There is a problem with nodemon

I developed a project on top of this, and a few months ago I started having this problem. For a while I though it was a bug on my end, but after downloading a fresh clone of this project it seems I can replicate the bug. Here is the output of running docker-compose up on the first example, 01-express-nodemon:

I'm still seeing this issue

I am also seeing odd nodemon errors when attempting to run the 01-express-nodemon example in a clean install. I've glanced over the chevdor proposals, and yes that makes the nodemon errors disappear, by not running nodemon at all. Not really a fix (and profuse apologies if I have that wrong, I'm learning this stuff too...)

My error messages:

Update: I'm continuing to play with this, and totally got it running correctly with a single line of code change. In the file docker-compose-nodejs-examples/01-express-nodemon/Dockerfile simply change the first line of code:
FROM node:0.10.38
to a more modern docker image . I chose
FROM node:9.2.0

When I did that WITHOUT any other changes within the 01-express-nodemon repository, the code ran without errors. Note there are other warnings, e.g. jade --> pug, but that can all be fixed. After the install, I change one line of code (let's use myApp --> routes/index.js... change title: Express to title: Express wow, now with Nodemon Restarts!) When I save the file, I see and immediate server restart. A simple refresh in the browser shows the change. This does not refresh the browser/client automatically.

We have modernized this project, please check if the issue still persists in the new version and re-open if necessary. Thanks for your contribution! :)
