检查是否安装了Xcode:

$ gcc --version

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

$ brew doctor

$ brew update

首先，在MAC终端上粘贴命令来安装自制程序

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

然后编辑你的.bashrc文件

vi .bashrc

在最后粘贴下面的命令并保存它

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

要保存，只需输入:wq并按enter

如果bashrc文件不存在，则只需创建并编辑该文件，以创建类型

touch ~/.bashrc

然后简单地运行命令

source ~/.bashrc

现在尝试使用brew命令，希望它现在可以工作了

更新:如果你使用的是M1 mac，那么在安装homebrew后，只需运行下面提到的命令并重新加载终端

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

Brew现在已经用Bash重写了!

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

检查是否安装了Xcode:

$ gcc --version

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

$ brew doctor

$ brew update

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)"

macOS 大苏尔

必须将此添加到终端cmd，以使Brew运行。

将Homebrew添加到/Users/*username/.zprofile中的PATH: echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/*username/.zprofile Eval $(/opt/homebrew/bin/brew shellenv)

*username =您的本地机器用户名
