当前回答

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

其他回答

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 

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

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。

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
