Claude Code：
最近刷屏这个词：Claude Code 以后叫 CC，它是 Anthropic 的一款智能编程工具，几个特点：
- 在终端运行 像使用命令行工具一样，无需图形用户界面 GUI
- 深度理解整个代码库
- 使用自然语言 让其修复 bug、生成代码、重构代码、甚至运行测试。
- 代理式编程工具 "Agentic Coding Tool" 提供代码建议，还能直接在你的开发环境中编辑文件并执行命令，实现自动化编程
总而言之，CC 就是在你终端里工作的 AI 助手，能理解你的代码，并依照你给出的自然语言指令，来帮助你完成编写、修改以及调试代码。
可怜的京东云用户：
在准备安装环境时，我还以为 京东云 轻量应用服务器 VPS 掉线了。看下面截图：、
Apt 源都是清华，都是运行同样的命令：
sudo apt update && sudo apt upgrade -y这台是 北京-腾讯云 4Mbps 带宽 VPS: 2C2G50GB
这台是 北京-京东云 带宽 5Mbps, VPS: 2C4G60GB
看看腾讯在小日本儿-京东 VPS：2C2G50GB 网络 30Mbps
下面这个 VPS 在美国，1C1G10GB 网络 50Mbps，不到 $13/yr 含一个公网IP
再看看从国外源的下载速度：
腾讯-北京云：
京东-北京云：
这就是我为什么开工单，要 “京东” 调整， 说好的 5Mbps 带宽，到了国际出口就 100.8Kbps ，只有 1/50 性能
开个工单：
运行商信息：
| 供应商 | 配置 | 带宽 | 每月-流量 | 费用 |
| 京东-北京云 | 2C4G60GB | 5Mbps | 双向 500GB | 36个月：498/原价2459.16 |
| 腾讯-北京云 | 2C2G50GB | 4Mbps | 单向 1024GB | 12个月：99元 |
| 腾讯-日本京东云 | 2C2G50GB | 30Mbps | 单向 300GB | 12个月：99元 |
| 美国加州 | 1C1G10GB | 50Mbps | 双向 512GB | 12个月：不到 95元 |
注：C=CPU's core，G=内存，GB=硬盘

1 配置显示风格
柔光用 1，我最后选的 3 为了看清楚些。
2 订阅用户登录或使用 API 付费
打折时付了年度会员，用的 1，如下：
用浏览器打开上面的链接，会拿到验证码：
粘贴到屏幕提示区
成功后，如图：
下一页，安全须知
3 进入项目
总结：
在没有 GUI 的环境里 Claude Code 是一个玩美的终端上使用 AI 的方案。如果你也是 Claude 订阅用户 （ Claude Pro ），你的 $20/月的 Claude Pro 订阅本身就包含了在终端使用 Claude Code 的权限，并且会提供比免费用户更多的使用量。
如上图中，Anthropic 也提供另一种方式：API 令牌使用费来使用 CC，这种按量付费模式独立于你的 $20 订阅，对于需要更高使用量、灵活或特定需求的用户。
以上是在加州服务器运行，如果你的终端在国内，就要使用工具。
在国内安装 CC
使用本地代理安装 Claude Code
npm config set proxy http://127.0.0.1:1081
npm config set https-proxy http://127.0.0.1:1081
npm install -g @anthropic-ai/claude-code注: socket port 1081 根据你自己的实际情况修改
最后把 npm anthropic 有关域加到路由，如： (以前有篇文章 用 DELETED tunel 组网)
{
"type": "field",
"domain": [
"registry.npmjs.org",
"*.npmjs.org",
"npmjs.com",
"*.npmjs.com",
"anthropic.com",
"*.anthropic.com",
"console.anthropic.com",
"api.anthropic.com",
"claude.ai",
"*.claude.ai"
],
"outboundTag": "usw_outbound"
}修改后要重启应用
下面是日志反映出主机路由的变化，BJN:

这样在北京的主机上就可以使用 CC 来维护代码
