Question

使用docker尝试构建映像，但是由于nokogiri gem问题，我在捆绑时收到上述错误

我的Docker文件是

RUN apt update
RUN apt install -y ruby
RUN gem install bundler
RUN cd /usr/src/app
WORKDIR /web
ADD Gemfile /web/
RUN bundle

但是，当我RUN bundle结尾时，^出现以下错误：

Answer 1

将以下行添加到Dockerfile中，它将处理依赖项

RUN apt install -y build-essential patch ruby-dev zlib1g-dev liblzma-dev

在RUN bundle命令之前

然后再次运行构建

docker build -t dock .

对于高山

RUN set -x \   && apk upgrade --no-cache \    && apk add --no-cache
--virtual build-dependencies \
    build-base \   && apk add --no-cache \
    libxml2-dev \
    libxslt-dev \   && gem install nokogiri \
    -- --use-system-libraries \
    --with-xml2-config=/usr/bin/xml2-config \
    --with-xslt-config=/usr/bin/xslt-config \   && apk del build-dependencies

Docker-ruby，nokogiri-安装nokogiri（1.10.2）时发生错误，
