PdfMake | Error: ENOENT: no such file or directory, open './build/vfs_fonts.js'

I'm using the PDFMake library and trying to use a custom font in its output. This font is made for the Persian language. I followed the steps described on the web page below custom-fonts-client-side/vfs

I encountered the following error when executing the node build-vfs.js "./examples/fonts" command:

Internal/modules/cjs/loader.js:888
  throw err;
  ^

Error: Cannot find module 'D:\ProgrammingWorld\Github_Library\Cyeng\NewProject\onGit\NewProject\build-vfs.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:885:15)
    at Function.Module._load (internal/modules/cjs/loader.js:730:27)

    at internal/main/run_main_module.js:17:47 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

So I decided to change the command and write it as follows:

node node_modules/pdfmake/build-vfs.js "node_modules\pdfmake\examples\fonts"

But unfortunately, I got a new error:

Go to node_modules/pdfmake/ directory and run node build-vfs.js "./examples/fonts"
