    I’m having trouble installing both python 2 and python 3 in my environment. The installation instructions mention that “extra space savings arise if you download the combined release…” which sounds great. Looking at the installation script, it implies that there should be a single archive containing the combined release. The last step below is what I’m referring to.

    cd $RELEASE_DIR; ls -ld python27 python36 both
    # based on the results of the ls, run one or more of these commands
    cd $RELEASE_DIR/python27; bin/install_all_packages
    cd $RELEASE_DIR/python36; bin/install_all_packages
    cd $RELEASE_DIR/both; bin/install_all_packages

    So this implies there should be an archive containing the combined release called:


    However, the only archives available to download are:


    Am I misunderstanding the directions? If I do what it says, won’t I will just end up with two separate installations without any modules shared between them?
