Why does the simplest streamlit example errors out?

Question

I have the simplest streamlit program

# import module
import streamlit as st

# Title
st.title("Hello GeeksForGeeks !!!")

When I run the code using

streamlit run main.py, I get the following errors:

    SDRRAZAVIPOUR-MAC:[~/PycharmProjects/tool]$ streamlit run main.py
Traceback (most recent call last):
  File "/opt/miniconda3/envs/tool/bin/streamlit", line 8, in <module>

AttributeError: module 'click' has no attribute 'get_os_args'

What am I missing?

Answer 1

Roll back the version of the click package. When I re-cloned our repo and installed the dependencies, it updated click to 8.1.0 and everything died. I uninstalled it, reinstalled 8.0.4, and it ran fine. Check your version of click. Apparently, the get_os_args function has been removed and is not working with streamlit.

Answer 2

Just ran into the same problem. Seems to be related to the most recent version of the click package.

If you uninstall click:

pip uninstall click

and then install the version before the most recent one:

pip install click==8.0.4

it should work again.

Added a click==8.0.4 inside the requirements.txt for a deployment with Heroku. Worked like a charm. – Pharos
