sublime text3 安装package control 出现问题解决过程记录

1、安装package control 失败

通过最简单的自动安装 package control 失败（详见package control官网）.

报错展示：

File "./python3.3/urllib/request.py", line 1248, in do_open

........

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File "<string>", line 1, in <module>

  File "./python3.3/urllib/request.py", line 156, in urlopen

.........

解决方式：显然自动安装已经不行，按照官网进行手动安装即可。

If for some reason the console installation instructions do not work for you (such as having a proxy on your network), perform the following steps to manually install Package Control:

1. Click the Preferences > Browse Packages… menu
2. Browse up a folder and then into the Installed Packages/folder
3. Download Package Control.sublime-package and copy it into the Installed Packages/ directory
4. Restart Sublime Text

2、不能进行package control:install package,以及后续插件安装

报错展示：

解决：详见 https://github.com/wbond/package_control/issues/1408

* 下载Package Control手动安装（详见第一个问题）
* ***下载channel_v3.json，记事本打开，找到"schema_version": "3.0.0".把3.0.0改成2.0，保存
* 把channel_v3.json放到一个安全不会被删除的目录下。
* subline菜单栏中的prefrences->package setting->Package control->setting-user。在{}中加入
"channels":
[
"channel_v3的存放目录完整路径"
],
* 保存后，ctrl+shift+p,正常安装就成了。
之前安装失败原因：channel_v3.json被墙了，无法下载下来。

完美解决！
