sublime3 mac : Package Control There are no packages available for installation

 如下问题：

 查看控制台：点击 ctrl+`打开控制台 

发现是因为http://packagecontrol.io/channel_v3.json 获取失败，手动下载channel_v3.json文件，下载地址：https://pan.baidu.com/s/1qRgQXiYD2-6MjTb3B3mIBg

下载成功后，放到以下目录

/Users/macname/Library/

修改配置文件

sudo vi /Users/macname/Library/"Application Support"/"Sublime Text 3"/Packages/User/"Package Control.sublime-settings"

替换为以下内容

{
        "bootstrapped": true,
        "channels": [
                "/Users/macname/Library/channel_v3.json"
         ],
        "in_process_packages":
        [
        ],
        "installed_packages":
        [
                "BracketHighlighter",
                "CoffeeScript Ddry Snippets",
                "Color Highlighter",
                "Emmet",
                "LESS",
                "Package Control",
                "Sass",
                "Themr"
        ]
}

再次安装就可以使用了。
