Webpacker: Webpacker not listen for files to compile automatically

[niusmake]

Excuse me,
I used docker to build my Rails + Vue + Webpacker.
When I docker-compose up, it is very beautiful to build a good environment with Compiled successfully.

But when I go to modify the file, webpacker does not automatically compile the file.

And in my /public/packs/, there is no compiled file, but the application reads the file.

Is this what is the reason?

please help me

use webpacker (4.0.7)

use webpack-dev-server (3.7.2)

# /config/webpacker.yml


default: &default
  source_path: app/javascript
  source_entry_path: packs
  public_output_path: packs
  cache_path: tmp/cache/webpacker

  # Additional paths webpack should lookup modules
  # ['app/assets', 'engine/foo/app/assets']
  resolved_paths: []

  # Reload manifest.json on all requests so we reload latest compiled packs
  cache_manifest: false

  # Extract and emit a css file
  extract_css: false

here's mine

  dev_server:
    https: false
    host: 0.0.0.0
    port: 3035
    public: 10.10.10.12:3035
    hmr: true
    # Inline should be set to true if using HMR
    inline: true
    overlay: true
    compress: true
    disable_host_check: true
    use_local_ip: false
    quiet: false
    headers:
      'Access-Control-Allow-Origin': '*'

@niusmake
Excuse me, can you tell me how to solve the problem? i meet the same one.

Hello
When my solution was very weird, when executing a project docker under a special file name, webpacker not listen for files to compile automatically.
But when I moved to a folder with another file name, he executed it normally.
Hope my solution for your reference.
