What are common errors when running the CLI on Windows?

Answer

Common issues: 'node' is not recognized (Node.js not in PATH — restart terminal or reinstall). Execution policy errors in PowerShell (run Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned). Long path errors (enable long paths: registry key HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled=1). Permission denied on node_modules (run terminal as Administrator or fix folder permissions).
