1. Remove the Corepack Shims (Uninstalls Corepack-managed pnpm)

Corepack works by creating shim binaries for package managers.Running the disable command removes these shims (including pnpm and yarn):

corepack disable

2. Delete Corepack’s Cache & Downloaded Binaries

Corepack stores downloaded package manager binaries in a global cache directory. Delete this folder to completely clean up downloaded pnpm versions:

• macOS / Linux:
  rm -rf ~/.cache/node/corepack # Or if using XDG defaults: rm -rf ~/.local/share/corepack
• Windows (Command Prompt):
  rmdir /s /q "%LOCALAPPDATA%\node\corepack"
• Windows (PowerShell):
  Remove-Item -Recurse -Force "$env:LOCALAPPDATA\node\corepack"

3. Uninstall Corepack Itself

Depending on how Corepack was installed on your machine:

• If installed manually via npm:
  npm uninstall -g corepack
• If installed via Homebrew (macOS):
  brew uninstall corepack
• If included with Node.js (.msi installer on Windows or pre-packaged binary):
  Corepack comes bundled with Node.js by default. Running corepack disable (Step 1) is sufficient to remove its executable shims from your PATH. If you want to strip it entirely from a Windows Node.js installation, run the Node.js .msi installer, choose Modify, and uncheck the Corepack manager feature.

4. Verify Cleanup

Check that neither command is available in your shell:

corepack --version
pnpm --version

Both commands should return command not found (or equivalent).
