sublime出现 unable download.......

I managed to fix this by changing my package settings. I made my osx downloader preference curl, and it works. My preferences are below:

{
    "bootstrapped": true,
    "debug": true,
    "installed_packages":
    [
        "Package Control"
    ],
    "downloader_precedence":
    {
        "linux": [ "curl", "urllib",    "wget" ],
        "osx": [ "curl", "urllib" ],
        "windows": [ "wininet" ]
    },
}

I'm in the process of debugging the python. It looks like it's an error with the way the new urllib is behaving with regards to SSL/HTTPS.

If I had to guess I'd say that it was a problem with the script not running as root, and perhaps not being able to read from the CA file, or write the new ones to it.
