R语言在Win10下lightGBM的成功安装

环境

* win10
* R version 3.4.3 (2017-11-30) – “Kite-Eating Tree”
* Platform: x86_64-w64-mingw32/x64 (64-bit)
* Microsoft Visual Studio Community 2017

* Microsoft Visual C++ 2017 (猜测需要)
* Visual Studio Tools for CMake (猜测需要)
* 在用VS打开\LightGBM\windows项目的时候，VS提示安装一些组件，不确定是哪些组件。
* cmake <https://cmake.org/download/> 64bit
* Rtools 64bit
系统环境变量PATH

* C:\RBuildTools\3.4\bin
* C:\Program Files\CMake\bin
* C:\Program Files\R\R-3.4.3\bin
其实CMake和VS不知道是否二选一。

安装

方法一
library(devtools) options(devtools.install.args = "--no-multiarch")
install_git("https://github.com/Microsoft/LightGBM", subdir = "R-package")
方法二
& 'C:\Program Files\R\R-3.4.3\bin\R.exe' CMD INSTALL --build . --no -multiarch
这样就直接安装好lightgbm包。另外也会在\LightGBM\R-package文件夹，也就是当前文件夹下生成了一个lightgbm_2.1.0.zip
文件，貌似在Rstudio下install.packages("d:/LightGBM/R-package/lightgbm_2.1.0.zip")
，系统提示不能安装，但是直接解压到扩展包的文件夹，然后重启Rstudio，扩展包lightgbm可以用，没问题。

方法三（未尝试）
devtools::install_github("Laurae2/lgbdl", force = TRUE) lgb.dl(commit =
"master", compiler = "vs", repo = "https://github.com/Microsoft/LightGBM")
如果已经有已编译好的lib_lightgbm.dll，可以这样：
lgb.dl(commit = "master", libdll = "C:\\LightGBM\\windows\\x64\\DLL\\
lib_lightgbm.dll",# YOUR PRECOMPILED DLL repo =
"https://github.com/Microsoft/LightGBM")
如果使用GPU：
lgb.dl(commit = "master", compiler = "vs", # Remove this for MinGW + GPU
installation repo ="https://github.com/Microsoft/LightGBM", use_gpu = TRUE)
