r - 在 R 中安装最新版本的 xgboost 时出错

问题描述

嗨，尝试时遇到以下错误

    `install.packages("xgboost")`

错误信息：

`In file included from amalgamation/xgboost-all0.cc:68:0:

 xgboost::LearnerImpl::SaveModel(xgboost::Json*) const’:

但是，可以安装较旧的存档版本

packageurl <- "http://cran.r- 
project.org/src/contrib/Archive/xgboost/xgboost_0.90.0.2.tar.gz"
install.packages(packageurl, repos=NULL, type="source")

解决方案

如果您是从源代码构建的，也许值得通过命令行（https://xgboost.readthedocs.io/en/latest/build.html#installing-the-development-version）从 github 尝试开发包：

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
mkdir build
cd build
cmake .. -DR_LIB=ON
make -j$(nproc)
make install
