Before you start building apps with Streamlit you will need to have a working installation of Streamlit on your system. If you don't have it set up yet, the following steps will guide you through the process, whether you're on Windows, macOS or Linux.
If you don't have an installation of Python 3, you will need to install one first. You can download installers for Python 3 from the Python homepage. Once installed, you should be able to follow the instructions below.
Setup your Project Environment & Install Streamlit
To keep your projects self-contained, we recommend created a new virtual environment for each project. If you're just learning, you can create a virtual environment for working through the tutorials in.
If you later want to create a new folder for a different project, you can just repeat this process.
Below are the instructions for creating a new project folder, creating a virtual environment and installing Streamlit, on Windows, macOS and Linux.
- Windows
- macOS
- Linux
> mkdir myapp/
> cd myapp
> python -m venv venv
> venv\Scripts\activate.bat
(venv)> pip install streamlit
$ mkdir myapp/
$ cd myapp
$ python -m venv venv
$ source venv/bin/activate
(venv)$ pip install streamlit
$ mkdir myapp/
$ cd myapp
$ python -m venv venv
$ source venv/bin/activate
(venv)$ pip install streamlit
Once complete, start python by running python from the command line. You should then be able to import Streamlit with the following.
import streamlit
If that import works Streamlit is correctly set up & you're now ready to start building apps with Streamlit.
