安装自制后，我得到“zsh：命令未找到：酿造”

Question

➜  ~ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
-e:77: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040677
It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
    ruby -e "$(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

Answer 1

Homebrew已安装在您的计算机上。您需要像这样修改您的PATH：

export PATH=/usr/local/bin:$PATH

或从其来源执行brew：

/usr/local/bin/brew install maven

Answer 2

1. 确保您已经安装了Brew，使用它（等待它完成安装）（编辑：在末尾添加结尾引号）

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

==> Next steps:
- Add Homebrew to your PATH in /Users/$USER/.zprofile:
    echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/$USER/.zprofile
    eval $(/opt/homebrew/bin/brew shellenv)

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

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

最后，您应该能够使用< code>brew help，如果成功，这意味着brew已正确安装并从< code>ZSH运行。

Answer 3

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

所以我补充道

导出PATH=/opt/homebrew/bin:$PATH

至<代码>。zshrc文件，ZSH shell能够找到brew命令。
