Nodemon: process.stdin.setRawMode is undefined when running in nodemon

[toddbu]

I have an app that runs perfectly under node but fails under nodemon. The problem is that process.stdin.setRawMode is set to undefined when running nodemon. Here's a test script (x.js)...

console.log(process.stdout.isTTY)
console.log(process.stdin.setRawMode)

When I run node x.js, I get...

[Function]

When I run ./node_modules/.bin/nodemon x.js, I get...

undefined

Not that it should make a difference, but I'm running this on a Raspberry Pi (ARM) with the most recent version of Raspbian

Here's the dump...

Have you tried with the --no-stdin flag set? Equally, you can try with --spawn flag too.

The --no-stdin seems to work. I didn't see that option when I did --help. Thanks for the pointer
