我是在使用cc switch管理claude key的时候突然出现的，更新node版本什么的好像也会出现这种情况，这只是最通用的方法，重装（

Claude command not found

我就直接重装claude了，记录一下步骤

1. 先npm install -g @anthropic-ai/claude-code
2. 然后发现报错：npm error code ENOTEMPTY npm error syscall rename npm error path /opt/homebrew/lib/node\_modules/@anthropic-ai/claude-code npm error dest /opt/homebrew/lib/node\_modules/@anthropic-ai/.claude-code-2DTsDk1V npm error errno -66 npm error ENOTEMPTY: directory not empty, rename '/opt/homebrew/lib/node\_modules/@anthropic-ai/claude-code' -> '/opt/homebrew/lib/node\_modules/@anthropic-ai/.claude-code-2DTsDk1V' npm error A complete log of this run can be found in: {redacted}
3. 开始删除重装：sudo rm -rf /opt/homebrew/lib/node\_modules/@anthropic-ai/claude-code
4. npm cache clean --force
5. npm install -g @anthropic-ai/claude-code
6. claude --version
7. 然后就成功了
