Do you have a config file at any of these locations?
[your project folder]/.streamlit/config.toml
~/.streamlit/config.toml
If so, my guess is thereโs a syntax error in one of those. Probably something that looks like foo=
(with nothing on the right side). If you see something like that, please remove it from the config file and try running Streamlit again.
(And in the meantime, Iโve opened a bug on our end since we should throw a clearer error message in that case!)
