原因：

1. Node.js 版本过低：@anthropic-ai/claude-code 需要 Node.js 18.0.0 或更高版本，而当前使用的是 v12.22.9。（具体看报错信息）
2. 权限不足：没有足够的权限在 /usr/local/lib/node_modules 目录下创建文件。

解决方式

1. 升级 Node.js 版本
   首先需要将 Node.js 升级到 18.0.0 或更高版本。可以使用 nvm（Node Version Manager）来管理 Node.js 版本：

# 安装 nvm（如果尚未安装）
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

# 重新加载终端或运行
source ~/.bashrc  # 或 ~/.zshrc，取决于你的 shell

# 安装并使用 Node.js 18
nvm install 18
nvm use 18

配置 npm 使用用户目录：

mkdir -p ~/.npm-global/lib ~/.npm-global/bin
npm config set prefix "/home/ps/.npm-global"
npm install -g @anthropic-ai/claude-code
npm list -g --depth=0
claude --version
