确保先安装brew

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

其他回答

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)"

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

16.11.2022 -更新 在brew安装期间,我得到了多行通知我将在哪里安装brew。终端对我说:

This script will install:
...
/usr/local/Homebrew

我需要的路径是最后一个。解决问题的步骤:

编辑.zshrc文件。类型: 纳米~ / . zshrc 在编辑器中添加一行: 导出路径= / usr /地方/组装/ bin:美元的道路 点击Control+X退出编辑器,Y接受更改,返回接受文件将保存的位置。

毕竟,您需要刷新您使用的终端。您可以关闭它的进程并打开或键入:

来源 ~/.zshrc

就是这样!希望有帮助。

它帮助我。只需运行follow命令:

echo '# Set PATH, MANPATH, etc., for Homebrew.' >> /Users/gureenkov56/.zprofile
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/gureenkov56/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

如果您使用的是WSL2,请确保遵循linuxbrew的最终linux安装说明。

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
