1.Hmonebrew安装

homebrew官网, 移除brew

安装

# 这里不能使用root权限
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" 

# 安装成功后检查brew版本
brew --version
Homebrew 2.2.14

# 安装成功，后面重点要把源 切到 aliyun、USTC中科大、tsinghua清华等国内源； 记住有问题先看官网！这种工具官网要是讲不清楚怎么用，会被吐槽死的~
#所以一定要先看官网

移除homebrew

当homebrew遇到问题时可以移除重装。 移除方法如下：

# 问题：homebrew安装时遇到问题，
Homebrew must be run under Ruby 2.6
# 先安装brew install Ruby@2.6 或者 rvm安装？
Updating Homebrew...
# 一直卡住了， 我感觉应该直接把brew卸载重装
# 根据官网的方法，移除brew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
# 问题，这网址被墙了, 搜一个域名对应的ip 配置一下host可以了
curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused
# 重试
sudo /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

# 当重新安装brew时，情况会是这样的，brew会帮你搞定一切

域名被墙了

配置好域名和ip映射，重试ok

切换国内源

我使用的是这个

cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-science"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-science.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-python"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-python.git

brew update

记得执行 source ~/.bash_profile

其他源的切换方法看这里，源切换方法，每种方法有点小区别。

查看源

brew config

# 设置成功

CLT: 10.3.0.0.1.1562985497
Xcode: 8.2.1
XQuartz: 2.7.7 => /opt/X11

遇到问题，重新配置完后验证一下，再次查看brew config ok。

这样 homebrew 基本就没问题了，后续使用brew安装软件会比较快。

2.Go安装

golang 官网需要翻下

问题排除

brew install go 失败，看来brew源有问题，

换一个中科大的试试，没问题了。

这个开始正确的，开始安装。

安装过程

www.jianshu.com/p/287fc9c7d…

HOMEBREW_BOTTLE_DOMAIN 貌似不是影响brew search，这个Formulae（库）各方应该都是一样的。

安装成功后，查看go版本

go version
go version go1.14.2 darwin/amd64

配置环境变量

open /usr/local/Cellar/go/
然后看一下自己的libexec在什么地方然后记录下整体的地址 我的地址是
/usr/local/Cellar/go/1.14.2_1/libexec

需要将这部分写入到 vim ~/.bash_profile

#GO
#GOROOT
export GOROOT=/usr/local/Cellar/go/1.14.2_1/libexec
#GOPATH
export GOPATH=$HOME/Documents/FEWoekSpace/golearn
#Bin
export PATH=${PATH}:$GOPATH/bin

好习惯， source ~/.bash_profile

验证

hello world

赶紧试试go环境是否已经ok了...

创建helloworld.go 写入下面内容

package main  // 代码包声明语句。
import "fmt" //系统包用来输出的

func main() {
    // 打印函数调用语句。用于打印输出信息。
   fmt.Println("helloworld")
}

然后执行

go run helloworld.go

开始学习go吧
