truffle compile , Error: Error: Cannot find module 'websocket'

[sowmyakannan]

I upgraded Truffle, then did a new install for truffle-hdwallet-provider using the following command:

$ npm install truffle-hdwallet-provider.

Now when I run truffle compile i get an error saying this:

Error: Cannot find module 'websocket'

Any inputs on how to fix this would be appreciated.

I have this problem too (with truffle test). Does anyone have a solution ?
