Python libs dont install on streamlit cloud


I wrote a couple of streamlit games, but ran into deployment issues on streamlit cloud.

There are a couple of python libraries that don’t install on streamlit cloud:

  1. st_lottie
  2. winsound

In my requirements.txt file, I had included the following, but it didnt work (now as well as for an earlier project)

  1. st-lottie
  2. winsound

The github repo link is:shakamoushie/Housie: The Housie / Tambola / Bingo Game (

Would be happy to know the reason for this issue.

Thanks in advance


hey @Shawn_Pereira, thanks for posting.

streamlit lottie works fine on streamlit cloud. You just have to add streamlit-lottie in your requirements.txt and it will be installed.
This is a small app deployed on my server using st-lottie here

And winsound doesnot work on streamlit cloud. The reason behind this is that,

The winsound module provides access to the basic sound-playing machinery provided by Windows platforms . And it comes automatically with windows version of Python. So, on server we dont have anything like windows or its sounds, so that is the reason for not supporting winsound.

There is no st-lottie in pypi, you might be looking for streamlit-lottie

windsound is part of the standard library so there is no way (or need) to install it separately. It is available in Windows only.

Thanks @ilovetensor and @Goyo for the quick response / solution. That was a rookie mistake - using st-lottie instead of streamlit-lottie in the requirements.txt file.

God bless :slight_smile:
