详解Windows10+golang+gRPC环境搭建-木庄网络博客

下面由golang教程栏目给大家介绍Windows10+golang+gRPC环境搭建，希望对需要的朋友有所帮助！

1、安装protoc

下载地址：https://github.com/protocolbuffers/protobuf/release
（注：https://github.com/protocolbuffers/protobuf 是其源码库，可以学习，如果源码库下载过慢，可以到码云上搜，很多同步的库，是国内的源，下载速度比较快，当然也可以自己在码云上创建个同步的库）

当前最新版本3.12.2
我的是windows10 64位操作系统，所以选择版本：protoc-3.12.2-win64.zip
直接用浏览器即可下载
如果网速不行，还可以用迅雷下载：https://github.com/protocolbuffers/protobuf/releases/download/v3.12.2/protoc-3.12.2-win64.zip
解压之后，将protoc.exe拷贝到$GOPATH/bin目录下
如果有多个GOPATH，放置到放公共第三方库的那个GOPATH中，这样多个project都可以用到

2、安装gRPC

gRPC源码：https://github.com/grpc/grpc-go.git
官网给的安装方法为：go get -u google.golang.org/grpc
但是国内经常会出现如下错误：

1 2	`$ go get -u google.golang.org/grpc` `package google.golang.org/grpc: unrecognized import path` `"google.golang.org/grpc"` `(https fetch: Get https://google.golang.org/grpc?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)`

因为google.golang.org在国内很难访问，所以会下载失败。
官网也给了多个解决方案：
https://github.com/grpc/grpc-go
我们采用第二种方法，直接将源码clone到本地
进入到$GOPATH/src目录，执行命令：

1	`git` `clone` `https://github.com/grpc/grpc-go.git $GOPATH/src/google.golang.org/grpc`

下载速度有时快，有时慢，非常慢的时候可以取消，重新触发，多试几次偶尔会很快。
下载完成后，安装gRPC:
