根据Homebrew网站，要安装它，我需要输入:
brew install wget
我得到一个错误消息:
-bash: brew: command not found
找到了这个答案。然而，问题是我在/usr/local/bin中没有看到brew。
我在.bashrc文件中添加了下面这行代码
export PATH=/usr/local/bin:$PATH
仍然得到命令未找到错误。
如何在macOS上安装Homebrew ?

打开终端，输入下面的命令。 安装:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
卸载:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
一旦安装完成后，输入brew命令:
brew install wget
brew install node
brew install watchman

Brew现在已经用Bash重写了!
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
在终端中添加以下内容，单击“enter”，然后按照终端中的说明操作。/usr/bin/ruby -e "$(curl - ssl https://raw.githubusercontent.com/Homebrew/install/master/install)"
如果运行后仍然报错，
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
然后尝试从https://developer.apple.com/download/more/下载并安装命令行工具，适用于特定的Mac os和Xcode版本。
然后试着跑，
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
然后
brew install node
解决“-bash: brew:命令未找到”问题
将Homebrew添加到/Users//.bash_profile中的PATH:
echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users//.bash_profile . sh
eval $(/opt/homebrew/bin/brew shellenv)
检查是否安装了Xcode:
$ gcc --version
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
$ brew doctor
$ brew update
