Solution to npm install "npm ERR! Error: EPERM: operation not permitted" error

I was trying to install pngquant imagemin plugin using this command:

  
npm install imagemin-pngquant
  

... in Minimalist GNU for Windows running in Windows 10 64-bit OS. And I got this errors:

I have tried to run the Minimalist GNU as Administrator but after several retries I still getting those errors. The errors gone after I disabled my anti-virus (Avast):

If you're still getting those errors after disabling your anti-virus for first run, try it to run for several times until you get it to install successfully.
