【问题描述】：

我尝试使用 docker 设置 run rails 项目，所以我构建了一个 dockerfile，如下所示

FROM ruby:2.6.6

RUN apt-get update -qq && apt-get install -y build-essential

# for mysql
RUN apt-get install -y default-libmysqlclient-dev

RUN apt-get install -y git-core zlib1g-dev libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev nodejs yarn

RUN gem install bundler

ENV APP_HOME /myapp
RUN mkdir $APP_HOME
WORKDIR $APP_HOME

ADD Gemfile* $APP_HOME/
RUN bundle install

ADD . $APP_HOME

当我运行docker build . 时，它总是出现如下错误：

 => ERROR [10/11] RUN bundle install                                                                                                                                                                                  1.0s

所以请帮帮我。

【问题讨论】：

您的主机不是x86，这与您的 CPU 架构不匹配。我假设你在 Apple M1 上构建它
不，我不使用 Apple M1，我看到的问题是我为 nokogiri gem 安装了libxslt-dev liblzma-dev patch

标签： ruby-on-rails ruby docker nokogiri

【解决方案1】：

我刚刚更改了我的 Dockerfile，它对我有用

FROM ruby:2.6.6

RUN apt-get update -qq && apt-get install -y build-essential
# for mysql
RUN apt-get install -y default-libmysqlclient-dev

RUN apt-get install -y libxslt-dev liblzma-dev patch git-core zlib1g-dev libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev nodejs yarn

RUN gem install bundler
RUN gem install nokogiri --platform=ruby

ENV APP_HOME /myapp
RUN mkdir $APP_HOME
WORKDIR $APP_HOME

ADD docker_app/Gemfile* $APP_HOME/
# RUN bundle config build.nokogiri --use-system-libraries
RUN bundle install

ADD docker_app/. $APP_HOME
