I'm not a professional coder, but I like to build small tools with simple code. I don't know much about Go, and the only one tool that related to Go I ever downloaded and configured was goimapnotify, which I still use today in line with NeoMutt as an mail notifier on my macOS and Arch Linux.

I tried to install a static site generator gozzi with the following command, but kept receiving the same error:

╭╴  alowree on Arch Linux at ~
╰─❯ go install gitlab.com/tduyng/gozzi@latest
go: gitlab.com/tduyng/gozzi@latest: module gitlab.com/tduyng/gozzi: Get "https://proxy.golang.org/gitlab.com/tduyng/gozzi/@v/list": dial tcp 142.250.73.81:443: i/o timeout

What does this mean? What should I do next?

这个错误信息 dial tcp 142.250.73.81:443: i/o timeout 表明你的网络连接超时了。具体来说，go install 命令尝试访问默认的 Go 模块代理 proxy.golang.org 来下载 gozzi，但连接失败了。这通常是因为网络环境无法直接访问该代理服务。

🛠️ 解决方案：更换 Go 模块代理

既然原因是网络不通，最直接的解决方法就是为 Go 配置一个能稳定访问的模块代理。

更换代理：在终端中执行以下命令，将 GOPROXY 环境变量设置为国内常用的代理服务 https://goproxy.cn。
bash
```
╭╴  alowree on Arch Linux at ~
╰─❯ go env -w GOPROXY=https://goproxy.cn,direct
```

这里的 ,direct 是一个备选方案，表示如果代理无法获取模块，则直接从代码仓库（如 GitLab）下载。

重试安装命令：完成代理设置后，再次运行之前的安装命令即可。

bash

╭╴ alowree on Arch Linux at ~
╰─❯ go install gitlab.com/tduyng/gozzi@latest
go: downloading gitlab.com/tduyng/gozzi v0.1.6

go: downloading github.com/dlclark/regexp2 v1.11.5
go: downloading github.com/tdewolff/parse/v2 v2.8.5

设置完成后，go install 命令应该能够正常工作了。
