what I need is to write output of running command in file.

Same problem here. I tried it with Gulp 4.0.2 and I got this. Went down to Gulp 3.9.1 and it works. So it seems there's been a breaking change somewhere in Gulp or Vinyl.

No updates to fix this one up? We cannot stay to gulp 3.9.1 forever
