

So how do I upgrade?

PyPI provides a flag to update the targeted package to its latest version:

$ pip3 install slackclient --upgrade

After that, running pip3 list should show you on the latest version (which is 2.1.0 as of writing).

[cnemelka]

thank you for the response. I performed the upgrade. Still having issues
with module not found. this is the only module currently exhibiting this
behavior.

Any other hints?

Ah, while the PyPI package is called slackclient, you import the module using the name slack:

import slack

# or (for example):

from slack import WebClient

[cnemelka]

That cleared it up. Thank you for your time!

Looks good! Thanks for that @clavin , closing this up for now

[sadaqatullahn]

I am still having the same issue. I am using virtual environment with python 3.6.7 and django 2.2 on ubuntu 18.04.

terminal View:

pip install slack

followed by python manage.py shell_plus
import slack raises following error:

Traceback (most recent call last): File "~/utils/slack_setup.py", line 1, in <module> from slack import WebClient File "~/venv/lib/python3.6/site-packages/slack/__init__.py", line 4, in <module> from slack.web.client import WebClient # noqa File "~/venv/lib/python3.6/site-packages/slack/web/client.py", line 9, in <module> from slack.web.base_client import BaseClient, SlackResponse File "~/venv/lib/python3.6/site-packages/slack/web/base_client.py", line 15, in <module> import aiohttp File "~/venv/lib/python3.6/site-packages/aiohttp/__init__.py", line 6, in <module> from .client import ( File "~/venv/lib/python3.6/site-packages/aiohttp/client.py", line 32, in <module> from . import hdrs, http, payload File "~/venv/lib/python3.6/site-packages/aiohttp/http.py", line 7, in <module> from .http_parser import ( File "~/venv/lib/python3.6/site-packages/aiohttp/http_parser.py", line 15, in <module> from .helpers import NO_EXTENSIONS, BaseTimerContext File "~/venv/lib/python3.6/site-packages/aiohttp/helpers.py", line 223, in <module> @attr.s(frozen=True, slots=True) File "~/venv/lib/python3.6/site-packages/aiohttp/helpers.py", line 225, in ProxyInfo proxy = attr.ib(type=URL) TypeError: attr() got an unexpected keyword argument 'type'

Upon carefully look around, issue persists only on ubuntu. I was unable to replicate the issue with Windows machine.

Getting this error:
```python send.py xyz test

AttributeError: module 'slack' has no attribute 'WebClient'

response = client.chat_postMessage( channel=channel, text=message)
assert response["ok"]

Is there a work-around?

this works for me:

from slack import WebClient

client = WebClient(token=os.environ['SLACK_API_TOKEN'])

I uninstalled the slackclient package and re-installed and now it works. My theory is that some of the dependencies are not correctly resolved on the initial install.
Thank you.

Hi! Same issue here.
I am using version slackclient 2.1.0
Code:
import os
import slack
from slack import WebClient

client = WebClient(token=os.environ["bot_token"])

response = client.chat_postMessage(
channel='#alertas',
text="Test")
assert response["ok"]

But i am getting ImportError: cannot import name 'WebClient' from 'slack'
Any thoughts?

[daverbuj]

I am having the same problem as others have mentioned. I can't do
from slack import WebClient
I get this error:
ImportError: cannot import name 'WebClient'

[zfcuk]

This worked for me: make sure you do not have any files of your own named _slack.py_.
A simple filename change to something more original solved my problem.
This was my setup:

• Windows 10
• Python 3
• latest (2.1) version of slackclient installed

[sang-d]

This worked for me: make sure you do not have any files of your own named _slack.py_.

YES, this is the issue, I've a file name slack.py
Just rename it.

[confiq]

I just got here because I was running old python version by mistake, python3.5.
If you can't find slackclient==2.X, upgrade python 🤞

[Y4rd13]

I not 100% sure if it is a solution, but worked for me: if I don't use my virtual enviroment I can install without issues slackclient
