I am running for the first time & encountered an error, which says (Error: --browser.gatherUsageStats option requires an argument) after I run the command streamlit run app.py --browser.gatherUsageStats in my terminal.
Can someone tell me where am I wrong?
Hi @Learner, welcome to the forum 
I believe you are missing the argument for the flag, it should be
streamlit run app.py --browser.gatherUsageStats false

@andfanilo I ran the command as you’ve directed , but after that nothing appears in my terminal, the cursor simply blinks. Where can be the issue?
Ah…this is more troublesome 
Do you have the same behavior if you run streamlit hello ?
Otherwise what’s your Streamlit version / Python version / Are you using Conda/Pip/Pipenv / OS version ? How did you install Streamlit on your system ?
@andfanilo yeah I find the same behaviour while running streamlit hello
Conda environment
Python 3.7.7
Streamlit, version 0.61.0
Windows 10
pip install streamlit is the only command to install streamlit
Hmmm, I honestly don’t have an idea for now …are you in a separate conda env by the way ? maybe the streamlit command you installed is not in the same environment as the one you think it is so tries to rely on the wrong dependencies …
You could try creating a new conda environment with a downgraded Streamlit like 0.60.0 ?
Maybe your antivirus is blocking the python.exe from your separate environment (that…actually happened once to me) ?
If you can try again with the procedure from the FAQ…maybe it’ll give you some more ideas
I was bogged down with a similar issue. I fixed it by running a pip install of streamlit into the very directory that the app is in.
