R：无法从 GitHub 安装“treeshap”

Question

我正在使用 R 编程语言。我正在尝试从 github 安装以下 R 库：https://rdrr.io/github/ModelOriented/treeshap/

按照本网站的说明，我复制并粘贴了以下代码来安装这个库（我在 CRAN 上找不到这个库）：

install.packages("remotes")
remotes::install_github("ModelOriented/treeshap")

但是，这会产生以下消息和错误：

Downloading GitHub repo ModelOriented/treeshap@HEAD
These packages have more recent versions available.
It is recommended to update all of them.
Which would you like to update?

 2: CRAN packages only

谁能告诉我我做错了什么？

错误：包“treeshap”编译失败

问题是编译错误。此外，我们看到：

sh: c:/rtools40/mingw32/bin/g++: 没有那个文件或目录

编译失败，因为找不到g++。一个好的起点是查看您的机器上是否存在c:/rtools40。如果没有，Using Rtools40 on Windows 文章可能会有所帮助。
