How to solve toml.decoder.TomlDecodeError: Key group not on a line by itself. (line 1 column 1 ...) error when calling streamlit package?

Question

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

(base) C:\>streamlit hello Traceback (most recent call last):

Does anyone know how to solve this error?

Thank you in advance!

Answer 1

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.

Answer 2

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

Answer 3

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!

Answer 4

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.

Answer 5

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

Answer 6

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