I followed a blog titled Creating an Electron Application for the Raspberry Pi, regarding starting an Electron app in Raspberry Pi using the Buster OS and got it to compile.
But when it came to building the application, using the electron-builder, I keep getting the error of cannot execute... after running the command electron-builder --dir --armv7l --linux deb and can't figure what the issue is. I've attached the error 
Sorry to be 6 months late to the party, but I also just tried to create an Electron app to run on the Raspberry Pi.
It turns out that while Electron runs fine on Arm processors, there are a bunch of problems with building an Electron app via electron-builder on an Arm processor.
The error that you are seeing is just the opening of the rabbit-hole.
Most of the issues appear to be due to electron-builder having apparently been implemented on an x86 machine, with no real care having been taken to make sure that it works on any other architecture - x86 is just pretty-much assumed.
So, for me, the answer was to build the Arm target on an x86 Linux machine, using exactly the same command-line that you used.
So far, I have found that I can build for OS X and Windows on OS X, for Linux x86, Linux Arm, OS X, and Windows on Linux x86. I don't have Windows machine, so I'm not sure what actually works there.
Code signing is yet another rabbit hole....
