**Go** （或**golang** ）是由Robert Griesemer，Rob Pike和Ken Thompson于2007年在Google创建的一种编程语言。它是Algol和C传统中的一种编译的静态类型语言。它具有垃圾收集，有限的结构类型，内存安全性以及添加的CSP风格的并发编程功能。最初由Google开发的编译器和其他语言工具都是免费和开源的。它的受欢迎程度越来越快。它是构建Web应用程序的绝佳选择。

## ##预安装：
|
|||
|
|
|
|||
|
|
#### 使用Homebrew安装Golang：
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ brew update
|
|||
|
|
$ brew install golang
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
#### 安装后，尝试运行go版本以查看已安装的Go版本。
|
|||
|
|
|
|||
|
|
## ###设置工作区：
|
|||
|
|
|
|||
|
|
##### 添加环境变量：
|
|||
|
|
|
|||
|
|
首先，您需要告诉Go您工作区的位置。
|
|||
|
|
|
|||
|
|
我们将一些环境变量添加到shell配置中。其中一个文件位于您的主目录bash\_profile，bashrc或.zshrc（对于Oh My Zsh Army）
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ vi .bashrc
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
\`
|
|||
|
|
|
|||
|
|
然后添加这些行以导出所需的变量
|
|||
|
|
|
|||
|
|
#### 这实际上是你的.bashrc文件
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
export GOPATH=$HOME/go-workspace # don't forget to change your path correctly!
|
|||
|
|
export GOROOT=/usr/local/opt/go/libexec
|
|||
|
|
export PATH=$PATH:$GOPATH/bin
|
|||
|
|
export PATH=$PATH:$GOROOT/bin
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## ####创建工作区：
|
|||
|
|
|
|||
|
|
##### 创建工作区目录树：
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ mkdir -p $GOPATH $GOPATH/src $GOPATH/pkg $GOPATH/bin
|
|||
|
|
$GOPATH/src : Where your Go projects / programs are located
|
|||
|
|
$GOPATH/pkg : contains every package objects
|
|||
|
|
$GOPATH/bin : The compiled binaries home
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 快速开始
|
|||
|
|
|
|||
|
|
对于快速入门和样板Go项目，请尝试使用[Alloy](https://www.growthmetrics.io/open-source/alloy)
|
|||
|
|
|
|||
|
|
1. 克隆合金存储库
|
|||
|
|
```
|
|||
|
|
git clone https://github.com/olliecoleman/alloy
|
|||
|
|
cd alloy
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2. 安装依赖项
|
|||
|
|
```
|
|||
|
|
glide install
|
|||
|
|
npm install
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
3. 启动开发服务器
|
|||
|
|
```
|
|||
|
|
go install
|
|||
|
|
alloy dev
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
4. 访问网站`http://localhost:1212`
|
|||
|
|
|
|||
|
|
_Alloy使用Node，NPM和Webpack_
|
