Using slack API: "Module slack has no attribute WebClient "

Question

I try to use the slack API to send a message to a workspace, I found this piece of code on their docs but I have an issue with the module slack. This is the code I used:

import os
import slack

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

response = client.chat_postMessage(
    channel='#viktor',
    text="Hello world!")
assert response["ok"]
assert response["message"]["text"] == "Hello world!"

I have put my app token but it does not recognize WebClient... any idea?

The code looks correct. Are you sure you have the correct package and version installed? should be this: https://github.com/slackapi/python-slackclient — Erik Kalkoken, Aug 01 '19 at 13:30
To upgrade to newest version do: `pip install slackclient --upgrade` — Erik Kalkoken, Aug 01 '19 at 13:31
You can also run `pip show slackclient` to see what you got. Should be V2.1.0 — Erik Kalkoken, Aug 01 '19 at 13:33

Make sure you don't have any user files named slack slack_client.
A simple filename change to something more original solved my problem.

This was my setup:

MacOs HS
Python 3.7
latest (2.4) version of slackclient installed

I use python-slack-sdk, it works great. See https://github.com/slackapi/python-slack-sdk#uploading-files-to-slack

To install, run pip3 install slack_sdk

To upload a file

import os
from slack_sdk import WebClient
from slack_sdk.errors import SlackApiError

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

try:
    filepath="./tmp.txt"
    response = client.files_upload(channels='#random', file=filepath)
    assert response["file"]  # the uploaded file
except SlackApiError as e:
    # You will get a SlackApiError if "ok" is False
    assert e.response["ok"] is False
    assert e.response["error"]  # str like 'invalid_auth', 'channel_not_found'
    print(f"Got an error: {e.response['error']}")
