Determining fastest mirrors Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 12: Timeout on http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock: (28, 'Resolving timed out after 30580 milliseconds') One of the configured repositories failed (未知), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> or subscription-manager repos --disable=<repoid> 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64

这个错误表明您的系统无法连接到CentOS的镜像源。您可以尝试以下解决方法来解决这个问题:
1. 检查您的网络连接是否正常,尝试使用ping命令测试您的网络连接。
2. 检查您的系统DNS配置是否正确,可以尝试使用nslookup命令测试DNS解析是否正常。
3. 检查您的防火墙设置,确保防火墙没有阻止yum连接到镜像源。
4. 尝试使用备用镜像源,可以通过编辑CentOS的yum源配置文件,将默认的镜像源更改为其他可用的镜像源来解决问题。
5. 如果您使用的是代理,请确保代理设置正确并且不会阻止yum连接到镜像源。
希望这些解决方法可以帮助您解决问题。

这个错误通常是由于您的系统无法连接到软件源导致的。建议您检查您的网络连接是否正常,并确保您的系统可以访问正确的软件源。
您可以尝试清除缓存并重新更新软件源:
```
sudo yum clean all
sudo yum update
```
如果问题仍然存在,您可以尝试更改软件源。您可以编辑`/etc/yum.repos.d/CentOS-Base.repo`文件,并将`baseurl`字段更改为可用的软件源。

根据提供的日志信息,您的Live Coding编译过程中出现了错误。根据日志,看起来是在编译 "MyActor.cpp" 文件时发生了问题,并报告了一个C2059错误。
C2059错误是编译错误,通常与语法有关。这可能是由于以下几个原因引起的:
1. 语法错误:请检查 "MyActor.cpp" 文件的语法,确保没有遗漏的分号、括号或其他语法错误。
2. 编译器版本不匹配:请确保您使用的编译器版本与项目所需的版本兼容。根据日志,您使用的是Visual Studio 2022 14.33.31631版本。
3. 依赖问题:请检查您的项目依赖项是否正确配置,并且所有需要的库和资源都已正确安装。
要更准确地确定问题所在,我建议您查看更详细的编译日志(Log.txt),以获取更多关于错误的上下文信息。这将有助于确定错误的具体原因,并采取相应的修复措施。
