可能会迟到,但肯定会有帮助。你必须首先安装brew。只要运行下面的命令就可以了:

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

其他回答

更新2023

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

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。

确保先安装brew

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

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

今天早上我也遇到了同样的问题。问题是自制程序的路径设置不正确。

遵循以下步骤

1.正确安装自制软件。在cmd下面的终端类型中。

ruby / usr / bin / e,“美元(卷毛-fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

在.zshrc文件中设置终端类型的路径 打开~ / . zshrc 在.zshrc文件中添加如下路径 导出路径= " / usr /地方/ bin:美元路径” 在终端类型源~/.zshrc 这样就完成了。
