ruby-on-rails - 在 rails 6 和 docker 中找不到命令“webpack-dev-server”

问题描述

我有一个 Rails 6 应用程序。我只是做了 rails new 来生成它，没有别的。

这是我的码头文件：

ARG RUBY_VERSION
# See explanation below
FROM ruby:$RUBY_VERSION

ARG PG_MAJOR
ARG NODE_MAJOR
ARG BUNDLER_VERSION
ARG YARN_VERSION

# Add PostgreSQL to sources list
RUN curl -sSL https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add - \
  && echo 'deb http://apt.postgresql.org/pub/repos/apt/ stretch-pgdg main' $PG_MAJOR > /etc/apt/sources.list.d/pgdg.list

# Add NodeJS to sources list

# Install dependencies
# We use an external Aptfile for that, stay tuned
COPY ./dockerDev/Aptfile /tmp/Aptfile
RUN apt-get update -qq && DEBIAN_FRONTEND=noninteractive apt-get -yq dist-upgrade && \

    $(cat /tmp/Aptfile | xargs) && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* && \
    truncate -s 0 /var/log/*log

# Configure bundler and PATH

ENV PATH /app/bin:$BUNDLE_BIN:$PATH

# Upgrade RubyGems and install required Bundler version
RUN gem update --system && \
    gem install bundler:$BUNDLER_VERSION

# Create a directory for the app code
RUN mkdir -p /app

WORKDIR /app
COPY Gemfile /app/Gemfile
COPY Gemfile.lock /app/Gemfile.lock
RUN bundle install
COPY . /app
# RUN rails webpacker:install

# Add a script to be executed every time the container starts. Fixes a Rails-specific issue that prevents the server from restarting when a certain server.pid file pre-exists
# COPY entrypoint.sh /usr/bin/
# RUN chmod +x /usr/bin/entrypoint.sh
# ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000

这是我的 docker-compose 文件：

version: '3.5'

services:
  app: &app
    build:
      context: .
      dockerfile: ./Dockerfile
      args:

  webpacker:
    <<: *app
    command: ["/bin/bash","-c", "./bin/webpack-dev-server"]
    ports:
      - '3035:3035'
    volumes:
      - .:/app:cached
      - bundle:/bundle
      - node_modules:/app/node_modules
      - packs:/app/public/packs
    environment:
      - NODE_ENV=${NODE_ENV:-development}
      - RAILS_ENV=${RAILS_ENV:-development}
      - WEBPACKER_DEV_SERVER_HOST=0.0.0.0

volumes:
  postgres-data:
  # redis:
  bundle:
  node_modules:
  rails_cache:
  packs:

在另一台计算机上，我运行了 rails webpacker:install，所以我在bin文件夹中有以下文件：

#!/usr/bin/env ruby

ENV["RAILS_ENV"] ||= ENV["RACK_ENV"] || "development"
ENV["NODE_ENV"]  ||= "development"

require "pathname"
ENV["BUNDLE_GEMFILE"] ||= File.expand_path("../../Gemfile",
  Pathname.new(__FILE__).realpath)

require "rubygems"
require "bundler/setup"

require "webpacker"
require "webpacker/dev_server_runner"

APP_ROOT = File.expand_path("..", __dir__)
Dir.chdir(APP_ROOT) do
  Webpacker::DevServerRunner.run(ARGV)
end

此设置适用于执行 webpacker:install 的笔记本电脑，但在任何新笔记本电脑上都会生成以下错误：

webpacker_1  | yarn run v1.13.0
webpacker_1  | error Command "webpack-dev-server" not found.
webpacker_1  | info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

知道为什么吗？由于文件显然在那个文件夹中？

大卫更新：

rails  rake  setup  webpack  webpack-dev-server  yarn
