R 在 renv 中安装包 stringi

Question

我正在尝试使用 renv::install() 安装包 stringi。

一般情况下，我会用

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

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

我尝试在我的 .Rprofile 中添加 ICUDT_DIR='path/to/icudt61l.zip/' 但没有成功。

知道如何告诉 renv ICU 在哪里安装 stringi 吗？

这是我得到的错误

Answer 1

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

只需要使用这个命令，就可以从本地加载ICUDT。如果你运行这一切都有错误，在 icudt 中无法连接。你应该按照这个 https://raw.githubusercontent.com/gagolews/stringi/master/INSTALL .

如下所示:

ICU 数据库和无法访问互联网

请注意，如果您选择使用我们的 ICU4C bundle ，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，如果您已经下载了适合的 icudt*.zip 版本对于您的平台(大/小端)，您可能希望安装通过调用打包:

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

此外，如果您在计算机上无法访问互联网您尝试安装 stringi，尝试获取最新的开发版本包的，因为它与 ICU 数据文件一起运送。您可以构建一个可分发的源包，其中包含所有必需的ICU 数据文件(供离线使用)通过省略一些相关行.Rbuildignore 文件。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

假设包的最新开发版本编号为 x.y.z，在当前工作目录中创建一个名为 stringi_x.y.z.tar.gz 的文件。现在可以安装包(源包可以通过scp 等)通过执行:

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

或者，从 R session 中调用:

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