nodemon 1.10.1 does not restart when source code file changes

[xiedwill]

I install the latest nodemon (1.10.1) on Ubuntu 16.04, with node v6.4.0

npm install -g nodemon

then I run

nodemon server.js

and changes server.js, the server would not restart automatically. However, when I install an earlier version, and do the same thing, the server will restart correctly.

npm install -g [email protected]

Looks like a bug with the new update. I reverted back to 1.10.0 for the time being!

[geooogle]

Same here

[remy]

@xiedwill @EngineeredTruth what OS are you running on? So I can check on my side to debug?

[xiedwill]

@remy Ubuntu 16.04.1 LTS

[seamoss]

:+1:

Downgraded to 1.10.0, issue goes away.

Mac OSX 10.11.5
Node.js 6.4.0
NPM 3.10.3

[remy]

Anyone using Docker here? Or is this directly on the command line?

[seamoss]

Command line, here.

[xiedwill]

Command Line directly.

On Mac OSX had the same problem with 1.10.1 (the revert/rollback isn't active yet, or npm still has 1.10.1 cached for now).

Also crashed on restarting manually from the command line

@fdoxyz

npm rm nodemon -g
npm i [email protected] -g

[fdoxyz]

@seamoss yep, sorry didn't notice your comment while typing mine :)

[remy]

I posted a moment ago, but deleted the comment. It's happening on node@4 too.

I'm replicating with the rs command. I need to check what's going on with nodemon not restarting when the source changes.

[bdanmo]

Had the same issue; reverted and fixed. Change file would not restart, and when I tried rs command manually, stdin would be null, and the restart would fail.

[remy]

Latest version, 1.10.2 has the fix. Sorry for the disruption folks.

[seamoss]

:+1: awesome!

[tomasdev]

@remy I'm experiencing this issue on a Docker image running nodemon, was it a known issue? I'm just going thru all open issues related to Docker in the meantime.

[vitorpiovezam]

Thanks, this works great @seamoss .

npm rm nodemon -g && npm i [email protected] -g

[remy]

@vitorpiovezam I'd recommend installing the latest version (1.14.x), there's been a lot of work since 1.10.0 so you might find a problem is fixed but also you can report new issues and they'll be investigated too.

[modikrunal202]

@remy Updated to 1.14.10 and I can't get the server restarted on file changes.

I'm changing and saving app.js and other js files in subfolders and nothing happens (server is not restarting).

@xiedwill @EngineeredTruth what OS are you running on? So I can check on my side to debug?

Seems this could be a *chokidar *issue.  Others are working on that.

I was puzzled why the issue was closed since Windows 10 isn't working.

Hello @remy Sir,
I am facing problem in nodemon, it works well when I don't work with server. But when I work with server, nodemon does not work. It is not able to start my "js" file.

When I save my code, it only shows-
[nodemon] restarting due to changes...
[nodemon] restarting due to changes...

But not starting my "js" file again. Tell me where I am going wrong.
Please help me out or provide me a solution for it!

Operating System- Windows 10
nodemon version- 1.18.11
express version- 4.16.4
nodejs version- 11.10.1

[Charlotte000]

@sumiie24 , I had the same problem. My solution was adding C:\Windows\System32\ to the system variable in the PATH.

[khemchand123]

i install properly nodemon and show restart any changes
but in localhost not show any change which i update

cmd show->
D:\node.js\express-node-module>nodemon server.js

Amazing Thanks A Lot

[ridbay]

This works for me;

Delete these directories; C:/Users/{user}/AppData/Roaming/npm and C:/Users/{user}/AppData/Roaming/npm-cache and re-installed global npm modules.

Sheers!!
