eig*_*h14 6 ruby ruby-on-rails docker docker-compose
我正在尝试容器化我的 Rails 应用程序并通过 docker-compose 启动它。该应用程序构建良好docker-compose build，但在尝试启动时失败：
$ docker-compose up

puma | /usr/local/bundle/gems/bootsnap-1.10.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:15:in `require': cannot load such file -- nokogiri (LoadError)
我特别为最后一行而苦苦挣扎：
1.10.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:15:in `require': cannot load such file -- nokogiri (LoadError)
我的 Dockerfile 如下：
# syntax=docker/dockerfile:1
FROM ruby:3.0.4
RUN apt-get update && apt-get install -y nodejs postgresql-client zlib1g-dev liblzma-dev patch
RUN gem install nokogiri --platform=ruby
WORKDIR /myapp
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle install
# Add a script to be executed every time the container starts.
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000
# Configure the main process to run when running the image
CMD ["rails", "server", "-b", "0.0.0.0"]
我尝试遵循此处的建议，注意到 Docker 正在使用 Debian 构建其映像。但是，这似乎不起作用。
我也遇到过这篇文章，但在这种情况下，我不是使用 Alpine Linux 进行构建，而是使用ruby似乎在 Debian 上运行的默认映像。另外，我还尝试在我的 M1 macOS (11.3.1) 计算机上启动。
这里有什么建议或提示吗？我对通过 Docker 构建 Rails 应用程序还比较陌生，如果有任何提示，我将不胜感激。
最后，分别是我的Gemfile和Gemfile.lock文件：
