1、安装go1.15.3.windows-amd64，环境变量：GOROOT=C:\Go、GOPATH=C:\mygopath
2、安装goland-2020.2.3.exe，利用其Terminal窗口代替windows命令行 cmd
3、安装mingw5.1.6，修改环境变量：用户变量Path中增加C:\MinGW\bin
并将C:\MinGW\bin\mingw32-make.exe复制、粘贴、改名为make.exe
4、Go设置代理环境（便于无障碍下载github网站上的go项目）：
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.io,direct
5、在goland的Terminal窗口下载go项目frp
go get -u github.com/fatedier/frp
（get加上-u可以利用网络来更新已有的代码包及其依赖包）
下载后frp所在的文件夹为
C:\mygopath\pkg\mod\github.com\fatedier\frp@v0.34.1
6、编译go项目frp
运行
cd C:\mygopath\pkg\mod\github.com\fatedier\frp@v0.34.1
make
结果如下：
C:\mygopath\pkg\mod\github.com\fatedier\frp@v0.34.1>make

env CGO_ENABLED=0 go build -ldflags "-s -w" -o bin/frps ./cmd/frps
'env' 不是内部或外部命令，也不是可运行的程序
或批处理文件。
make: *** [frps] Error 1
出错处理：
1）手工设置环境变量CGO_ENABLED，在在goland的Terminal窗口输入：
go env -w CGO_ENABLED=0
2）修改Makefile
去掉只读属性，删除文件中的env CGO_ENABLED=0
3）再次make，顺利通过编译。结果如下：
C:\mygopath\pkg\mod\github.com\fatedier\frp@v0.34.1>make
go fmt ./...
go build -ldflags "-s -w" -o bin/frps ./cmd/frps
go build -ldflags "-s -w" -o bin/frpc ./cmd/frpc
C:\mygopath\pkg\mod\github.com\fatedier\frp@v0.34.1>
在C:\mygopath\pkg\mod\github.com\fatedier\frp@v0.34.1\bin文件夹可以找到两个文件
frpc
frps
改为frpc.exe和 frps.exe即可使用。
