Thanks for reporting this issue. However we'd need some more information to look into this.

Can you install nodemon via npm i nodemon and in terminal run node_modules/.bin/nodemon --verbose

Thanks

HazizKhan · 2018-12-03T08:32:23Z

@alan-agius4 Thanks for replying
after installing node-watch there is no such file called node-watch in node_modules/.bin

alan-agius4 · 2018-12-03T20:00:47Z

@HazizKhan, I updated my above comment.

vovikdrg · 2018-12-04T05:17:20Z

Looks the same as my problem #13125

vovikdrg · 2018-12-04T05:29:14Z

@alan-agius4

I did run ng serve
then npm i nodemon
then in separate cmd node_modules/.bin/nodemon --verbose

As a result it still recompiles in ng serve

while in that window where i did run nodemon I have output. But while ng serve is recompiling nodemon is not printing anything new. I hope it make sense..

@HazizKhan do you have dist folder in your project? We do have server compiled in that folder.

alan-agius4 · 2018-12-04T10:40:13Z

@vovikdrg are you including the dist folder in the typescript compilation by any chance ie, adding it in the tsconfig.json?

It would be great if you can you setup a minimal repro please?

You can read here why this is needed. A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.

This might be related to your directory structure so its really important to get an accurate repro to diagnose this.

vovikdrg · 2018-12-04T23:56:52Z

@alan-agius4 Give me some time. I need to ask permission.

Also its probably does not make sense to create new. I am thinking to leave same structure but remove all project related stuff. It seems to bug in structure or specifically in way we created it.

vovikdrg · 2018-12-04T23:57:37Z

@alan-agius4 It won't be before Monday for sure.

HannesT117 · 2019-01-03T10:10:47Z

Any updates on this? I have a similar problem. For some reason, when removing assets from root path in angular.json, it stopped recompiling. I was not able to reproduce this in a demo app, though. In any other projects, this wasn't a problem at all. Perhaps someone has a clue what's happening, so I'm sharing it anyways.

"projects": {
  "myProject": {
    "root": "",
     "sourceRoot": "src",
     "assets": [
        <!-- removed this -->
        {
          "glob": "README.md",
          "input": "",
          "output": "/assets"
        }
        <!-- until here -->
      ]
   }
}

alan-agius4 · 2019-01-03T11:02:40Z

My though would be something related to webpack-contrib/copy-webpack-plugin#296

Can you check which version of copy-webpack-plugin you have installed. (npm ls copy-webpack-plugin)?

it should be version 4.5.4 or later.

HannesT117 · 2019-01-03T12:58:42Z

Awesome! It was v4.5.3. After updating @angular-devkit/build-angular to the current version, my problem was gone. Thanks a lot!
@vovikdrg, do you think this could help you as well?

alan-agius4 · 2019-01-03T14:50:56Z

This issue is now obsolete due to changes in the recent releases. Please update to the most recent Angular CLI version.

If the problem persists after upgrading, please open a new issue, provide a simple repository reproducing the problem, and describe the difference between the expected and current behavior.

tony2tones · 2019-04-03T07:40:17Z

To resolve this issue i did the following:

ng update @angular/cli @angular/core

problem still exists with angular 7.2.15 and angular-cli 7.3.0

OussamaHan · 2019-05-30T14:31:54Z

I had this problem as well. I suggest that you re-install copy-webpack-plugin. This is what fixed it for me.
npm install copy-webpack-plugin --save-dev

falasvand · 2019-05-31T15:15:44Z

project im working on doesnt use webpack
