PW4 How to setup python-webkitgtk and numpy environment in kindle?

[Amias]

How can I set up the environment so I can test and write some apps in kindle?

I tried to install pip on kindle with python3.9, however it seems that HOME variables are very hard to add because everytime I restart kterm I need to do it again, typing those longlong commands.

I've never done that on Kindle, but I see no reason why this wouldn't behave, as the builds are essentially identical:

 139   │ # NOTE: Document pip usage... (*NOT* recommended!)
 140   │ if [ "${COMPILE_PY3}" = "true" ] ; then
 141   │     # NOTE: Technically available on Python 2.7, too, but let's not encourage that...
 142   │     echo ""
 143   │     echo "If you *absolutely* need to, pip can be bootstrapped and updated."
 144   │     echo "This is *NOT* recommended, as it will only be able to install pure-python modules (as there is no available C/C++ compiler)."
 145   │     echo "In addition to that, any extra third-party modules will be *lost* during a Python update!"
 146   │     echo "As for the user site-packages, remember that by default HOME is either in a tmpfs, or, worse, the rootfs..."
 147   │     echo "TL;DR: Don't do this unless you *know* what you're doing!"
 148   │     echo ""
 149   │     echo "That said..."
 150   │     echo "Boostrapping pip:"
 151   │     echo "python${PY3VER} -m ensurepip"
 152   │     echo "Updating pip:"
 153   │     echo "${PY3HOME}/bin/pip${PY3VER} install -U setuptools pip"
 154   │     echo "Symlinking pip into PATH"
 155   │     echo "ln -sf ${PY3HOME}/bin/pip /usr/bin/pip"
 156   │     echo ""
 157   │ fi

(That's from my Kobo Python distrib).
