Sublime Text 3 插件的安装、升级和卸载，以及安装package control 出现问题解决过程记录

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:

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

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

报错展示：

Package Control: Unable to download https://packagecontrol.io/channel_v3.jsonafter 3 attempts

Emmet: No need to update PyV8

Package Control: Skipping automatic upgrade, last run at 2019-02-26 18:03:18, next run at 2019-02-26 19:03:18 or after

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）
* 科、学、上、网下载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！
