This worked for me to install electron. However I got a 404 on xtract-zip:

npm ERR! 404  'xtract-zip' is not in the npm registry.

I instead did:

npm install extract-zip@1.6.0

Also, I noticed I was getting errors for writing to the node_modules directories, so I used chown on them:

sudo chown -R $(whoami) ~/.npm
sudo chown -R $USER /usr/lib/node_modules

Not sure if they all were needed, but I wanted to document all of my steps to hopefully help.

I am having the same problem. Wiped the pi and reflashed the image from scratch. Spent a few hours myself tonight trying various things to fix it without getting anywhere. Same exact errors as pasted above.
