无法在 Windows 7 上安装支持 GPU 的 R XGBoost

我尝试在 Windows 7 上的 R 中安装具有 GPU 支持的 XGBoost。我按照此处的安装指南进行操作（http://xgboost.readthedocs.io/en/latest/build.html#installing-r-package-with-gpu-support http://xgboost.readthedocs.io/en/latest/build.html#installing-r-package-with-gpu-support）直到最后一步一切都很好。我花了几天时间进行搜索，但找不到解决方案。有人能帮帮我吗？

这是我在 Git Bash 中遵循的过程：

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
mkdir build
cd build
cmake .. -G"Visual Studio 14 2015 Win64" -DUSE_CUDA=ON -DR_LIB=ON -DLIBR_EXECUTABLE="C:/Program Files/R/R-3.4.1/bin/x64/R.exe"
cmake --build . --target install --config Release

最后一步出现以下错误

"C:\Users\geng\xgboost\build\install.vcxproj" (default target) (1) ->

如果我执行这个（cmake --build . --target xgboost --config Release），没有错误。但是，我不知道从这里我应该做什么。如果我只是做这样的事情：

cd R-package
"C:/Program Files/R/R-3.4.2/bin/R.exe" CMD INSTALL .

它以如下所示的不同错误结束。我不知道我做错了什么，非常感谢您的帮助。预先非常感谢您！

没关系，我已经找到原因了。这与我的 Rtools 设置有关。我重新安装它并确保 PATH 有以下两项，然后问题解决。

c:\Rtools\bin;c:\Rtools\mingw_64\bin
