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

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

我是这么做的:

curl https://raw.githubusercontent.com/creationix/nvm/v0.20.0/install.sh | bash
cd / && . ~/.nvm/nvm.sh && nvm install 0.10.35
. ~/.nvm/nvm.sh && nvm alias default 0.10.35

这款没有自制啤酒。

NVM很快将支持io.js，但现在还不支持:https://github.com/creationix/nvm/issues/590

然后用包安装每个项目的其他所有东西。Json和NPM安装。

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。

使用zsh和Homebrew安装:

brew install nvm  <=== This is not recommended by NVM. They want to run their shell script instead

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

然后将以下内容添加到~/。ZSHRC或您所需的shell 配置文件:

export NVM_DIR="$HOME/.nvm"
. "/usr/local/opt/nvm/nvm.sh"

然后安装一个节点版本并使用它。

nvm install 7.10.1
nvm use 7.10.1
