我有一堆软件包的源文件及其依赖关系,我想在没有互联网访问的计算机上安装.我想在其他计算机上使用U盘安装所有这些,但某些软件包的安装失败,因为在软件包之前没有安装依赖项.在需要它们的包之前,我如何获得依次安装的顺序？
这是我目前的方法来获取包,它们的依赖关系,并按照正确的顺序来获取它们：
# find the dependencies for the packages I want
# from https://stackoverflow.com/a/15650828/1036500
getPackages <- function(packs){
packages <- unlist(
tools::package_dependencies(packs,available.packages(),which=c("Depends","Imports"),recursive=TRUE)
)
packages <- union(packages,packs)
packages
}
# packages I want
my_packages <- c('stringr','devtools','ggplot2','dplyr','tidyr','rmarkdown','knitr','reshape2','gdata')
# get names of dependencies and try to get them in the right order,this seems ridiculous...
my_packages_and_dependencies <- getPackages(my_packages)
dependencies_only <- setdiff(my_packages_and_dependencies,my_packages)
deps_of_deps <- getPackages(dependencies_only)
deps_of_deps_of_deps <- getPackages(deps_of_deps)
my_packages_and_dependencies <- unique(c(deps_of_deps_of_deps,deps_of_deps,dependencies_only,my_packages))
# where to keep the source?
local_CRAN <- paste0(getwd(),"/local_CRAN")
# get them from CRAN,source files
download.packages(pkgs = my_packages_and_dependencies,destdir = local_CRAN,type = "source")
# note that 'tools','methods','utils,'stats',etc. art not on CRAN,but are part of base
# from https://stackoverflow.com/a/10841614/1036500
library(tools)
write_PACKAGES(local_CRAN)
现在假设我在另一台电脑上安装了R和RStudio(和Rtools或Xcode),没有互联网连接,我插上USB棒,打开RProj文件来设置工作目录,并运行这个脚本：
#############################################################
## Install from source (Windows/OSX/Linux)
# What do I want to install?
my_packages_and_dependencies <- c("methods","tools","bitops","stats","colorspace","graphics","tcltk","Rcpp","digest","jsonlite","mime","RCurl","R6","stringr","brew","grid","RColorBrewer","dichromat","munsell","plyr","labeling","grDevices","utils","httr","memoise","whisker","evaluate","rstudioapi","roxygen2","gtable","scales","proto","MASS","assertthat","magrittr","lazyeval","DBI","stringi","yaml","htmltools","caTools","formatR","highr","markdown","gtools","devtools","ggplot2","dplyr","tidyr","rmarkdown","knitr","reshape2","gdata")
# where are the source files?
local_CRAN <- paste0(getwd(),"/local_CRAN")
# scan all packages and get files names of wanted source pckgs
# I've got other things in this dir also
wanted_package_source_filenames <- list.files(local_CRAN,pattern = "tar.gz",full.names = TRUE)
# put them in order to make sure deps go first,room for improvement here...
trims <- c(local_CRAN,"/","tar.gz")
x1 <- gsub(paste(trims,collapse = "|"),"",wanted_package_source_filenames)
x2 <- sapply( strsplit(x1,"_"),"[[",1)
idx <- match(my_packages_and_dependencies,x2)
wanted_package_source_filenames <- na.omit(wanted_package_source_filenames[idx])
install.packages(wanted_package_source_filenames,repos = NULL,dependencies = TRUE,contrib.url = local_CRAN,# I thought this would take care of getting dependencies automatically...
type = "source" )
这工作相当不错,但仍然有一些软件包无法安装：
sapply(my_packages_and_dependencies,require,character.only = TRUE)
methods tools bitops stats
TRUE TRUE TRUE TRUE
colorspace graphics tcltk Rcpp
TRUE TRUE TRUE TRUE
digest jsonlite mime RCurl

R6 stringr brew grid

gtools devtools ggplot2 dplyr

Warning messages:
1: In library(package,lib.loc = lib.loc,character.only = TRUE,logical.return = TRUE,:
there is no package called ‘RCurl’
2: In library(package,:

4: In library(package,:

5: In library(package,:

6: In library(package,:

似乎编织者必须在rmarkdown之前进行,在tidyr和ggplot2之前重塑2等.
必须有一个更简单和更完整的解决方案来获取源文件列表的问题,需要按照正确顺序放置所有依赖关系.最简单的方法是什么(不使用任何贡献的包)？
这是我目前正在开发的系统,我正在使用源版本的软件包来试图为离线计算机(OSX / Linux / Windows)做任何事情做准备：

编辑以下Andrie的有用的评论,我已经与miniCRAN一起去,从小插曲中缺少的是如何从本地的repo实际安装包.这是我试过的：
library("miniCRAN")
# Specify list of packages to download
pkgs <- c('stringr','gdata')
# Make list of package URLs
revolution <- c(CRAN="http://cran.revolutionanalytics.com")
pkgList <- pkgDep(pkgs,repos=revolution,type="source" )
pkgList
# Set location to store source files
local_CRAN <- paste0(getwd(),"/local_CRAN")
# Make repo for source
makeRepo(pkgList,path = local_CRAN,repos = revolution,type = "source")
# install...
install.packages(pkgs,repos = local_CRAN,# do I really need "file:///"?
dependencies = TRUE,type = "source" )
结果是：
Installing packages into ‘C:/emacs/R/win-library/3.1’ (as ‘lib’ is unspecified) Warning in install.packages : unable to access index for repository C:/Users/.../local_CRAN/src/contrib Warning in install.packages : packages ‘stringr’,‘devtools’,‘ggplot2’,‘dplyr’,‘tidyr’,‘rmarkdown’,‘knitr’,‘reshape2’,‘gdata’ are not available (for R version 3.1.2)
我在这里缺少什么？
编辑是的,我没有正确使用file：///,它应该是这样的：
install.packages(pkgs,repos = paste0("file:///",local_CRAN),type = "source")
这让我感到震惊,这一切基本上都是按预期的方式工作的.非常感谢.现在我只是想看看：致命错误：curl / curl.h：没有这样的文件或目录,这是阻止RCurl和httr安装.
miniCRAN包可以帮助这个.您可以告诉miniCRAN您想要安装的软件包列表,然后找出依赖关系,下载这些软件包,并在本地计算机上创建一个名为CRAN的存储库,即它遵守install.packages()等.

> Available on CRAN
>阅读vignette
>我们正在积极开发miniCRAN.跟踪进度,并在github miniCRAN repository找到最新的开发版本
>请参阅project wiki链接到演示文稿,博客文章等
要从本地的miniCRAN存储库安装,您有两个选项.
>首先,你可以使用URI约定文件：///.例如
install.packages("ggplot2",repos="file:///path/to/file/")
>或者,您可以将目标配置为HTTP服务器,并通过URL使您的存储库可用.在这种情况下,您的本地存储库将看起来和感觉完全一样,就像一个CRAN镜像,除了它只包含你想要的包.
