Check the installed python<\/p>\n

satria@teddy:~$ pip -V
\npip 22.0.2 from \/usr\/lib\/python3\/dist-packages\/pip (python 3.10)<\/p>\n

it seems I already installed python 3. but when I want to find out the location with ‘whereis python’, it showed up nothing<\/p>\n

satria@teddy:~$ whereis python
\npython:<\/p>\n

so use ‘whereis python3’ instead<\/p>\n

satria@teddy:~$ whereis python3
\npython3: \/usr\/bin\/python3 \/usr\/lib\/python3 \/etc\/python3 \/usr\/share\/python3 \/usr\/share\/man\/man1\/python3.1.gz<\/p>\n

I need to symlink python 3 to use just ‘python’ like this
\nsatria@teddy:~$ sudo ln -s \/usr\/bin\/python3 \/usr\/bin\/python<\/p>\n

then I can use like this
\nsatria@teddy:~$ whereis python
\npython: \/usr\/bin\/python<\/p>\n

Install streamlit with python3 virtual environment (venv)
\nref: https:\/\/docs.streamlit.io\/get-started\/installation\/command-line<\/p>\n

create a new directory.\u00a0 for\u00a0 example ‘streamlit’
\nsatria@teddy:~$ cd Documents\/projects\/python\/streamlit\/<\/p>\n

then go into the dir. make sure you already have python3-venv package. if not install it
\nsatria@teddy:~\/Documents\/projects\/python\/streamlit$ sudo apt install python3.10-venv<\/p>\n

then use python3-venv like this:
\nsatria@teddy:~\/Documents\/projects\/python\/streamlit$ python -m venv .venv<\/p>\n

Activate the virtual environment
\nsatria@teddy:~\/Documents\/projects\/python\/streamlit$ source .venv\/bin\/activate
\n(.venv) satria@teddy:~\/Documents\/projects\/python\/streamlit$<\/p>\n

install streamlit with pip in the venv
\n(.venv) satria@teddy:~\/Documents\/projects\/python\/streamlit$ pip install streamlit
