Resolve ‘cp’ Command Error in Syncfusion React PDF Viewer

14 Jul 20261 minute to read

The Unix cp command is not available in the Windows Command Prompt. Use one of the following Windows-native alternatives to copy the required ej2-pdfviewer-lib assets into a public or source folder used by the application.

CMD (xcopy) — recursive directory copy

xcopy /s /e /i .\node_modules\@syncfusion\ej2-pdfviewer\dist\ej2-pdfviewer-lib public\ej2-pdfviewer-lib

PowerShell (Copy-Item) — recursive directory copy

Copy-Item .\node_modules\@syncfusion\ej2-pdfviewer\dist\ej2-pdfviewer-lib -Destination .\src\ej2-pdfviewer-lib -Recurse -Force

Notes:

  • Run the command from the project root so the node_modules path resolves correctly.
  • Windows paths use backslashes (). Adjust paths if your project structure differs.
  • Ensure sufficient permissions to write to the destination folder.

For cross-platform scripts in package.json, consider tools such as shx or copyfiles to avoid OS-specific commands.
