Streamlit native multipage support not working

[Huvinesh-Rajendran-1]

Summary

I followed the streamlit documentation on implementing a multipage app natively and structured my streamlit project directory as such.

main_page.py :

import streamlit as st

st.markdown("# Main page 🎈")
st.sidebar.markdown("# Main page 🎈")

pages/page_2.py :

import streamlit as st

st.markdown("# Page 2 ❄️")
st.sidebar.markdown("# Page 2 ❄️")

pages/page_3.py :

import streamlit as st

st.markdown("# Page 3 🎉")
st.sidebar.markdown("# Page 3 🎉")

The output :

May I know what is wrong here ? Thanks.

Hi @Huvinesh-Rajendran-1, welcome to the forum!

From the screenshots you’ve shared, it looks like your app is structured correctly What version of Streamlit is it using? You can check via streamlit version in the terminal or st.write(st.__version__) in main_page.py.

Support for multipage apps was added in version 1.10.0, so I’d start by confirming the version is >=1.10.0.

Yeah the issue was with the version. I installed streamlit using conda, seems like conda has support only upto version 1.9.0 as of now. I reinstalled it using pip, thanks.

Hmm, I don’t think that’s the case (?) The latest v1.19.0 and prior versions are available in the conda-forge channel:

Ah I see, I checked, there was some issues with one of the libraries during installation hence it installed version 1.9.0 for me. I checked and installed back to 1.19.0. Thanks for the heads up.
