本文翻译自：Upgrade Node.js to the latest version on Mac OS

Currently I am using Node.js v0.6.16 on Mac OS X 10.7.4. 目前我在Mac OS X 10.7.4上使用Node.js v0.6.16。 Now I want to upgrade it to the latest Node.js v0.8.1. 现在我想将它升级到最新的Node.js v0.8.1。 But after downloading and installing the latest package file from nodejs.org, I found that system is still using v0.6.16 instead of v0.8.1 when I typed "node -v" in a terminal. 但是从nodejs.org下载并安装最新的软件包文件后，我发现当我在终端中输入“node -v”时，系统仍在使用v0.6.16而不是v0.8.1。 Is there any step that I have missed? 有没有我错过的一步？ Or, should I thoroughly uninstall the old version before installing the latest one? 或者，我应该在安装最新版本之前彻底卸载旧版本吗？

BTW, I know that nvm can help to manage the nodejs package 顺便说一句，我知道nvm可以帮助管理nodejs包

https://github.com/creationix/nvm/ https://github.com/creationix/nvm/

Is there any way to upgrade the Node.js without using it? 有没有办法升级Node.js而不使用它？

I have googled this problem, but it seems to me that there is no very clear answer to this question for the latest Node.js. 我已经搜索了这个问题，但在我看来，对于最新的Node.js，这个问题没有非常明确的答案。

If you initially installed Node.js with Homebrew , run: 如果您最初使用Homebrew安装Node.js ，请运行：

brew update
brew upgrade node
npm update -g npm

Or as a one-liner: 或者作为一个单行：

brew update && brew upgrade node && npm update -g npm

Note: If you have npm --version < 2.7.1, you should replace update (above) with install . 注意：如果你有npm --version <2.7.1，你应该用install替换update （上面）。

A convenient way to change versions is to use nvm : 更改版本的便捷方法是使用nvm ：

brew install nvm

To install the latest version of Node.js with nvm: 要使用nvm安装最新版本的Node.js：

nvm install node

---

If you installed via a package, then download the latest version from nodejs.org . 如果您通过软件包安装，则从nodejs.org下载最新版本。 See Installing Node.js and updating npm . 请参阅安装Node.js并更新npm 。

Go to http://nodejs.org and download and run the installer. 转到http://nodejs.org并下载并运行安装程序。 It works now - for me at least. 它现在起作用 - 至少对我来说。

You could install nvm and have multiple versions of Node.js installed. 您可以安装nvm并安装多个版本的Node.js.

curl https://raw.github.com/creationix/nvm/master/install.sh | sh
source ~/.nvm/nvm.sh

and then run: 然后运行：

nvm install 0.8.22  #(or whatever version of Node.js you want)

you can see what versions you have installed with : 您可以看到已安装的版本：

nvm list

and you can change between versions with: 你可以在以下版本之间进行更改：

nvm use 0.8.22

The great thing about using NVM is that you can test different versions alongside one another. 使用NVM的好处在于您可以并排测试不同的版本。 If different apps require different versions of Node.js, you can run them both. 如果不同的应用程序需要不同版本的Node.js，您可以同时运行它们。

2. sudo npm install -gn install n (this might take a while) sudo npm install -gn install n （这可能需要一段时间）
3. sudo n stable upgrade to the current stable version sudo n stable升级到目前的稳定版本

Note that sudo might prompt your password. 请注意， sudo可能会提示您输入密码。

Additional note regarding step 3: stable can be exchanged for latest , lts (long term support) or any specific version number such as 0.10.20 . 关于步骤3的附加说明： stable可以换成latest ， lts （长期支持）或任何特定版本号，例如0.10.20 。

If the version number doesn't show up when typing node -v , you might have to reboot. 如果在键入node -v时未显示版本号，则可能必须重新启动。
