使用nvm安装Node.js，而不是Homebrew

在大多数回答中，推荐使用Homebrew安装nvm。

不要这样做。

在nvm的Github上，Readme清楚地说:

不支持自制程序安装。如果你对homebrew安装的nvm有问题，请先卸载它，然后按照下面的说明进行安装，然后再提交问题。

请使用下面的方法

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

脚本将nvm存储库克隆到~/。NVM并将源行添加到概要文件(~/。bash_profile、~ /。zshrc ~ /。或者~/.bashrc)。

然后使用nvm安装node。例如，要安装最新的LTS版本，请:

nvm install 16

干净，没有麻烦。它会把这个设置为你的默认Node.js版本，所以你应该都设置好了。

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

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

安装自酿酒

用于酿造

"$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

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
