安装brew后我得到`命令not found：brew`

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

我对MacOS的大苏尔类似的问题（11.0.1）。在我的情况自制保存在/opt/homebrew/，而不是在/usr/local/...。

因此，我增加

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

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

Answer 2

对于这个错误zsh: command not found: brew

1. 确保您已经安装了 Brew（等待安装完成）

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

2. 然后按照命令行上显示的NEXT STEPS，它应该显示如下

==> 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)

3. 将第一行复制并粘贴到同一终端窗口中，然后按 Enter 键

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

4. 然后将最后一行复制并粘贴到同一终端窗口中，然后按 Enter 键

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

最后，您应该可以使用 brew help，如果可以使用，则意味着 brew 已正确安装并从 ZSH 运行。

Answer 3

Homebrew已安装在您的计算机上。你需要修改你的PATH：

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

或从其来源执行brew：

/usr/local/bin/brew install maven

Answer 4

这是我做的步骤...

1.安装自制软件

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

2.运行 brew help 并查看它是否正常工作...如果显示错误“zsh: command not found: brew”，请继续操作。

3. 将路径更改为：

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

记得把“USER NAME”改成你的， 然后输入：

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

成功运行这些命令后，输入“brew help”以查看是否一切正常。

Answer 5

在我的 MacBook (macOS Big Sur V 11.0.1) 中安装 Homebrew 后，我遇到了同样的问题。

安装后，在控制台它会说应该做什么，

==> Next steps:
- Add Homebrew to your PATH in /Users/samme/.zprofile:
    echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/samme/.zprofile
    eval $(/opt/homebrew/bin/brew shellenv)
- Run `brew help` to get started

依次执行以上两条命令，会将brew命令添加到PATH中。

Answer 6

在 Apple M1 的 fish shell 中，我必须将 /opt/homebrew/bin 添加到 fish_user_paths 全局环境。我必须手动执行此操作，因为 set -U fish_user_paths /opt/homebrew/bin $fish_user_paths 得到了

set: 通用变量 'fish_user_paths' 被同名的全局变量遮蔽。

Answer 7

只需在您的主目录中添加 export PATH=/opt/homebrew/bin:$PATH

如果需要重新启动或重新打开您的终端

Answer 8

检查以下链接，您可以在那里设置 Homebrew (brew) 命令，并在 .zshrc 文件中设置永久设置路径

可能会迟到，但肯定会有所帮助。您必须首先安装brew。只需运行以下命令即可：

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

Answer 11

如果您使用 WSL2，请确保遵循 linuxbrew 的最终 linux installation instructions。

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

Answer 12

转到官方Homebrew site。

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

后续步骤：

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

试试：brew install hello

Answer 13

基本上你的自制软件保存在 /opt/homebrew/ 中，而不是 /usr/local/.... 路径

在您的主目录中打开 .bash_profile 并添加：

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

并重新启动终端。您将启动并运行它。
