  • Hi Corinne,

    It looks like you're trying to install datamatrix globally, but without root access. (I don't know exactly why that happens, because a local installation should be the default.) But in any case, you should be able to install datamatrix (and other dependencies) without root access like so:

    pip install --user python-datamatrix


  • thak you very much ! I will try again ...My husband Christopher had installed Windows for my experience :'( but I prefer Linux ;)
    Have a good sleep !
