Deploying Heroku Error

I am in the last steps of deploying Streamlit app in Heroku. I get this error: 3: cannot create ~.streamlit/config.toml: Directory nonexistent.

How can I create config.toml. I using linux.

Here is my file

mkdir -p ~/.streamlit/

echo "\ 
headless = true\n\
port = $PORT\n\
enableCORS = false\n\
" > ~/.streamlit/config.toml

Github repository:


You have a typo in one of your files in the repo (requirments.txt -> requirements.txt), which probably causes the build to fail. But it doesn’t explain why the ~/.streamlit directory is not created.
I have pretty much the same setup (following this guide: streamlit heroku guide), but I haven’t run into the same issue. Check the guide, maybe you missed a step in the heroku setup. Otherwise someone else might be able to help here :slight_smile:

Thanks. As you said the error was unrelated to the typo in requirements.txt file. I still can not figure out.

Hey @shakasom,

Your looks like it’s creating the ~/.streamlit/config.toml file successfully. It’s not formatting that file correctly, however - you don’t need the backslashes and newline character in there. This will work better:

mkdir -p ~/.streamlit

echo "[server]
headless = true
port = $PORT
enableCORS = false
" > ~/.streamlit/config.toml

This isn’t the issue preventing your app from launching, however - that looks like it’s likely due to conflicts in your Pipfile.lock. (A side note: there’s no reason to have both requirements.txt and Pipfile/Pipfile.lock in your project - they’re just two different ways to declare your Python dependencies.) I’d suggest removing both Pipfile and Pipfile.lock, and just using requirements.txt instead, for simplicity’s sake.

I’ve created a sample Streamlit-on-Heroku repo that you can check out if you’re still having trouble. It’s mostly equivalent to what you’ve done, but it specifies a Python 3 runtime, has a simplified requirements.txt, and doesn’t create a credentials file, which is actually unnecessary (though there’s no harm in adding one!).


Thanks, @tim With your example I could deploy the app successful in Heroku.
