I have the same problem and I seen that is a common issue in the web.

I think this environment variable issue, can be easily fixed by just adding

import os

os.environ['DISPLAY'] = ':0

to the code, imo

👉 I am using:

• Ubuntu 22.04.3 LTS (Jammy Jellyfish, in Google Colab)
• Python 3.10.12
• pywhatkit-5.4.1

I am able to fix the error messages by using virtual display. However, my WhatsApp didn't receive any messages. I believe it is related to this issue sendwhatmsg_instantly() sometimes not sending message #308. If so, I don't know how to make this line of code web.open(f"https://web.whatsapp.com/send?phone={phone_no}&text={quote(message)}"), which launches a web browser, work in Google Colab. Hope anyone here can help. Thanks!
