用rstan在摇杆/诗句上构建Docker图像

我打算运行一个定制的Rstudio，其中tidyverse,和rstan预装在Digital Ocean的Docker 17.03.0-ce on 16.04上。用rstan在摇杆/诗句上构建Docker图像

在Docker Hub上，已经有一个预建的图像：Rocker/verse具有tidyverse和的功能。所以我的计划是简单地获取最新版本的Rocker/verse并添加一个新层rstan。我使用的jonzelner/rstan和jrnold/rstan的dockerfile和如下更新它们：

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

然而，我试图建立这一形象（docker build -t image_name .）在错误结束。以下提供的结果：

大约有non-zero exit status有内存做一个包中的一些类似的问题，所以我想提高我的本地计算机上的内存泊坞窗，但仍没有运气。我能做些什么来成功构建这个图像吗？

正如你在错误输出中看到，在安装过程中无法找到编译：

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

请注意，这是试图在一个rocker/verse容器安装clang-3.6输出：

[email protected]:/# 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.

看起来这个图片在它的仓库中没有出现Clang 3.6。而这个名字改为python-clang-3.6; Clang绑定Python编程语言。

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
