"listen" 使用 Docker 安装 Jekyll 时发生冲突

Question

我正在尝试在 Dockerfile 扩展 Jenkins 官方镜像 (2.19.1)

中安装 Jekyll

以下命令：

RUN apt-get install -y ruby-full rubygems
RUN gem install jekyll

产生以下错误：

Step 2 : RUN gem install jekyll

有没有人遇到同样的错误？怎么修？谢谢。

Answer 1

错误是由于 a bad ruby version for listen :

IMPORTANT: Ruby 2.1 is officially outdated and unsupported! Please upgrade to Ruby 2.2.5 before installing Listen!

包管理器安装的ruby版本是ruby-2.1。所以我最终通过 RVM 安装 Ruby :

RUN gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 \
    && curl -sSL https://get.rvm.io | bash -s stable --ruby --gems=jekyll

它安装了 ruby-2.3 和 jekyll，它运行起来非常棒。
