Our AppImages provide relocatable Python runtimes. Installation is as simple as downloading a single file and changing its mode to executable, e.g. as:

wget https://github.com/niess/python-appimage/releases/download/\
python3.8/python3.8.2-cp38-cp38-manylinux1_x86_64.AppImage
chmod +x python3.8.2-cp38-cp38-manylinux1_x86_64.AppImage

./python3.8.2-cp38-cp38-manylinux1_x86_64.AppImage

This should run Python 3.8 on almost any Linux provided that fuse is available. Note that on WSL1 since fuse is not supported you will need to extract the AppImage as explained hereafter.

The installation mode described previously is enough if you only need vanilla Python with its standard library. However, if you plan to install extra packages we recommmed extracting the AppImage, e.g. as:

./python3.8.2-cp38-cp38-manylinux1_x86_64.AppImage --appimage-extract
mv squashfs-root python3.8
rm -f python3.8.2-cp38-cp38-manylinux1_x86_64.AppImage

export PATH="$(pwd)/python3.8/usr/bin:${PATH}

Then, extra packages can be installed to the extracted AppDir using pip. For example upgrading pip can be done as:

pip install --upgrade pip
