对于m1 mac，使用该命令重新启动终端。

echo "export PATH=/opt/homebrew/bin:$PATH" >> ~/.zshrc .

在一个开箱即用的MacOS High Sierra 10.13.6

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

给出以下错误:

curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

解决方案:只要在你的卷曲选项中添加一个k

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

下面是一个将自制程序安装程序包装在bash函数中的版本，可以从部署脚本中运行:

install_homebrew_if_not_present() {
    echo "Checking for homebrew installation"
    which -s brew
    if [[ $? != 0 ]] ; then
        echo "Homebrew not found. Installing..."
        ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    else
        echo "Homebrew already installed! Updating..."
        brew update
    fi
}

另一个函数将安装一个自制公式，如果它还没有安装:

brew_install () {       
    if brew ls --versions $1 > /dev/null; then
        echo "already installed: $1"
    else
        echo "Installing forumula: $1..."
        brew install $1
    fi
}

一旦你定义了这些函数，你可以在你的bash脚本中像下面这样使用它们:

install_homebrew_if_not_present
brew_install wget
brew_install openssl
...

您可以使用以下命令安装brew。

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

然而，当使用这个你会得到警告，它购买自制安装程序现在已弃用。建议改用Bash。

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

如何设置你的Mac为家酿

步骤1

检查你已经安装了Xcode。在终端上运行下面的命令

/usr/bin/xcodebuild -version

它将打印以下示例输出:

Xcode 12.3 Build version 12C33

步骤2

现在打开Xcode:

选择偏好 选择位置选项卡 现在在命令行工具中从下拉菜单中选择你的Xcode版本

步骤3

在终端运行以下命令:

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

注意:如果你有M1芯片Mac运行下面的命令，关闭终端，再打开终端

echo "export PATH=/opt/homebrew/bin:$PATH" >> ~/.zshrc

解决“-bash: brew:命令未找到”问题

将Homebrew添加到/Users//.bash_profile中的PATH:

echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users//.bash_profile . sh

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