sublime text3 可以使用 Package Control 安装其他插件，来提高开发效率。所以我们先要知道Package Control是怎么安装的。 1、安装Package Control Package Control官网安装：https://packagecontrol.io/installation Simple：
The simplest method of installation is through the Sublime Text console. The console is accessed via the ctrl+` shortcut or the View > Show Console menu. Once open, paste the appropriate Python code for your version of Sublime Text into the console.
首先通过快捷键 ctrl+` (mac电脑esc下面的按键) 或者 View > Show Console 打开控制台(注：如果安装有QQ输入法等快捷键有冲突的情况时候，可以先修改相关软件功能快捷键的设置)，输入以下代码，enter即可.
import urllib.request,os,hashlib; h = \'6f4c264a24d933ce70df5dedcf1dcaee\' + \'ebe013ee18cced0ef93d5f746d80ef60\'; pf = \'Package Control.sublime-package\'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( \'http://packagecontrol.io/\' + pf.replace(\' \', \'%20\')).read(); dh = hashlib.sha256(by).hexdigest(); print(\'Error validating download (got %s instead of %s), please try manual install\' % (dh, h)) if dh != h else open(os.path.join( ipp, pf), \'wb\' ).write(by)
2、自动安装package control 失败
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:
Click the Preferences > Browse Packages… menu
Browse up a folder and then into the Installed Packages/folder
Download Package Control.sublime-package and copy it into the Installed Packages/ directory
Restart Sublime Text
3、不能进行package control:install package,以及后续插件安装
报错展示：
