How to solve this after running npm to compile?

I believe I ran through these steps and fixed that error. I stopped at the point of checking the version of node.

I will add - while this improved the pinched audio I was hearing on VHF-FM, I still do not like what I'm hearing as compared to the same SDR (in my case an RSP1a) and SDR Console.

Followed all the steps - Success!
After recompile, FM mode is much better now!
Thanks!
I landed on Bas' SDR today and found some stations using FM on 11 meters and that FM sounded great. So why does VHF/UHF FM sound so pinched up and also have so much hissing involved?

I don't know if BAS has made the modification you've recommended, but in my case, FM stations on 11 meters sound really better.
I did not modify the FM-code.
Beware, that Soapy isn't as good as the RX888MK2 direct sampling-injection.
Soapy does have some strange things AND does convert if needed.
When you are able to avoid Soapy, you better do so.
When it comes to the RSP1A and older devices, you can pick between the 2.13 and 3.xx API, I really suggest you use the 2.13 API and use the 2.13 plugin, it's far better. Also more stable.
