It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
    ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
The current contents of /usr/local are bin CODEOFCONDUCT.md etc git lib Library LICENSE.txt munki README.md sbin share .git .github .gitignore
➜  ~ brew install maven
zsh: command not found: brew

当前回答

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 

其他回答

确保先安装brew

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

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)"

因为你正在使用zsh,你需要添加路径到你的。zshrc文件:

vim ~ / . zshrc

Add:

export BREW_HOME="/home/linuxbrew/.linuxbrew/bin"
export PATH="$PATH:$BREW_HOME"

我将演示来自@Spindizzy的答案:

cd ~ | ls -a
touch .zshrc // if file .zshrc doesn't exists we create it
vim .zshrc

将PATH=/opt/homebrew/bin:$PATH粘贴到那里,保存文件并重启终端。

Vim助手:

1. press "i" to interactive mode in vim, paste:
export PATH=/opt/homebrew/bin:$PATH
2. press "esc" type ":wq" and hit enter

我在macOS Big Sur(11.0.1)上遇到了类似的问题。在我的例子中,homebrew保存在/opt/homebrew/,而不是/usr/local/....

所以我补充道

导出路径= / opt /组装/ bin:美元的道路

到我的主目录中的.zshrc文件,并且ZSH shell能够找到brew命令。
