Using homebrew install nvm: brew update brew install nvm source $(brew --prefix nvm)/nvm.sh Add the last command to the .profile, .bashrc or .zshrc file to not run it again on every terminal start. So for example to add it to the .profile run: echo "source $(brew --prefix nvm)/nvm.sh" >> ~/.profile If you have trouble with installing nvm using brew you can install it manually (see here) Using nvm install node or iojs (you can install any version you want): nvm install 0.10 # or nvm install iojs-1.2.0 npm is shipping with node (or iojs), so it will be available after installing node (or iojs). You may want to upgrade it to the latest version: $ npm install -g npm@latest UPD Previous version was npm update -g npm. Thanks to @Metallica for pointing to the correct way (look at the comment bellow). Using npm install ionic: npm install -g ionic What about ngCordova: you can install it using npm or bower. I don't know what variant is more fit for you, it depends on the package manager you want to use for the client side. So I'll describe them both: Using npm: Go to your project folder and install ng-cordova in it: npm install --save ng-cordova Using bower: Install bower: npm install -g bower And then go to your project folder and install ngCordova in it: bower install --save ngCordova

PS

某些命令可能需要超级用户权限 npm install some_module的简写是npm i some_module

我同意noa——如果你需要拥有多个版本的node, io.js，那么brew不是合适的解决方案。

你可以在nvm中帮助beta测试io.js支持:https://github.com/creationix/nvm/pull/616

如果你只想要io.js，并且不切换版本，那么你可以从https://iojs.org/dist/v1.0.2/iojs-v1.0.2-darwin-x64.tar.gz安装io.js的二进制发行版;这包括NPM，如果你不切换版本，你将不需要NVM。

记得在安装后更新npm: sudo npm install -g npm@latest

如果您之前使用brew安装了节点，那么在以“正确的方式”安装节点之前，您将有一堆额外的文件需要清理。另外，我必须在启动脚本中添加一些设置，以使工作顺利进行。

我写了一个脚本来简化这个过程。

我在这里写了一篇短文，详细说明为什么这是“正确的方式”。

如果你需要安装iojs，可以像这样使用nvm:

nvm install iojs-v1.7.1

要安装brew，只需查看其主页。

看alexpods回答其余的问题。

我使用n(节点版本管理)

您可以通过两种方式安装它

brew install n

or

npm install -g n

您可以在不同版本的node和io之间进行切换。下面是一个来自我当前env的例子，当我不带参数地调用n时:

$ n

  io/3.3.1
  node/0.12.7
  node/4.0.0
  node/5.0.0
ο node/5.10.1 

2021年更新

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

MAC故障处理:

从macOS 10.15开始，默认shell是zsh, nvm将寻找.zshrc来更新，默认情况下没有安装。用touch ~/创建一个。ZSHRC并再次运行安装脚本。

如果您使用bash(前面的默认shell)，则运行touch ~/。Bash_profile来创建必要的配置文件(如果不存在)。

您可能需要重新启动终端实例或运行。~ / .nvm / nvm.sh。重新启动终端/打开新选项卡/窗口，或运行source命令将加载该命令和新配置。

您以前使用过bash，但是安装了zsh。您需要手动将这些行添加到~/。ZSHRC并运行。~ / . zshrc。

我已经很晚了，但我不喜欢其他的答案

安装node和npm

你不应该使用brew来安装node和npm。

我看到过一些地方建议你应该使用Homebrew来安装Node(比如alexpods的答案和在这个Team Treehouse博客文章中)，但是这样安装你更容易遇到问题，因为npm和brew都是包管理器，你应该有一个包管理器来管理另一个包管理器，这就会导致问题，就像这个官方npm问题错误:拒绝删除:/usr/local/bin/npm或这个无法在OSX上卸载npm模块

你可以在DanHerbert的帖子中阅读更多关于这个话题的内容，在Mac OS X上为Homebrew用户修复npm

此外，使用npm的Homebrew安装将要求你在安装全局包时使用sudo。因为Homebrew背后的核心思想之一是应用程序可以在不给予root访问权限的情况下安装，这是一个坏主意。

对于其他事情

我会使用npm;但你真的应该按照每个模块的安装说明，按照他们网站上的说明，因为他们会比其他人更清楚他们有任何问题或错误
