# 在Mac OS X下卸载Node.js

因为[准备nodejs开发环境](/cloud-atlas-draft/develop/nodejs/startup/nodejs_develop_environment.md)，准备从头开始，所以想要卸载掉原先通过`pkg`安装的node.js，然后重新通过`nvm`来管理node.js版本。

对于实用官方pkg安装包，使用如下命令卸载

```
cd /
lsbom -f -l -s -pf /var/db/receipts/org.nodejs.node.pkg.bom \
| while read i; do
  sudo rm ${i}
done
sudo rm -rf /usr/local/lib/node \
     /usr/local/lib/node_modules \
     /var/db/receipts/org.nodejs.*
```

> 注意，首先要检查一下 `lsbom -f -l -s -pf /var/db/receipts/org.nodejs.node.pkg.bom` ，确保删除掉的文件是 `/usr/local/include/node/...` 这样的文件，避免误删
