如何在Windows上使升华文本读取PYTHONPATH环境变量

有几个在线资源介绍如何使SublimiteText read PYTHONPATH变量在Windows开始菜单>控制面板>系统>高级设置>环境变量中指定

然而，它们都没有清楚地描述如何在Windows中定制Sublime。我们如何做到这一点？

env需要是一个JSON对象，如果您愿意，也可以是一个字典，如下所示：

  "env":
    {"PYTHONPATH":"/usr/local/lib/python:/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages"},

{
"path": "/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin",
"env":{"PYTHONPATH":"/usr/local/lib/python:/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages"},
"cmd": ["python", "-u", "$file"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}

如果使用Python3.x，则需要编辑Python3.sublime-build（首选项>浏览包>Python3）
看起来像这样：

  "env":
    {"PYTHONPATH":"/usr/local/lib/python:/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages"},

{
"path": "/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin",
"env":{"PYTHONPATH":"/usr/local/lib/python:/usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages"},
"cmd": ["python", "-u", "$file"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}

我们应该将这个JSON对象包含到哪个配置文件中？
