i followed this solution but still i am getting same error.

my node version is 8.4.0

Can you tell me how can i solve this error.?

Answer 1

Your dependency zetta is including an ancient version of spdy which is not compatible with you current version of Node. There is currently an open issue on zetta's github about this, which has a work around:

process.EventEmitter = require('events').EventEmitter
const zetta = require('zetta')

Your mileage may vary on that hack, I have not tested it myself. Alternatively, you could wait for the zetta team to fix their dependency or downgrade your node installation.
