向dockerfile添加仓库

我正在尝试在我的Doker文件中添加DMLC repos，以便安装mxnet软件包。 我这样做如下：

RUN R -e "install.packages('drat', repos='https://cran.rstudio.com')" RUN R -e "drat::addRepo('dmlc')" RUN R -e "install.packages('mxnet', #repos='https://dmlc.github.io/drat', dependencies=TRUE)" 

这不起作用。 令人惊讶的是，我注意到，即使我添加了dmlc回购，实际上它不会被添加，当我打印出以下命令的输出：

 RUN R -e "print(getOption('repos'))" 

为了解决这个问题，我明确指定了回购协议，如下所示：

 #RUN R -e "install.packages('mxnet', #repos='https://dmlc.github.io/drat', dependencies=TRUE)" 

这仍然没有奏效。 它抛出一个错误说：

这是错误的截图

任何帮助？ 所有我想要做的是在准备我的容器时在我的Dockerfile中安装mxnet。

几点build议：

1. 在与Docker一起使用之前，请确保R命令在Dockerfile之外成功运行。 对于遇到的错误消息，该文件不存在，因此安装失败： http : //dmlc.ml/drat/src/contrib/mxnet_0.7.ta​​r.gz

2. 我在macOS X El Capitan上尝试了以下步骤，并且遇到了依赖包，rgexf和XML的错误。 但是，您可以检查下面的步骤是否在您的环境中正常工作？

https://mxnet.incubator.apache.org/get_started/install.html

  cran <- getOption("repos") cran["dmlc"] <- "https://s3-us-west-2.amazonaws.com/apache-mxnet/R/CRAN/" options(repos = cran) install.packages("mxnet") 

我遇到的错误：

 Error in download.file(url, destfile, method, mode = "wb", ...) : cannot download all files In addition: Warning message: In download.file(url, destfile, method, mode = "wb", ...) : URL 'https://s3-us-west-2.amazonaws.com/apache-mxnet/R/CRAN/src/contrib/mxnet_0.10.1.tar.gz': status was '404 Not Found' Warning in download.packages(pkgs, destdir = tmpd, available = available, : download of package 'mxnet' failed ... ... ... ERROR: dependency 'rgexf' is not available for package 'DiagrammeR' * removing '/usr/local/lib/R/3.3/site-library/DiagrammeR' The downloaded source packages are in '/private/var/folders/b2/d3rhxz3504q3q42dlx994wmnc9mg23/T/RtmpoUy7j7/downloaded_packages' Warning messages: 1: In install.packages("mxnet") : installation of package 'XML' had non-zero exit status 2: In install.packages("mxnet") : installation of package 'igraph' had non-zero exit status 3: In install.packages("mxnet") : installation of package 'rgexf' had non-zero exit status 4: In install.packages("mxnet") : installation of package 'DiagrammeR' had non-zero exit status 

然后，我试着：

 cran <- getOption("repos") cran["dmlc"] <- "https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/" options(repos = cran) install.packages("mxnet") Error in download.file(url, destfile, method, mode = "wb", ...) : cannot download all files In addition: Warning message: In download.file(url, destfile, method, mode = "wb", ...) : URL 'https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/src/contrib/mxnet_0.10.1.tar.gz': status was '404 Not Found' Warning in download.packages(pkgs, destdir = tmpd, available = available, : download of package 'mxnet' failed 

注意：这个错误不会暂停安装，直到我遇到这个错误：

 ** R ** demo ** inst ** preparing package for lazy loading ** help *** installing help indices ** building package indices ** testing if installed package can be loaded Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object '/usr/local/lib/R/3.3/site-library/igraph/libs/igraph.so': dlopen(/usr/local/lib/R/3.3/site-library/igraph/libs/igraph.so, 6): Library not loaded: @rpath/libxml2.2.dylib Referenced from: /usr/local/lib/R/3.3/site-library/igraph/libs/igraph.so Reason: image not found Error: loading failed Execution halted ERROR: loading failed * removing '/usr/local/lib/R/3.3/site-library/igraph' * restoring previous '/usr/local/lib/R/3.3/site-library/igraph' ERROR: dependency 'XML' is not available for package 'rgexf' * removing '/usr/local/lib/R/3.3/site-library/rgexf' ERROR: dependency 'rgexf' is not available for package 'DiagrammeR' * removing '/usr/local/lib/R/3.3/site-library/DiagrammeR' 

这些步骤可能适用于您的操作系统和环境。 所以请尝试一下，在这里发表你的发现。

后来，我在github上发现了这个问题。 所以，你可以在那里跟踪这个问题：
