也许你已经从homebrew主页上遵循了这一步。

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

所以可能你的系统不能分配路径，所以遵循以下步骤。

sudo nano /etc/paths

粘贴

/opt/homebrew/bin:$PATH

保存并关闭

运行以下设置，然后就可以使用brew了

执行unintsall脚本:-

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

设置Git Compression:- Git config——global core.compression 0

设置Git缓冲区大小:- Git config——global http。postBuffer 1048576000

运行安装脚本:— /bin/bash -c $(curl - ssl https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

对于此错误，zsh: command not found: brew

确保你已经安装了Brew，用这个(等待它完成安装) (编辑:在结尾添加了结尾引用)

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

然后遵循命令行上显示的NEXT STEPS，它应该显示如下所示

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

在相同的终端窗口上复制并粘贴第一行，然后按enter键

echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/$USER/.zprofile

然后在同一终端窗口复制并粘贴最后一行，然后按enter键

eval $(/opt/homebrew/bin/brew shellenv)

最后，您应该能够使用brew帮助，如果有效，则意味着brew已正确安装并从ZSH运行。

在我的MacBook (macOS Big Sur V 11.0.1)安装Homebrew后，我也遇到了同样的问题。

安装完成后，在控制台中会显示应该做什么:

==>下一步: -将Homebrew添加到/Users/USER/.zprofile中的PATH: echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/USER/.zprofile . sh Eval $(/opt/homebrew/bin/brew shellenv) -运行“brew help”开始

按顺序执行这两个命令，会将brew命令添加到PATH:

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/USER/.zprofile

eval "$(/opt/homebrew/bin/brew shellenv)"

请访问Homebrew官方网站。

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

下一个步骤:

test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)
test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
test -r ~/.bash_profile && echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.bash_profile
echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.profile

尝试:brew install hello

在Apple M1的fish shell中，我必须将/opt/homebrew/bin添加到fish_user_paths全局环境中。我必须手动这样做，因为set -U fish_user_paths /opt/homebrew/bin $fish_user_paths got

设置:通用变量fish_user_paths被同名的全局变量遮蔽。
