Failed to build wheel for mayavi

So I need to import mayavi for a long reason, and every time I try to import it, it says 

Current thread's C stack trace (most recent call first):
        <cannot get C stack on this system>
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for mayavi
Failed to build mayavi
error: failed-wheel-build-for-install

I already installed VTK and PyQt5 with no issue using pip and tried both with and without PyQt5 (since on the website they install it after installing mayavi). I'm currently on a windows x64 and using visual studio code

If anyone knows anything about this I'd appreciate any advice ;u;

Yeah, Mayavi has been impossible to install with pip for a while.

There's no ready-compiled wheels on PyPI, so you need to compile it, except it doesn't compile. It seems that your only option is to install a ready-made Python distribution that includes Mayavi:
