docker build 中缺少 R X13binary

Question

我有一个 docker 文件，我正在尝试安装 R 季节性库：

FROM continuumio/miniconda3:4.5.12 # Debian

. . .

# Install packages not on conda
RUN conda activate r_env && \
    R -e "install.packages(c('RUnit', 'seasonal'), dependencies=TRUE, repos='https://cran.case.edu')"

一切看起来都安装正确，但是当我进入容器并运行 library(seasonal) 时，我得到了错误：

> library(seasonal)
The binaries provided by 'x13binary' do not work on this
machine. To get more information, run:
  x13binary::checkX13binary()

> x13binary::checkX13binary()
Error in x13binary::checkX13binary() : X-13 binary file not found

经过一番谷歌搜索后，我似乎可以手动设置二进制文件的路径，并且 findutil 显示该二进制文件存在于机器上：

(r_env) root@89c7265d9316:/# find / -name "*x13*"

/opt/conda/pkgs/r-x13binary-1.1.39_2-r36h6115d3f_0.tar.bz2

但是，无论我将路径设置为什么，库仍然会在实际路径所在的位置引发错误：

(r_env) root@89c7265d9316:/# export X13_PATH=/opt/conda/envs/arimaApiR/lib/R/library/x13binary
(r_env) root@89c7265d9316:/# R -e "library(seasonal)"

The system variable 'X13_PATH' has been manually set to:
  /opt/conda/envs/arimaApiR/lib/R/library/x13binary
Since version 1.2, 'seasonal' relies on the 'x13binary'
package and does not require 'X13_PATH' to be set anymore.
Only set 'X13_PATH' manually if you intend to use your own
binaries. See ?seasonal for details.
Binary executable file /opt/conda/envs/arimaApiR/lib/R/library/x13binary/x13as or /opt/conda/envs/arimaApiR/lib/R/library/x13binary/x13ashtml not found.
See ?seasonal for details.

我觉得我在兜圈子。有没有人幸运地在容器中运行它？

Answer 1

我已经准备好自己的容器，但我没有使用 continuumio/miniconda，因为我不知道它在里面是如何工作的。

这是我准备的 Dockerfile：

FROM r-base:3.6.1

RUN apt-get update \
    && apt-get install -y libxml2-dev

RUN R -e "install.packages('RUnit', dependencies=TRUE, repos='https://cran.case.edu')"
RUN R -e "install.packages('x13binary', dependencies=TRUE, repos='https://cran.case.edu')"
RUN R -e "install.packages('seasonal', dependencies=TRUE, repos='https://cran.case.edu')"

CMD [ "bash" ]

如果我运行你的测试命令，我会收到：

> library(seasonal)
> x13binary::
x13binary::checkX13binary     x13binary::supportedPlatform  x13binary::x13path            
> x13binary::checkX13binary
x13binary::checkX13binary
> x13binary::checkX13binary()
x13binary is working properly
> 

注意：Dockerfile 可以改进，例如你可以把包放在一起c(RUnit, x13binary, seasonal)，你可以在安装包后删除apt缓存，但我只是想运行一个测试看看它是否可以工作。
