I just installed the streamlit package. When I try to run 'streamlit hello' I get the following error:

Does anyone know how to solve this error?

Thank you in advance!

    Seems like its uphappy with your config file, did you edit it? if you did it most likely is something about how it was edited. could you edit your entry to include the contents of the config toml based file. – LhasaDad Jan 19 '20 at 15:33
  • there is a toml validator here: https://www.toml-lint.com/ Try feeding it the contents of your config file. – LhasaDad Jan 19 '20 at 15:34
  • I have the same error. How do I find the config toml based file? – bjornvandijkman Jan 21 '20 at 10:53

I also got the same error while I tried to run the 'streamlit' command.

So, what I did is track in the code entirely to see from where I can find this 'config.toml' and simply deleted the file.

The path for 'config.toml' file in Windows is: C:users/{username}/.streamlit/config.toml

Delete this file and it will solve the error.

Just delete the config.toml file which can be found in the directory where you have installed streamlit.

If you are not able to locate your .streamlit directory

Run streamlit cache clear

Output :

Nothing to clear at {Username}\{path}\.streamlit\cache.

You will get output similar to this which will tell you where is your .streamlit directory exactly.

Take this path before the cache part

cd {Username}\{path}\.streamlit

You'll be able to see config.toml here just delete that file.

The Streamlit forum has this discussion topic: https://discuss.streamlit.io/t/toml-docoder-error/1400/10 that discusses this. Hope this helps!

delete the content of config.toml file which is in C:\Users\username.streamlit

Do you have a setup.sh file? What's the content inside it? maybe you will just have to put the content of setup.sh everything in 1 line like this

[server]\nheadless = true\nenableCORS=false\nport = \n

my problem was similar, not exactly like this. so I hope it works!
