R 在 renv 中安裝 package stringi

Question

我正在嘗試使用renv::install()安裝 package stringi。

通常，我會使用

install.packages('stringi', configure.vars='ICUDT_DIR=path/to/icudt61l.zip/')

指定 icudt61l.zip 依賴的位置。 我怎樣才能在 renv 中做到這一點？

我試圖在 my.Rprofile 中添加ICUDT_DIR='path/to/icudt61l.zip/'但它沒有用。

知道如何告訴 renv ICU 在哪里安裝 stringi 嗎？

這是我得到的錯誤

Answer 1

install.packages("stringi", configure.vars="ICUDT_DIR=<icudt_dir>")

只需使用此命令，即可從本地加載 ICUDT。 如果你運行這一切都有錯誤，在icudt中無法連接。你應該按照這個https://raw.githubusercontent.com/gagolews/stringi/master/INSTALL 。

像這樣跟隨：

ICU 數據庫和無法上網

請注意，如果您選擇使用我們的 ICU4C 捆綁包，那么 - 默認情況下 - ICU 數據庫將從我們的鏡像服務器之一下載。 但是，如果您已經下載了適合您的平台（大/小端）的icudt*.zip版本，您可能希望通過調用以下方式安裝 package：

install.packages("stringi", configure.vars="ICUDT_DIR=<icudt_dir>")

此外，如果您在嘗試安裝 stringi 的機器上無法訪問Internet，請嘗試獲取 package 的最新開發版本，因為它與ICU數據存檔一起提供。 您可以通過省略.Rbuildignore文件中的一些相關行來構建包含所有必需 ICU 數據文件（供離線使用）的可分發源 package。 以下命令序列應該可以解決問題：

wget https://github.com/gagolews/stringi/archive/master.zip -O stringi.zip
unzip stringi.zip
sed -i '/\/icu..\/data/d' stringi-master/.Rbuildignore
R CMD build stringi-master

假設 package 的最新開發版本編號為 xyz，則在當前工作目錄中創建一個名為stringi_x.yztar.gz的文件。 現在可以通過執行以下命令安裝 package（源包可以通過scp等傳播）：

R CMD INSTALL stringi_x.y.z.tar.gz

或者，從 R session 中調用：

install.packages("stringi_x.y.z.tar.gz", repos=NULL)

Answer 2

從?renv::install ：

Package Configuration:

     Many R packages have a 'configure' script that needs to be run to
     prepare the package for installation. Arguments and environment
     variables can be passed through to those scripts in a manner
     similar to install.packages. In particular, the R options
     'configure.args' and 'configure.vars' can be used to map package
     names to their appropriate configuration. For example:

     # installation of RNetCDF may require us to set include paths for netcdf
     configure.args = c(RNetCDF = "--with-netcdf-include=/usr/include/udunits2"))
     options(configure.args = configure.args)
     renv::install("RNetCDF")

     Similarly, additional flags that should be passed to R CMD INSTALL
     can be set via the 'install.opts' R option:

     # installation of R packages using the Windows Subsystem for Linux
     # may require the `--no-lock` flag to be set during install
     options(install.opts = "--no-lock")
     renv::install("xml2")

設置類似：

options(configure.vars = list(stringi = "ICUDT_DIR=path/to/icudt61l.zip"))

應該有希望讓你擺脫困境。
