Я установил пакет SublimeANSI , отредактировал оба файла Makefile и Python sublime-build, используя PackageResourceViewer .
Makefile:

{
    "shell_cmd": "make",
    "file_regex": "^(..[^:\n]*):([0-9]+):?([0-9]+)?:? (.*)$",
    "working_dir": "${folder:${project_path:${file_path}}}",
    "selector": "source.makefile",
    "syntax": "Packages/Makefile/Make Output.sublime-syntax",
    "keyfiles": ["Makefile", "makefile"],

    /*  add target and syntax */
    "target": "ansi_color_build",
    "syntax": "Packages/ANSIescape/ANSI.tmLanguage",

    "variants":
    [
        {
            "name": "Clean",
            "shell_cmd": "make clean"
        }
    ]
}

Python:

{
    "shell_cmd": "python -u \"$file\"",
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python",

    "env": {"PYTHONIOENCODING": "utf-8"},

    /*  add target and syntax */
    "target": "ansi_color_build",
    "syntax": "Packages/ANSIescape/ANSI.tmLanguage",


    "variants":
    [
        {
            "name": "Syntax Check",
            "shell_cmd": "python -m py_compile \"${file}\"",
        }
    ]

}

Но по какой-то причине вывод все еще не может декодировать ANSI:
