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)

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
...
...

就在家酿网站主页的顶部。

终端提示符:

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

命令brew install wget演示了如何在已经安装brew之后使用Homebrew安装另一个应用程序(在本例中是wget)。

历史……

在大约2020年之前，Homebrew页面上给出的命令是:

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

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)"

如果你使用的是m1芯片mac，那么在安装homebrew后运行以下命令并再次打开终端:

echo "export PATH=/opt/homebrew/bin:$PATH" >> ~/.zshrc

不知道为什么没有人提到这一点:当你从官方网站运行安装命令时，在最后几行你会看到如下内容，你需要遵循==>下一步:

==> Installation successful!

==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
  https://docs.brew.sh/Analytics
No analytics data has been sent yet (or will be during this `install` run).

==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
  https://github.com/Homebrew/brew#donations

==> Next steps:
- Add Homebrew to your PATH in /Users/{YOUR USER NAME}/.bash_profile:
    echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/{YOUR USER NAME}/.bash_profile
    eval $(/opt/homebrew/bin/brew shellenv)

这是bash shell的。对于每个不同的shell，您将看到不同的步骤，但是这些步骤的源是相同的。
