TL;DR: Install Package Control manually. Add the proxy settings to the configuration file as described in step 2 below.
Today I've had to install Sublime Text 3 again on a new computer. Package control didn't want to install due to my proxy settings (I was getting a 407 error code - Proxy authentification required). I managed to do it with two simple steps:
Install Package Control manually. At the time of writing this post, the process is simple:
- 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
Set the proxy coordinates in the settings:
Click the Preferences > Browse Packages… menu
Add the following JSON entries to the file:
http_proxy- your proxy address/port (x.x.x.x:port)
proxy_username- the user name for authentication
proxy_password- the password
Note: Your proxy password will be stored in plain text so you might want to set up file permissions...
