随机森林安装失败

Question

我尝试在 CentoOS 6 机器上的 R 中安装 randomForest 包，如下所示：

install.packages("/var/installation_files/randomForest_4.6-12.tar.gz", repos = NULL, type="source")

但是，它抛出以下错误：

> install.packages("/var/installation_files/randomForest_4.6-12.tar.gz", repos = NULL, type="source")
* installing *source* package ‘randomForest’ ...

有人可以帮助解决这个问题吗？

按照此处的说明启用我们安装的 devtoolset-2 后，这工作正常：https://unix.stackexchange.com/questions/175851/how-to-permanently-enable-scl-centos-6-4

之后我就可以安装 R 包了
