我已经按照几个地方的说明在CentOS上安装了.Net SDK（Stream Release 9）。
为什么dotnet --info不显示已安装的SDK？
dotnet --info
eqzww0vc1#
当我试图从这个Microsoft page安装时，我没有成功。然后我试了这个：RUN dnf install dotnet-sdk-7.0 -y在此之后，我运行dotnet --info，输出如下：
RUN dnf install dotnet-sdk-7.0 -y

然后与dotnet --info我得到了这个（你可以在主机上观察到与你相同的提交Commit：8042 d 61 b17，所以这个版本可能对你有好处）。

无论如何，我可以猜测，在您的情况下，脚本没有设置正确的路径。请注意，我的架构是arm 64，与您的AMD 64不同。但是，您可以尝试上面的dnf命令。
dnf
玩转docker
如果你使用docker，你可以尝试在一个容器中安装dotnet（一个新的环境可能会有帮助），像这样：
FROM dokken/centos-stream-9 RUN dnf install dotnet-sdk-7.0 -y CMD [ "tail", "-f", "/dev/null" ]
构建图像：docker build -t centos-dot2 .运行图像：docker run --name cent centos-dot2命令后终端将挂起这个终端窗口（因为tail）然后，从另一个终端，在容器中输入：docker exec -it cent bash从这里可以运行dotnet --info最后，当您使用exit退出容器时，停止它并使用以下命令释放：docker rm -f cent也许这不是你想要的答案但不管怎样希望能帮上忙！Cose贝儿！
docker build -t centos-dot2 .
docker run --name cent centos-dot2
tail
docker exec -it cent bash
exit
docker rm -f cent
