Streamlit: command not found

Hello.

I created an application in Render

I tried a deployment with my sources in my GitHub: h

But it failed.

I have the error “streamlit: command not found”.

Yet when I look at the logs, streamit was installed, as stated in the requirements.txt file:

collecting mdurl~=0.1 (from markdown-it-py>=2.2.0->rich<14,>=10.14.0->streamlit->-r requirements.txt (line 1))
Downloading streamlit-1 42.2-py2.py3-none-any.whl (9.6 MB)

Render’s order is: “streamlit run app.py --server.port $PORT --server.address 0 0 0 0”

Why doesn’t he find himself in bed?

Should something be reported in environmental variables?

If so how?

Is Streamlit properly installed on the Cloud server?

Or should it be installed on my PC in premises?

Thank you in advance.
Sincerely.
