【问题描述】：
我知道最近的 mimemagic 问题，我设法通过捆绑更新到 0.3.7 解决了我的一个 Rails 项目 - 但由于某种原因，我无法在下面的项目中解决它。
我有一个 Rails 6 项目，我在一台新笔记本电脑上第一次设置。我的笔记本电脑没有正确的 Ruby 设置，所以我在我的项目中添加了一个 Dockerfile，如下所示：-
Dockerfile
FROM ruby:2.7
RUN apt-get update -qq && apt-get install -y nodejs postgresql-client
WORKDIR /radius
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle update mimemagic
RUN bundle install
COPY . /myapp
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000
CMD ["rails", "server", "-b", "0.0.0.0"]

gem 'sidekiq', '~> 5.2', '>= 5.2.5'
gem 'sitemap_generator', '~> 6.0', '>= 6.0.1'
gem 'underscore-rails'
gem 'whenever', require: false
然后我尝试：-
docker-compose build
docker-compose up
连同以下的每一种组合：-
- 在我的 dockerfile 中使用
bundle update mimemagic - 使用
gem 'mimemagic', '~> 0.3.7'专门将 gem 添加到我的 Gemfile - 手动将我的 Gemfile.lock mimemagic 版本从
0.3.5更改为0.3.7 - 将
RUN apt-get install shared-mime-info添加到我的 Dockefile 中
我只是得到以下之一：-
Could not find mimemagic-0.3.x in any of the sources
web_1 | Bundler::GemNotFound: You have requested:
web_1 | mimemagic ~> 0.3.7
web_1 |
web_1 | The bundle currently has mimemagic locked at 0.3.5.
web_1 | Try running `bundle update mimemagic`
我还尝试将导轨撞到 6.0.3.6 并再次运行 docker 构建，这给了我主动支持问题：-
web_1 | Bundler::VersionConflict: Bundler could not find compatible versions for gem "activesupport":
web_1 | In snapshot (Gemfile.lock):
web_1 | activesupport (= 6.0.3.5)
web_1 |
web_1 | In Gemfile:
web_1 | rails (~> 6.0.3.6) was resolved to 6.0.3.6, which depends on
web_1 | activesupport (= 6.0.3.6)
web_1 |
web_1 | dotenv-rails was resolved to 2.7.6, which depends on
web_1 | railties (>= 3.2) was resolved to 6.0.3.5, which depends on
web_1 | activesupport (= 6.0.3.5)
web_1 |
web_1 | Running `bundle update` will rebuild your snapshot from scratch, using only
web_1 | the gems in your Gemfile, which may resolve the conflict.
我需要做什么才能安装这个 gem？
【问题讨论】：
-
可能是那个版本的 rails 锁定了 mimemagic。检查您的 Gemfile.lock。使用最新版本。如果它是一个新项目，则没有理由使用旧版本，也没有发布候选版本。
gem 'rails', '~> 6.1'。您应该在部署之前进行捆绑更新。 -
这不是一个全新的项目——很新。不过，这是第一次在这台笔记本电脑上进行设置。我尝试将它撞到 rails 6.0.3.6，它给了我帖子中提到的 activesupport 错误。
-
@Schwern 在部署之前进行捆绑更新是什么意思？我不会在任何地方部署这个项目。
-
您正在 Docker 上部署/安装它。 Gemfile.lock 的重点是锁定 gem 的版本以获得一致的安装。
bundle update就在bundle install失败之前。它也很慢，你不需要在 Docker 中捆绑更新，你可以在任何地方进行。无论如何，您的 Gemfile 中的 else 是什么？ dotenv-rails 不是 rails 依赖项。 -
@Schwern 其他一些东西 - 将它们添加到帖子中。尽管如此，Rails 的 activesupport 依赖仍然存在问题，无论 dot-env 是什么。
