在CentOS 8上安装openblas

Question

我正在尝试在CentOS 8上安装R，它需要openblas-0.3.3-5.el8，但是使用dnf AppStream代码库只能给我openblas-0.3.3-2.el8。有没有办法强制它安装更新的版本？提前谢谢，我真的被困在这里了。

Answer 1

缺失的包位于一个名为powertools的代码库中，该代码库在Centos8上默认情况下是禁用的。您需要启用此存储库，然后重试。在我的GCP虚拟机上，我运行了：

sudo yum install epel-release
sudo yum config-manager --set-enabled powertools
sudo yum install R

Answer 2

我使用wget下载了新版本的openblas和openblas-thread。然后我可以安装它们，然后安装R。不知道为什么repo没有给我最新的版本，但我现在很好。
