It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:

当前回答

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)"

其他回答

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。

我尝试了上面的方法 导出路径= / opt /组装/ bin:美元的道路 但是没有用。

所以我做了我的研究,并意识到上述代码适用于苹果芯片Mac,而不是英特尔芯片Mac。

所以我对代码进行了编辑,因为我的Mac是基于英特尔的,我这样做了,工作完美:

在查找器中,打开/编辑.zshrc文件,如果找不到,则创建一个。 粘贴以下代码:

导出路径= / usr /地方/组装/ bin:美元的道路

会有用的!!

你的电脑上已经安装了自制软件。你需要像这样修改你的PATH:

export PATH=/usr/local/bin:$PATH

或者从起始点执行brew:

/usr/local/bin/brew install maven

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)"

编辑.zshrc文件:

nano .zshrc

并在文件的开头添加以下内容:

export PATH=/opt/homebrew/bin:$PATH

保存并运行:

source ~/.zshrc
