通用教程 Go 下载环境安装

下载完成之后 无需配置环境变量

windows

打开cmd 执行

go version

查看go 安装版本检查是否安装成功

Mac/Linux

打开Terminal 执行

go version

查看go 安装版本检查是否安装成功

特别注意：
1、windows安装go建议不要安装到C盘可能会有权限问题，后期不好处理。建议安装到除C盘以外的盘。
2、安装完成后、执行go env 查看GOPATH 目录
GOPATH : Go 的工作空间，就是我们的开发和依赖包的目录（例如：我的是 D:gopath） ，此目录需要手动配置到系统环境变量（使用IDEA开发的可以忽略）
GOPATH 工作空间是一个目录层次结构，其根目录包含三个子目录：src、pkg、bin。

常见错误

1、windows下使用go get命令下载出现

exec: "gcc": executable file not found in %PATH%

解决方式

参考文章：https://www.cnblogs.com/zsy/p/5958170.html
软件下载地址：https://sourceforge.net/projects/mingw-w64/
安装完成软件后记得配置环境变量。
即可。

2、错误 could not launch process: EOF 解决

解决：

1、更新dlv，go get -u github.com/derekparker/delve/cmd/dlv

2、修改Goland的配置，Help->Edit Custom Properties中增加新版dlv的路径配置：dlv.path=/path/go/bin/dlv 

注：如替换后无效 请下载GoLang idea使用，可能是go插件版本不匹配

其他

1. IDE 的下载安装这里就不说，大家直接去这个地址下载就行。
Goland：https://www.jetbrains.com/go/download/#section=windows
或者直接使用IDEA、安装go插件也可以。不用去多下载一个开发工具。
