嘿，@huangbz2007！很高兴再次见到你。希望一切都好。

这个问题可能是由于网络问题或者Python包索引(PyPI)暂时慢或不可用导致的。以下是一些解决此问题的步骤：

1. 重试安装：有时候，简单地在短暂等待后重试命令就可以解决问题，因为这可能只是一个临时的网络故障或PyPI服务器问题。

2. 增加超时时间：你可以通过添加--http-timeout选项并设置一个更高的秒数值来增加poetry install命令的超时时间。例如，要将超时设置为300秒（5分钟），你需要在Makefile中修改install_backend目标为：

   install_backend:
       poetry install --extras deploy --http-timeout 300
   

   这样可以给操作更多的时间来完成，而不会因超时而中断。

3. 使用不同的镜像：如果问题仍然存在，使用一个响应更快的PyPI的不同镜像可能会有所帮助。你可以通过运行以下命令来配置Poetry使用不同的镜像：

   poetry config repositories.<name> <mirror-url>
   poetry config http-basic.<name> <username> <password> # 如果需要身份验证
   

   然后，修改install_backend目标以使用指定的镜像：

   install_backend:
       poetry install --extras deploy -r <name>
   

   将<name>替换为你在poetry config repositories.<name>命令中使用的名称，将<mirror-url>替换为镜像的URL。

4. 检查你的互联网连接：确保你的互联网连接稳定，并且你没有处于可能阻止或减慢你连接到PyPI的代理或防火墙后面。

5. 更新Poetry：确保你正在使用最新版本的Poetry，因为更新通常包括性能改进和错误修复。你可以通过运行以下命令来更新Poetry：

   poetry self update
   

如果在尝试了这些步骤后你仍然遇到"Read timed out"错误，那么可能值得检查PyPI的状态（https://status.python.org/）以查看是否有任何已知问题，或者如果你怀疑是你无法控制的网络相关问题，可以联系你的网络管理员。
