@jonathan-marz 's solution quoted here :

Try to add --unsafe-perm=true --allow-root to the end and for me it worked.

worked for me and allowed me to run cypress as a dev dependency using :

sudo npm i --save-dev cypress --unsafe-perm=true --allow-root

I was facing the same issue with: npm 6.13.4 ubuntu 18.04 node 12.14.0

Found another issue on google with the solution. Try to add --unsafe-perm=true --allow-root to the end and for me it worked. But first it looks like it worked but at the end it fails.

Good damn this sucks. 😦
