golang安装

下载地址为: https://golang.google.cn/dl/
如果是linux环境，解压到某个目录。然后配置/etc/profile设置相关环境变量
如果是windows环境，下载https://dl.google.com/go/go1.13.5.windows-amd64.msi，然后设置环境变量。
环境变量为：
GOPATH:%USERPROFILE%\go
GOPROXY:https://goproxy.io
GOROOT:C:\Program Files (x86)\go
Path环境变量，追加一条：C:\Program Files\Git\bin

打开dos，输入go env，看到一下则说明安装golang成功

git安装

安装git windows客户端
设置环境变量：
Path追加：
C:\Program Files\Git\cmd
C:\Program Files\Git\bin

vscode golang插件安装

由于一些技术原因，golang的安装包不能被安装。因此需要手动下载

进行如下命令进行目录切换：
cd %GOPATH%\src\github.com\golang
我这里的GOPATH是在D:\GoPath，大家这里一定要注意些
如果src目录下面没有github.com\golang文件夹请自行创建

完成目录切换后，开始下载插件包，在切换后的目录下进入命令行界面，可以用git bash：
git clone https://github.com/golang/tools.git tools

例如以下命令如果安装不成功：

go install github.com/nsf/gocode

则先用git下载相关go插件的源码，至/c/Users/Admin/go/src目录，然后
git clone https://github.com/nsf/gocode
mkdir -p github.com/nsf
mv gocode github.com/nsf/


安装：
```shell
Admin@PS20190603LEKJ MINGW64 ~/go/src
$ mv gocode github.com/nsf/

Admin@PS20190603LEKJ MINGW64 ~/go/src
$ go install github.com/nsf/gocode

Admin@PS20190603LEKJ MINGW64 ~/go/src

如果用git下载再安装比较麻烦，用下面一个操作：

Admin@PS20190603LEKJ MINGW64 ~/go/src
$ go get -u -v github.com/nsf/gocode
github.com/nsf/gocode (download)

Admin@PS20190603LEKJ MINGW64 ~/go/src

vscode常用的golang插件列表如下：
切换到C:\Users\Admin\go\src目录
