能否一次性卸载所有VSCode插件/扩展？修复HTML标记异常并重置编辑器

Absolutely, this is totally doable—and it’s actually a go-to troubleshooting step when VS Code starts acting wonky (like your HTML markup glitches) due to conflicting or misbehaving extensions. Here’s how to pull it off safely:

Step 1: Uninstall All Extensions #

You’ve got two straightforward options here:

• Via Command Palette: Open the command palette (Ctrl+Shift+P on Windows/Linux, Cmd+Shift+P on Mac), type Extensions: Uninstall All Installed Extensions, and select the option. This wipes every extension in one click.
• Manual Folder Deletion: If the command palette method doesn’t work, delete the extensions folder directly:
  • Windows: %USERPROFILE%\.vscode\extensions
  • Mac: ~/.vscode/extensions
  • Linux: ~/.vscode/extensions

Step 2: Reset VS Code to Default Settings #

To fully wipe all customizations (settings, keybindings, workspace configs, etc.), use one of these methods:

• Quick Reset via Command Palette: Open the command palette, type Preferences: Reset Settings, and confirm. This reverts your user settings to their out-of-the-box state.
• Full Manual Reset (for deeper issues): If you want a complete clean slate, delete these folders:
  • Windows:
    • Settings: %APPDATA%\Code\User
    • Cache: %APPDATA%\Code\Cache
    • Local Storage: %APPDATA%\Code\Local Storage
  • Mac:
    • Settings: ~/Library/Application Support/Code/User
    • Cache: ~/Library/Caches/Code
    • Local Storage: ~/Library/Application Support/Code/Local Storage
  • Linux:
    • Settings: ~/.config/Code/User
    • Cache: ~/.cache/Code
    • Local Storage: ~/.config/Code/Local Storage

Quick Tips Before You Start #

• Backup First: If you have custom settings or favorite extensions you want to restore later, export your settings via Preferences: Export Settings in the command palette, and jot down the extensions you need.
• Restart After: Close and reopen VS Code once you’re done—this ensures all changes take effect.
• Test Gradually: After resetting, install extensions one at a time (starting with your essential HTML tools) to pinpoint which one caused the markup issue. That way you won’t run into the same problem again.
