如何彻底卸载Node.js，而后从头开始从新安装（Mac OS X）

问题：

My version of node is always v0.6.1-pre even after I install brew node and NVM install v0.6.19. 个人节点版本始终是v0.6.1-pre，即便我安装了brew节点而且NVM也安装了v0.6.19。

My node version is: 个人节点版本是：

node -v
v0.6.1-pre

NVM says this (after I install a version of node for the first time in one bash terminal): NVM这样说（我在一个bash终端中第一次安装了一个版本的节点以后）：

nvm ls
v0.6.19
current:    v0.6.19

But when I restart bash, this is what I see: 可是当我从新启动bash时，这是我看到的：

nvm ls
v0.6.19
current:    v0.6.1-pre
default -> 0.6.19 (-> v0.6.19)

So where is this phantom node 0.6.1-pre version and how can I get rid of it? 那么这个幻影节点0.6.1-pre版本在哪里，我该如何摆脱它？ I'm trying to install libraries via NPM so that I can work on a project. 我正在尝试经过NPM安装库，以即可以在项目上工做。

I tried using BREW to update before NVM, using "brew update" and "brew install node". 我尝试使用BREW在NVM以前进行更新，使用“ brew update”和“ brew install node”。 I've tried deleting the "node" directory in my /usr/local/include and the "node" and "node_modules" in my "/usr/local/lib". 我尝试删除/ usr / local / include中的“节点”目录以及“ / usr / local / lib”中的“节点”和“ node_modules”。 I've tried uninstalling npm and reinstalling it following these instructions. 我已尝试按照如下说明卸载npm并从新安装。

All of this because I was trying to update an older version of node to install the "zipstream" library. 全部这些都是由于我试图更新节点的旧版本以安装“ zipstream”库。 Now there's folders in my users directory, and the node version STILL isn't up to date, even though NVM says it's using 0.6.19. 如今，个人用户目录中有文件夹，而且节点版本STILL不是最新的，即便NVM表示它正在使用0.6.19。

Ideally, I'd like to uninstall nodejs, npm, and nvm, and just reinstall the entire thing from scratch on my system. 理想状况下，我想卸载nodejs，npm和nvm，而后从头开始从新安装整个系统。
