Compile locally for production?

Hi I need to know how would I compile locally for production rather than at server, as my server resources can not afford the compilation process. I was looking at this issue at webpacker

I tried : bundle exec rails webpacker:compile , I got error:

Error: Command 'webpacker:compile' not recognized

but I am already have gem 'webpacker' in my Gemfile and its installed…

Can you please tell me how did you compile locally? I just need to locally compile the react project, not the whole assets.

[hopewise]

Okey, here is my deployment log:

Webpacker is installed 🎉 🍰
Using /var/www/myapp/releases/20190314152431/config/webpacker.yml file for setting up webpack paths
Compiling…
Compilation failed:

so, it seems that it does compile however, here is my 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

  extensions:
    - .jsx
    - .js
    - .sass
    - .scss
    - .css
    - .module.sass
    - .module.scss
    - .module.css
    - .png
    - .svg
    - .gif
    - .jpeg
    - .jpg

development:
  <<: *default
  compile: false

  # Reference: https://webpack.js.org/configuration/dev-server/
  dev_server:
    https: false
    host: localhost
    port: 3035
    public: localhost:3035
    hmr: false
    # 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': '*'
    watch_options:
      ignored: /node_modules/


test:
  <<: *default
  compile: false

  # Compile test packs to a separate directory
  public_output_path: packs-test

production:
  <<: *default

  # Production depends on precompilation of packs prior to booting for performance.
  compile: false

  # Cache manifest.json for performance
  cache_manifest: true

Any idea?

[hopewise]

I deploy via Capistrano… I will set compile: false to save server power…
