I tried this commit and found it worked. Can @slashdotdash merge it in? https://github.com/ioddly/node-ledger-rest/commit/7dab33c0be0cb888c9cfbe72821d52f194c5af0a

Helps me to upgrade node-ledger-rest to node 7.

@Sunillabs108 npm install restify@4.3.0 --save fixes the issue.

[krishnapsarthi]

I am also getting same error on node v8.8.1 running statsd.

util.js:971
throw new TypeError('The super constructor to "inherits" must not ' +
^

TypeError: The super constructor to "inherits" must not be null or undefined

Any solution on this?

[wactbprot]

Same here at:

util.js:971
    throw new TypeError('The super constructor to "inherits" must not ' +

Thank you!

@wactbprot I have the exact same error as you (down to util.js:971:11), but I don't even use this package, nor do I use spdy. I found this issue just by googling the error message, but I think the problem arises from readable-stream, see https://github.com/nodejs/readable-stream/blob/f81f716335c7c5f500618c7ee8fd29e08b1cf2b5/lib/_stream_duplex.js#L53

I'm experiencing this problem when I'm using Rollup to bundle my application. There is an old issue with a bit of discussion about the cause: nodejs/readable-stream#237

What solved the problem for me personally was using rollup-plugin-node-builtins

Hopefully this helps someone somewhere :)
