Question

我打算在Digital Ocean的tidyverse上预先安装rmarkdown，rstan和Docker 17.03.0-ce on 16.04来定制Rstudio。

在Docker Hub上，已经有一个预构建的图像：Rocker/verse具有tidyverse和rmarkdown功能。所以我的计划是简单地获取最新版本的Rocker/verse并添加一个新的rstan图层。我使用jonzelner/rstan和jrnold/rstan的dockerfile并按如下所示更新它们：

FROM rocker/verse:latest

# Install essentials
RUN apt-get update \ 
    && apt-get install -y --no-install-recommends \
                   clang-3.6

# Global site-wide config
RUN mkdir -p $HOME/.R/ \
    && echo "\nCXX=clang++ -ftemplate-depth-256\n" >> $HOME/.R/Makevars \
    && echo "CC=clang\n" >> $HOME/.R/Makevars

# Install rstan
RUN install2.r --error \
    inline \
    RcppEigen \
    StanHeaders \
    rstan \
    KernSmooth

# Config for rstudio user
RUN mkdir -p /home/rstudio/.R/ \
    && echo "\nCXX=clang++ -ftemplate-depth-256\n" >> /home/rstudio/.R/Makevars \
    && echo "CC=clang\n" >> /home/rstudio/.R/Makevars \
    && echo "CXXFLAGS=-O3\n" >> /home/rstudio/.R/Makevars \
    && echo "\nrstan::rstan_options(auto_write = TRUE)" >> /home/rstudio/.Rprofile \
    && echo "options(mc.cores = parallel::detectCores())" >> /home/rstudio/.Rprofile

# Install loo
RUN install2.r --error \
    matrixStats \
    loo

但是，我构建此图片（docker build -t image_name .）的尝试以错误方式结束。结果如下：

关于具有non-zero exit status的包的一些类似问题与内存有关，所以我试图增加本地机器上的Docker内存，但仍然没有运气。有什么办法可以成功建立这个图像吗？

正如您在错误输出中看到的那样，安装过程找不到编译器：

/bin/bash: clang++: command not found

请注意，这是尝试在clang-3.6容器中安装rocker/verse的输出：

root@8ea0d98e67c3:/# apt-get install -y --no-install-recommends clang-3.6
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'python-clang-3.6' for regex 'clang-3.6'
0 upgraded, 0 newly installed, 0 to remove and 15 not upgraded.

看来这个图像并没有在其存储库中附带Clang 3.6。而这个名称反而指向python-clang-3.6;用于Python编程语言的Clang绑定。

除非你绝对想要3.6，否则我会安装指向3.5的普通clang包，然后重新运行Docker构建过程。

apt-get install clang

使用rstan在摇杆/诗歌上构建Docker镜像
