Mac安装Homebrew

使用Homebrew官网命令去安装的伙伴们一定遇到过这样的问题，当你在Mac的terminal终端粘贴从Homebrew官网上复制的安装命令后，terminal输入如下

~ $ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to raw.githubusercontent.com:443

如何解决呢？

制作Homebrew安装脚本

打开链接：
https://raw.githubusercontent.com/Homebrew/install/master/install

若打不开网页，出现下图情况：

打开terminal终端输入

~ $ sudo vim /etc/hosts

并正确输入Mac的密码，打开vim后按 i进入编辑模式，新起一行输入199.232.96.133 raw.githubusercontent.com，然后按esc 并输入 :wq，如下图所示:

回车。
重新点击上面链接，网页如下图：

把网页内容Command + a全选，Command + c复制下来，打开terminal终端输入

~ $ vim brew_install

打开vim后，Command + v粘贴上去，然后按esc 并输入 :wq，如下图所示

然后回车，我们的Homebrew安装脚本brew_install就做好了。

修改Homebrew安装脚本权限

修改Homebrew安装脚本brew_install文件权限，terminal终端输入如下命令：

~ $ chmod 755 brew_install

回车。

执行Homebrew安装脚本

执行Homebrew安装脚本brew_install，terminal终端输入如下命令：

~ $ ./brew_install

回车。若terminal终端输入如下：

~ $ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to raw.githubusercontent.com:443

打开一个新终端Command + n，多次尝试输入如下指令

~ $ ./brew_install

直到terminal输出如下：

Warning: The Ruby Homebrew installer is now deprecated and has been rewritten in
Bash. Please migrate to the following command:/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"Password:

正确输入你Mac密码，回车，输出如下：

Mac更新Homebrew

你可能会遇到这种情况，当你在terminal中输入命令 brew install XXX安装服务时，总是有如下输出：

Updating Homebrew...

运气好可能更新成功，运气不好就各种报错，这时该怎么办呢？答案就是根据我的安装教程重新卸载并安装Homebrew。

卸载Homebrew
