＜自用文兒在 Ubuntu 上安裝 Claude Code ＞發現了“京東云 JDCloude” 有國內商業云中最低的網絡性能

Claude Code：

最近刷屏這個詞：Claude Code 以后叫 CC，它是?Anthropic 的一款智能編程工具，幾個特點：

在終端運行?像使用命令行工具一樣，無需圖形用戶界面 GUI
深度理解整個代碼庫?
使用自然語言 讓其修復 bug、生成代碼、重構代碼、甚至運行測試。
代理式編程工具?"Agentic Coding Tool"?提供代碼建議，還能直接在你的開發環境中編輯文件并執行命令，實現自動化編程

總而言之，CC 就是在你終端里工作的 AI 助手，能理解你的代碼，并依照你給出的自然語言指令，來幫助你完成編寫、修改以及調試代碼。

可憐的京東云用戶：

在準備安裝環境時，我還以為 京東云輕量應用服務器 VPS?掉線了。看下面截圖：、

Apt 源都是清華，都是運行同樣的命令：

sudo apt update && sudo apt upgrade -y

這臺是 北京-騰訊云 4Mbps 帶寬 VPS:?2C2G50GB

這臺是 北京-京東云 帶寬?5Mbps,?VPS: 2C4G60GB

看看騰訊在小日本兒-京東?VPS：2C2G50GB 網絡 30Mbps

下面這個 VPS 在美國，1C1G10GB 網絡 50Mbps，不到?$13/yr 含一個公網IP

再看看從國外源的下載速度：

騰訊-北京云：

京東-北京云：

這就是我為什么開工單，要 “京東” 調整，說好的 5Mbps 帶寬，到了國際出口就 100.8Kbps ，只有?1/50 性能

開個工單：

運行商信息：

供應商	配置	帶寬	每月-流量	費用
京東-北京云	2C4G60GB	5Mbps	雙向 500GB	36個月：498/原價2459.16
騰訊-北京云	2C2G50GB	4Mbps	單向 1024GB	12個月：99元
騰訊-日本京東云	2C2G50GB	30Mbps	單向 300GB	12個月：99元
美國加州	1C1G10GB	50Mbps	雙向 512GB	12個月：不到 95元

注：C=CPU's core，G=內存，GB=硬盤

安裝 Claude Code

參考：Set up Claude Code - Anthropic??
????????? ?https://docs.anthropic.com/en/docs/claude-code/setup

1 確保 Ubuntu 24 是最新的系統

sudo apt update && sudo apt upgrade -y

2 安裝 Node.js 18以上的版本與 npm?

sudo apt remove nodejs npm
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs

校驗 Node.js / npm 安裝的版本：

node --version # Should show v20.x.x
npm --version  # Should show 10.x.x or higher

root@usw:~# sudo apt remove nodejs npm
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs

3 配置 npm

mkdir -p ~/.npm-global
npm config set prefix ~/.npm-global

添加路徑：

echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

添加依賴包（可選）

sudo apt install -y git ripgrep

4 安裝 CC

npm install -g @anthropic-ai/claude-code

5 啟動 CC

創建項目文件夾

mkdir ~/projects

復制項目到文件夾

root@usw:~/projects# ll
total 12
drwxr-xr-x  3 root root 4096 Jun 23 08:22 ./
drwx------ 12 root root 4096 Jun 23 08:25 ../
drwxr-xr-x  6 root root 4096 Jun 23 08:23 48.removebg/
root@usw:~/projects#

進入項目的文件夾中，運行 claude

root@usw:~/projects# cd 48.removebg/
root@usw:~/projects/48.removebg# claude?

claude

第一次運行 CC

1 配置顯示風格

柔光用 1，我最后選的 3 為了看清楚些。

2 訂閱用戶登錄或使用 API 付費

打折時付了年度會員，用的 1，如下：

用瀏覽器打開上面的鏈接，會拿到驗證碼：

粘貼到屏幕提示區

成功后，如圖：

下一頁，安全須知

3 進入項目

總結：

在沒有 GUI 的環境里 Claude Code 是一個玩美的終端上使用 AI 的方案。如果你也是 Claude 訂閱用戶（ Claude Pro ），你的 $20/月的 Claude Pro 訂閱本身就包含了在終端使用 Claude Code 的權限，并且會提供比免費用戶更多的使用量。?

如上圖中，Anthropic 也提供另一種方式：API 令牌使用費來使用 CC，這種按量付費模式獨立于你的 $20 訂閱，對于需要更高使用量、靈活或特定需求的用戶。

以上是在加州服務器運行，如果你的終端在國內，就要使用工具。

在國內安裝 CC

使用本地代理安裝 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 根據你自己的實際情況修改

最后把 npm anthropic 有關域加到路由，如： (以前有篇文章用 DELETED tunel 組網)

{"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"
}

修改后要重啟應用
