Question

我尝试使用以下方法在我的Linux服务器上安装xgboost R软件包：

install.packages("xgboost", lib = "/usr/lib64/R/library")

它给了我一个错误：

它表示需要g ++ - 4.6或更高版本。

我将服务器上的gcc从4.4.7更新为4.9.2。但是，它仍然给我同样的错误。

有没有人对这个问题有所了解。怎么解决这个问题？

Answer 1

为R准备好较新版本gcc和g++的一种方法是强制它在系统$PATH的早期出现。除了更改$PATH之外，还可以使用/usr/local/bin/通常在/usr/bin之前发布的事实，以便首选新版本。

因此，我们在gcc我们可以做的

中安装了新的/opt/gcc/gcc-4.9.2/

cd /usr/local/bin
sudo ln -s /opt/gcc/gcc-4.9.3/bin/gcc .
sudo ln -s /opt/gcc/gcc-4.9.3/bin/g++ .

这可能就足够了。可以添加ld，as，ar，...，但并非总是需要。根据需要调整路径，并确保将实际可执行文件（即gcc）链接到/usr/local/bin。

选中gcc --version。

我有xgboost安装问题。但是，可以安装较旧的存档版本（'0.90.0.2'），并且可以运行！

packageurl <- "http://cran.r- 
project.org/src/contrib/Archive/xgboost/xgboost_0.90.0.2.tar.gz"

install.packages(packageurl, repos=NULL, type="source")

在linux中为R安装xgboost时出错
