webpack-dev-server 不会在 Docker Compose 中 运行

Question

当运行 docker-compose up时，我得到以下错误：

webpacker_1 | yarn run v1.22.5 webpacker_1 | info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command. webpacker_1 | error Command "webpack" not found. neilsite_webpacker_1 exited with code 1

我的 Dockerfile 是：

FROM ruby:2.6.5

RUN apt-get update && apt-get install -y build-essential libpq-dev

RUN curl -sL https://deb.nodesource.com/setup_14.x | bash \
&& apt-get update && apt-get install -y nodejs && rm -rf /var/lib/apt/lists/* \
&& curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - \
&& echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list \
&& apt-get update && apt-get install -y yarn && rm -rf /var/lib/apt/lists/*

ENV RAILS_ROOT /app
ENV PORT 3000

RUN mkdir $RAILS_ROOT
WORKDIR $RAILS_ROOT

COPY Gemfile $RAILS_ROOT
COPY Gemfile.lock $RAILS_ROOT
RUN bundle config --global frozen 1
RUN bundle install --without development test

COPY package.json $RAILS_ROOT
COPY yarn.lock $RAILS_ROOT
RUN yarn install --check-files --frozen-lockfile

我的 docker 撰写文件是：

为什么找不到 webpack？

Answer 1

我设法解决了这个问题。

问题是我没有在我的 webpacker 服务上为 bundle 和 yarn 配置相同的卷，因为我在我的网络服务上。
