Javascript 运行新Rails应用程序的服务器时出现Webpacker错误

刚刚创建了一个全新的Rails应用程序，在运行服务器时收到此错误：

Webpacker can't find application.js in /public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{
}

这是我的

webpacker.yml

：

# Note: You must restart bin/webpack-dev-server for changes to take effect

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

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

development:
  <<: *default
  compile: true

  # 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: true

  # 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

我没有

manifest.json

-这不是应该自动创建的吗

有什么想法吗？

问题来自本地计算机上node的版本。当您创建rails应用程序时，可能出现了如下弹出窗口所示的错误：

JavaScript应用程序源目录已存在
apply/Users/mconiaris/.rbenv/versions/2.6.4/lib/ruby/gems/2.6.0/gems/webpacker-4.0.7/lib/install/binstubs.rb
复制桶
生存箱
创建bin/webpack
创建bin/webpack开发服务器
append.gitignore
安装所有JavaScript依赖项[4.0.7]
运行纱线添加@rails/webpacker from“
纱线添加v1.17.3
信息找不到锁文件。
[1/4]尝试rake webpacker：不幸的是，仍然会出现相同的错误！尝试bundle exec bin/webpack dev server请发布您的
配置/webpack.yml
文件以及运行
/bin/webpack的输出。
@rossta我编辑了我的帖子，包括
webpack.yml
和
/bin/webpack
