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

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。

下面是我做的步骤。

1.安装自酿酒

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

2.运行brew help,看看它是否工作…如果显示错误“zsh: command not found: brew”,请继续执行。

修改路径为:

echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/"YOUR USER NAME"/.zprofile

记得把“用户名”改成你的, 然后输入:

eval $(/opt/homebrew/bin/brew shellenv)

成功运行这些命令后,键入“brew help”查看是否一切正常。

确保先安装brew

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

在您的.zshrc文件中,将路径添加到您的homebrew/bin,无论它可能在哪里。在我的例子中,homebrew安装在我的主目录中。 添加:

export PATH="/<path-to-homebrew-directory>/bin:$PATH"

重新启动终端,让它接收到.zshrc的更改

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
