什么是 ClaudeCode

ClaudeCode是我们所称的 Agentic Coding Tool，简称 Coding Agent。

Read、Write、Bash、Git，模型输出到预定工具，预定工具执行任务，执行完后输出给模型作为输入，反复交互完成人们指定的任务内容。

过去几年，众多AI编程工具相继涌现，如 Github Copilot、Cursor、Windsurf、Cursor、CodeX等等。

软件工程并不会消失，但我们构建软件的方式已经改变，并将持续演进。

Coding Agent就像伐木工的 油锯，从斧头到手锯，再到油锯 电锯，工具一直在变，没人做10年软件工程师后仍然会对个简单的CRUD API的构建感到最初那样的兴奋，只会觉得无聊。这样的内容全世界的软件工程师已经写了百万千万次数十亿百亿次，LLM早就具备了输出类似代码的能力。

首次启动claude后，会尝试连接到 api.anthropic.com, 之后提示地区不支持

在 ~/.claude.json 文件中添加以下内容

"hasCompletedOnboarding": true

然后再运行就可以了

设置环境变量

为claude加环境变量
