Hi @sagar1412, welcome to the Streamlit community!!
You’re running into the error because you’re trying to install Python packages using packages.txt. Any Python packages to be installed from PyPi should instead be in requirements.txt. To get it working:
@pawan_gupta freeglut3-dev is a binary package, not a pypi package.
If you want to install a binary package, you have to put in into the packages.txt file.
If you need help, please provide a link to your github repo.
I think you will have better luck if you create a new topic. When you do, reboot (or delete and redeploy) your app, then copy and paste the entire log into a codeblock for us to read. It will save us time either forking and trying to deploy your app, or trying to catch a small detail in the environment setup files on-sight.
I’ll close this thread since it gets a little messy on piggy-backed threads resolving everyone’s different environment.
