1.安装npm与node。在cmd中使用这两个命令验证是否安装

C:\Users\z>node --version
v24.18.0

C:\Users\z>npm --version
11.16.0

2.安装claude code

2.1在cmd中使用这个命令

C:\Users\z>npm install -g @anthropic-ai/claude-code

一般返回一下内容：

added 2 packages in 17s npm warn allow-scripts 1 package has install scripts not yet covered by allowScripts: npm warn allow-scripts @anthropic-ai/claude-code@2.1.220 (postinstall: node install.cjs) npm warn allow-scripts npm warn allow-scripts Run `npm approve-scripts --allow-scripts-pending` to review, or `npm approve-scripts <pkg>` to allow.

2.2现在使用C:\Users\z>claude --version

'claude' is not recognized as an internal or external command, operable program or batch file.

2.3 将claude.cmd目录添加到path环境变量中

使用下面的命令

C:\Users\z>npm prefix -g

将输出的内容添加到环境变量中。

C:\Users\z>claude --version
2.1.220 (Claude Code)

3.将deepseek的api添加到claude的配置中

3.1在 Windows 系统中，路径为：C:\Users\你的用户名\.claude\

在该文件夹下找到或新建 settings.json 文件。

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.deepseek.com/anthropic",
    "ANTHROPIC_AUTH_TOKEN": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "ANTHROPIC_MODEL": "deepseek-v4-flash"
  }
}
填入以上内容，ANTHROPIC_AUTH_TOKEN为deepseek的API。

3.2验证

C:\Users\z>claude
