我正在尝试使用renv::install().

通常，我会使用

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

指定 icudt61l.zip 依赖项的位置。我怎样才能在 renv 中做到这一点？

我试图添加ICUDT_DIR='path/to/icudt61l.zip/'我的 .Rprofile 但它没有用。

知道如何告诉 renv ICU 在哪里安装 stringi 吗？

这是我得到的错误

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

只需使用此命令，即可从本地加载 ICUDT。如果你运行这一切都有错误，在 icudt 中无法连接。你应该遵循这个 https://raw.githubusercontent.com/gagolews/stringi/master/INSTALL。

像这样跟随：

ICU 数据库和无法上网

请注意，如果您选择使用我们的 ICU4C 捆绑包，那么 - 默认情况下 - ICU 数据库将从我们的镜像服务器之一下载。但是，如果您已经下载了icudt*.zip适合您平台的版本（大/小端），您可能希望通过调用来安装该软件包：

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

此外，如果您在尝试安装 stringi 的机器上无法访问ICUInternet，请尝试获取该软件包的最新开发版本，因为它与数据存档一起提供。您可以通过省略文件中的一些相关行来构建包含所有必需的 ICU 数据文件（供离线使用）的可分发源包.Rbuildignore。以下命令序列应该可以解决问题：

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

假设该软件包的最新开发版本编号为 xyz，stringi_x.y.z.tar.gz则在当前工作目录中创建一个名为的文件。现在可以通过执行以下命令来安装包（源包可以通过 scpetc. 传播）：

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

或者，从 R 会话中调用：

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

来自?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")

设置类似：

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

应该有希望让你摆脱困境。
