Failed at the [email protected] postinstall script

Question

I was trying to install electron into my project, but it is giving an error. I also tried to do this with unsafe-perm, but still giving the same error.

npm install electron --save-dev --save-exact

Can you please try(after removing node_modules)

sudo npm install electron --save-dev --save-exact --unsafe-perm=true --allow-root

I was running into the same error and this is what worked for me.
