Yeah If you install the latest version of node then it will clearly work. As Realm uses latest version of node. Go for this link to download node : https://nodejs.org/en/download/

[phoenixit99]

download: newest version node : https://nodejs.org/en/download/ After that install: sudo npm install realm --allow-root=true --unsafe-perm=true
