R在renv中安装包stringi

Question

我正在尝试用renv::install()安装这个软件包。

正常情况下，我会用

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

若要指定icudt61l.zip相关性的位置，请执行以下操作。我怎么才能在这里做这件事？

我试图在我的.Rprofile中添加ICUDT_DIR='path/to/icudt61l.zip/'，但是它没有工作。

你知道怎么告诉idea在哪里安装stringi吗？

这是我所犯的错误

Answer 1

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

只需使用此命令，即可从本地加载ICUDT。如果您运行这一切都有错误，在icudt中connect.You应该遵循这个https://raw.githubusercontent.com/gagolews/stringi/master/INSTALL。

就像这样：

ICU数据库和无因特网接入

请注意，如果您选择使用我们的ICU4C包，那么--默认情况下--将从镜像服务器下载ICU数据库。但是，如果您已经下载了适合您的平台(大号/小终端)的icudt*.zip版本，您可能希望通过以下方式安装该软件包：

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

此外，如果您在试图安装的机器上没有internet access，请尝试获取包的最新开发版本，因为它是随ICU数据存档一起提供的。您可以通过省略.Rbuildignore文件中的一些相关行来构建一个可分发的源代码包，该包包含所有所需的ICU数据文件(供脱机使用)。下面的命令序列应该可以做到这一点：

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，则在当前工作目录中创建一个名为stringi_x.y.z.tar.gz的文件。现在可以安装包了(源包可以通过scp传播等等)。通过执行：

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)
