Sublime Text 3安装插件报错：ImportError: No module named 'package_control'

Hey there, let's work through this frustrating Package Control issue you're hitting. That import error almost always means there's a corrupted or incomplete Package Control installation—even if you've reinstalled it already. Here's how to fix it step by step:

Step 1: Fully Clean Up Package Control Residues #

First, we need to wipe out all existing traces of Package Control to avoid leftover corrupted files:

• Close Sublime Text 3 completely (make sure it's not running in the background).
• Open File Explorer and navigate to C:\Users\Tobias\AppData\Roaming\Sublime Text 3\Installed Packages. Delete the Package Control.sublime-package file here.
• Next, go to C:\Users\Tobias\AppData\Roaming\Sublime Text 3\Packages. If you see a folder named Package Control, delete it too.

Step 2: Reinstall Package Control Manually #

The manual installation method is more reliable than using the automatic script sometimes, especially if previous installs left gunk:

• Launch Sublime Text 3, then press `Ctrl + `` (the backtick key, right above your Tab key) to open the console.
• Paste the official ST3 installation code into the console and hit Enter. Wait for the installation to finish (you'll see a confirmation message in the console).
• Restart Sublime Text 3 once done.

Step 3: Check Windows Firewall & Proxy Settings #

Windows 8's firewall might be blocking Package Control from accessing the plugin repositories:

• Open Control Panel > Windows Firewall > Allow an app or feature through Windows Firewall.
• Find Sublime Text 3 in the list, make sure both "Private" and "Public" network access are checked. Click OK to save.
• If you use a proxy server, configure it in Sublime's settings:
  1. Go to Preferences > Settings to open the user settings file.
  2. Add these lines (replace with your proxy details if needed):

     "http_proxy": "http://your-proxy-host:port",
     "https_proxy": "http://your-proxy-host:port"
     

  3. Save the settings and restart Sublime. If you don't use a proxy, make sure there are no proxy-related lines in your user settings.

Step 4: Clear Sublime's Cache (If Needed) #

If the error still pops up, corrupted cache files might be the culprit:

• Close Sublime Text 3.
• Navigate to C:\Users\Tobias\AppData\Roaming\Sublime Text 3\Cache and delete all files and folders inside this directory.
• Restart Sublime and try installing a plugin again.

Why This Happens #

Most of the time, this error occurs when Package Control's core files get corrupted during an install/update, or when leftover files from a previous install conflict with the new one. Fully cleaning up before reinstalling ensures you start with a fresh, working copy.
