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

其他回答

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。

也许不是很明显,但是除了上面的步骤之外,检查您的.zshprofile是否被任何多余的引号损坏。您还应该关闭所有终端实例。

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 

确保先安装brew

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

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)"
